In September 2020 Transconverter LLC introduced one-of-a-kind bench converter PS150 YHL4 for power supply of the electromagnetic shaker table of VElNII (Novocherkassk).

The bench converter PS150 YHL4 generates the output single-phase voltage with a regulated effective range from 0 to 250 V and frequency from 0 to 50 Hz from three-phase 400 V, 50 Hz AC.

This device has maximum output value 250 kVA.

The converter PS150 YHL4 replaced the current outmoded electromechanical power unit which has unstable frequency of the output voltage and a low efficiency.
