In September 2013 designing bureau of OOO ”Transconverter” began the development of new version of converter PS70 YHL4, designed for bench testing of asynchronous traction motors.

It will be possible to use touchscreen to install, store and choose acceleration and deceleration algorithms of the test asynchronous traction motor in the new version of converter PS70 YHL4.

Converter PS70 UHL4 * converts three-phase 380 V 50 Hz voltage to three-phase 250 … 600 V 50…120 Hz frequency. The nominal output power is 50 kVA. Maximum output power of the inverter is 70 kVA.

Since 2010, the converters PS70 YHL4 successfully operated in OOO “Uralskie Lokomotivy” and in OOO ”Siemens”
