Unlike 'static' phase converters, they are not limited to driving a single motor, nor do they limit the motor's torque or have a lower limit to output power. The Booster range of 3 phase converters has the unique feature of electronically switching up to 600 % of rated power for up to 10 seconds for 'hard starting' or momentary overload. Solid state switching takes place as the power waveform crosses zero, minimising electromagnetic interference. There are no electromechanical contacts to wear out or open at full voltage (emitting interference).

Using<b> electronic switching </b>the Booster E Converters cope well with machines and motors <b>starting under load. </b></font></p> <p><font size="2">They can run <b>one or many electric motors</b> or one or <b>many machines simultaneously</b>.</font></p> <p><b><font size="2">Motor sizes can be as large as the total capacity of the Phase Converter.</font></b> </p> <p><font size="2">There is no need so to select a larger Converter than actually needed.</font></p> <div align="center"> <p><br> <br> <b><i><font size="3">Whas to expect from a Booster E?<br> </font></i></b><br> </p> </div> <p><font size="2">Compared to your local power company, a Booster E is still a compromise but a viable option, even coping with motor hard-starts. This is stated to prevent unwarranted expectations of the equipment. Converters have weaknesses and strengths which should be considered before a purchase is made.<br> </font></p> <p><font size="2">Boosters have a low purchase cost, far lower than the cost to bring three-phase to your premises via power lines. Operating cost is very low, about five percent of the electrical cost of the operated load.<br> </font></p> <p><font size="2">A Booster E in a standard, multi-motor installation will not quite balance each line's power as well as a utility-supplied, three-wire, three-phase system. The quality of the Booster´s three-phase output depends a lot on the quality and stability of the single phase input line. Since output currents sometimes increase to 600% of the maximum continuous currents, the input lines are loaded with higher currents as well.<br> </font></p> <p><font size="2">A Booster E4 draws about 18A maximum continuous input current. During motor starting it can increase to about 110A peak current for a fraction of a second. This could be a longer period of time if the starting motor has to accelerate a heavy mass. Motor rated fuses accept high currents during the start-up time of a motor.<br> </font></p> <p><font size="2">High input currents may result in input voltage drops. When motors are starting under load, we have seen voltage drops from 230V down to 170V. Because the nature of a Booster is a transformer, this will result in a voltage drop at the three phase output from 3 x 400V to about 3 x 280V. Under these conditions, motors will not accelerate as fast as they should.<br> </font></p> <p><font size="2">If the time period of excessive input currents is extended, either the input fuse will blow, or the protective overload switch in your equipment will trip.<br> </font></p> <p><font size="2">To overcome these problems, it pays to install oversized cables between your fuse box and the Booster´s input. If the voltage drop of the supply side is reduced, motors on the output side will accelerate faster.<br> </font></p> <p><font size="2">Low input or output voltages will not do any harm to the converter. They only reduce the overall efficiency.<br> </font></p> <p><font size="2">Compared with the power company's grid, Boosters may not maintain close voltage balance over a wide range of operation. Line-to-line three-phase voltages may vary somewhat with changing loads. If you have voltage-sensitive equipment such as some computerised machine tools (CNC), best results can be obtained by using a separate Booster for the CNC, and another one for general workshop machines.<br> </font></p> <p><font size="2">By analysing the strengths and weaknesses of each option, utility three-phase or a converter, you minimise your disappointments with either. Utility supplied three-phase power brings higher electrical costs than single to three-phase converter power because someone has to pay the purchase and maintenance cost of the extra lines and extra street-transformers, out in all weathers.<br> </font></p> <div align="left"> <p><font size="2">A Booster is owned by you: when you don't need three-phase, you turn it off and you're not paying any line charges.

Single-phase requires only one hot wire and one transformer. Upgrading an installation from single to three-phase often costs thousands of Euros per mile.</font></p> <p align="left"><font size="2">The electricity company has to recover these costs by charging for installation, a new meter, daily or monthly line charges, billing based on peak usage, and higher kilowatt per hour rates. These costs should be taken into account when comparing the purchase of a Booster or EC-Kit and connecting a utility-supplied three-phase supply. Boosters and EC-Kits only need a simple installation of an industrial single-phase wall-socket. All existing wiring to the single-phase remains the same. A Booster or the EC-KIT combined with a seperate motor can operate any combination of machines, motors, welders, and other electric loads.</font></p> <p align="left"><font size="2">The EC-Kit is connected to an electic motor which then produces 3x 240V = 380 V three phase power.</font></p> <p align="left"><font size="2">The EC-Kit is - as it doesn´t contain a motor-generator - much smaller, lighter an easier to transport then a booster. </font></p> <p align="left"><font size="2">The only you need to run the EC-KIT as a converter is a seperate standing (existing) motor. </font><font size="2">The EC-KIT contains a 3-phase-cable you simply attach to the three phases of this motor. </font></p> <p align="left"><font size="2">The EC-KIT also includes a cable to connect to your the 220 V - industrial - plug. This makes your motor run. The motor will now work as a 380 V three phase power supply.</font></p> <p align="left"><font size="2"> Now you can to connect the 380 V three phase power line of the machine you need to run.</font></p> <p align="left"><font size="2"><strong>For your understanding:</strong></font></p> <p align="left"><font size="2">Inside the EC-KIT, power capacitors are continuously charged and discharged into the attached motor-generator. Depending on external start and load conditions, different capacitors are involved in the process of charging and discharging.</font></p> <p align="left"><font size="2">Capacitors, charged with high voltages, have to be switched in and out, depending on demand. Boosters are based on solid-state capacitor switching, using no electromechanical contacts to wear out. Switching is performed at zero voltage and zero current transitions. This minimises stress to capacitors, components, motors, and to the supply lines.</font></p> <p align="left"><font size="2">Electronic switching in the EC-KIT is free of sparks and stress, as found with contactor switching. No EMI or RFI emission is found with a Booster. No line disturbances will be generated. Lifetime of all components is extremely long.</font></p> <p align="center"><font size="3" color="red"><b><em>How to install an EC-KIT:</em></b></font></p> <p align="left"><font size="2">Our standard E4-EC-Kits are only as large as a Suitcase.

If motors start under load (e.g. submersible pumps, vehicle lifts) or have to change their direction instantly (as in CNC machines), this is a unique and very useful feature.</font></p> <p align="left"><font size="2">Zero voltage switching (controled by the EC-Kit) and dry polypropylene capacitors (included in the EC-Kit are the guarantee for long life expectation.<br> The compact internal logic and switch circuitry is epoxy-resin protected against moisture and dust.</font></p> <p align="left"><font size="2">Electromagnetic and electrostatic disturbances, over and undervoltages, and short circuits are covered by EMI filters and well rated power semiconductors.<br> Solid-state switches used in a EC-KIT are high-voltage and high-current types, tested for 2200V and constructed to withstand currents of up to 4000A (Booster 8).<br> Bearings in the internal motor-generator are greased for life.</font></p> <p align="left"><font size="2">Using such a separated module is not unusual: Isomatic for example produces the larger Booster-types with standing-alone controling units:</font></p> <p align="center"><img src="/Bilder/BoosterE16.jpg" width="320" height="240" border="0"></p> <p align="left"><font size="2">The E4-type EC-KITs are much smaller an look like an aluminium suit-case.</font></p> <div align="left"> <p align="center"><font size="3" color="red"><b><em>When to buy an EC-KIT instead of a booster</em></b></font></p> <p align="left"><font size="2">Buying an EC-KIT instead of a booster makes sense if you either already have a motor you can run with the EC-KIT or if you want to be more flexible:</font></p> </div> </div> <ul> <li> <div align="center"> <div align="left"><font size="2">The advantage of building your single to three-phase converter is not only saving the costs of the electic motor but also the costs and easyness of transportation.

These are e.g. mills, drills, saws, grinders etc.</font></p> </div> <p align="left"><font size="2">There are other applications where a EC-KIT-controlled converter will perform better than any other converter: refrigeration systems, hydraulic machines, printing presses, wide-belt sanders, heavily loaded submersible water pumps, planers, conveyors, lifts, thicknessers, air compressors, dust collectors, high-speed high-volume fans, vacuum pumps.</font></p> <p align="left"><font size="2">Metal lathes without clutch, with a high speed spindle (over 750 rpm) and possibly an older and inefficient type of motors, are very demanding. High-speed lathes that start under full load require high starting torques.<br> A Booster (or a motor-generator driven controlled by an EC-KIT) will cope with all these hard-starts.</font></p> <p align="left"><font size="2">In case of hard-start conditions, some manufacturers of phase converters suggest using a converter twice the size of the operated motor, which is uneconomic and inefficient.</font></p> <p align="left"><font size="2">This is not the case with our Boosters or with your motor controlled by an EC-KIT. The kW size quoted will start a motor or machine of the same kW rating.</font></p> <p align="left"><font size="2">A E4 or D4 (Economy or Differential mode) EC-KIT / Booster connected to single phase 240V and running under full 4 kW load, will draw about 18A from the 240V supply line. <br> When machines or motors start, boost-mode is activated.<br> Depending on the load and on the quality of the supply line, the input current may rise to 100A or more for a brief moment. If the supply cable is weak, voltage drop will occur at the input side of the Booster.<br> The same relative voltage drop will be found at the EC-KIT output: Motors will not accelerate as fast as they should and will not cope well with high loads.<br> It is essential to use a well sized, or better oversized, single-phase supply cable.</font></p> <p align="left"><font size="2">Extreme hard-starts will occur with applications like refrigeration systems, compressors, metal lathes, hydraulic systems, welders, wheel balancers, submersible pumps. In this instance, an even better supply cable is essential.<br> A Booster should always be mounted as close to the single-phase service as possible.</font></p> <p align="left"><font size="2">EC-KIT Controlled Motors / Boosters are versatile and powerful, and are a viable option compared to three-phase power supplied by an electricity company.<br> They can be compared to a generator set. Instead of a diesel or petrol motor, the driving power comes from the input supply line.</font></p> <p align="left"><font size="2">The Booster / EC-KIT has an important advantage over a gen-set: Boost-mode, the capability to start motors under load - like a generator set that becomes five or six times more powerful for a brief moment.</font></p> <p align="left"><font size="2">With a EC.KIT / Booster the three output line voltages are stabilized and balanced. This is required when operating inverters (welders, variable speed drives) or when large motors are continuously running under full load.</font></p> <p align="left"><font size="2">Boosters build with an EC-KITmodules are robust and immune from incoming line disturbances, over- and undervoltage conditions and even frequent short circuits. They resist the "dirty" supply from rural power lines with all their line disturbancies and harmonics. <br> Brown-outs, black-outs, unstable power lines, over and under voltage will not do any harm to a Booster.</font></p> <p align="left"><font size="2"><strong>Hard-starts</strong>: The unique Booster converter technology concept copes well with the most difficult applications: <br> Metal lathes without clutches, hydraulic systems, refrigeration units, CNC machines, wheel balancers, older types of compressors, deep submersible pumps, conveyors or lifts starting under heavy loads. <br> A STARTER KIT will cope with start-stop applications and frequent forward-reverse operation. <br> A STARTER KIT can also be used with variable speed drives, motor soft starters and all welders.</font></p> <p align="left"> <font size="2"><strong>Compliance</strong>: Radio frequency interference and electromagnetic interference are well below legal limits.

They resist the "dirty" supply from rural power lines with all their line disturbancies and harmonics. <br> Brown-outs, black-outs, unstable power lines, over and under voltage will not do any harm to a Booster.</font></p> <p><font size="2"><strong>Hard-starts</strong><br> The unique Booster converter technology concept copes well with the most difficult applications: <br> Metal lathes without clutches, hydraulic systems, refrigeration units, CNC machines, wheel balancers, older types of compressors, deep submersible pumps, conveyors or lifts starting under heavy loads. <br> A STARTER KIT will cope with start-stop applications and frequent forward-reverse operation. <br> A STARTER KIT can also be used with variable speed drives, motor soft starters and all welders.</font></p> <p> <font size="2"><strong>Compliance</strong><br> Radio frequency interference and electromagnetic interference are well below legal limits. EuroTech Boosters are officially tested for EMC compliance. <br> They do comply with applicable emission and radiation standards.</font></p> <p><font size="2"><strong>Input and Output Voltages</strong><br> European style (IEC) single phase supply voltage is 230V (in some countries 220 or 240V). Output voltages are always three phase 400V (or 3x380V or 3x415V).</font></p> <p><font size="2">With a Booster STARTER KIT the three output line voltages are stabilized and balanced.

In some countries and rural areas, this supply is not provided or is only provided at a high cost. Single to three phase converters are suitable for farms, workshops, etc, where the site lacks 3-phase supply and within large buildings where all 3 phases are not close to the equipment location.<br> </font></p> <p><font size="2">Where three-phase power is needed, a simple calculation can be made to compare the cost of a <b>three-phase utility installation</b> (new pole transformer, additional power lines) with the cost of a <b>single to three-phase converter</b>.

The solid state switching takes place as the power waveform crosses zero, minimising electromagnetic interference. There are no electromechanical contacts to wear out or open at full power voltage with the inevitable interference emission. Using<b> electronic switching </b>the Booster E Converters cope well with machines and motors <b>starting under load. </b></font></p> <p><font size="2">They can run <b>one or many electric motors</b> or one or <b>many machines simultaneously</b>.</font></p> <p><b><font size="2">Motor sizes can be as large as the total capacity of the Phase Converter.</font></b> </p> <p><font size="2">There is no need so to select a larger Converter than actually needed.</font></p> <div align="center"> <p><br> <br> <b><i><font size="3">Whas to expect from a Booster E?<br> </font></i></b><br> </p> </div> <p><font size="2">Compared to your local power company, a Booster E is still a compromise but a viable option, even coping with motor hard-starts. This is stated to prevent unwarranted expectations of the equipment. Converters have weaknesses and strengths which should be considered before a purchase is made.<br> </font></p> <p><font size="2">Boosters have a low purchase cost, far lower than the cost to bring three-phase to your premises via power lines. Operating cost is very low, about five percent of the electrical cost of the operated load.<br> </font></p> <p><font size="2">A Booster E in a standard, multi-motor installation will not quite balance each line's power as well as a utility-supplied, three-wire, three-phase system. The quality of the Booster´s three-phase output depends a lot on the quality and stability of the single phase input line. Since output currents sometimes increase to 600% of the maximum continuous currents, the input lines are loaded with higher currents as well.<br> </font></p> <p><font size="2">A Booster E4 draws about 18A maximum continuous input current. During motor starting it can increase to about 110A peak current for a fraction of a second. This could be a longer period of time if the starting motor has to accelerate a heavy mass. Motor rated fuses accept high currents during the start-up time of a motor.<br> </font></p> <p><font size="2">High input currents may result in input voltage drops. When motors are starting under load, we have seen voltage drops from 230V down to 170V. Because the nature of a Booster is a transformer, this will result in a voltage drop at the three phase output from 3 x 400V to about 3 x 280V. Under these conditions, motors will not accelerate as fast as they should.<br> </font></p> <p><font size="2">If the time period of excessive input currents is extended, either the input fuse will blow, or the protective overload switch in your equipment will trip.<br> </font></p> <p><font size="2">To overcome these problems, it pays to install oversized cables between your fuse box and the Booster´s input. If the voltage drop of the supply side is reduced, motors on the output side will accelerate faster.<br> </font></p> <p><font size="2">Low input or output voltages will not do any harm to the converter. They only reduce the overall efficiency.<br> </font></p> <p><font size="2">Compared with the power company's grid, Boosters may not maintain close voltage balance over a wide range of operation. Line-to-line three-phase voltages may vary somewhat with changing loads. If you have voltage-sensitive equipment such as some computerised machine tools (CNC), best results can be obtained by using a separate Booster for the CNC, and another one for general workshop machines.<br> </font></p> <p><font size="2">By analysing the strengths and weaknesses of each option, utility three-phase or a converter, you minimise your disappointments with either. Utility supplied three-phase power brings higher electrical costs than single to three-phase converter power because someone has to pay the purchase and maintenance cost of the extra lines and extra street-transformers, out in all weathers.<br> </font></p> <div align="left"> <p><font size="2">A Booster is owned by you: when you don't need three-phase, you turn it off and you're not paying any line charges.
