In June 2022, Transconverter delivered to VElNII (Novocherkassk city) a unique converter PS50 YHL4 for electric power of two electromagnetic vibrostand.

The converter PS50 YHL4 forms from a three-phase voltage 400 V, 50 Hz AC two unrelated of each other output one-phase voltages with a regulated RMS from 20 to 200 V and a frequency from 5 to 150 Hz.

Each output channel of the converter has an output power 25 kVA.

The converter PS50 YHL4 is meant to substitute the existing outmoded electromechanical unit which has an unstable output voltage frequency and a low efficiency.
