On the 20th of February 2013 the negotiation in OAO “RZD” took place, where the reliability of equipment of electric locomotives EP2K (production of OAO “Kolomenskiy zavod”), based on results of exploitation in 2012 was discussed.

At the meeting the management of OAO “RZD” noted a complete absence of claims to the quality of converters PSN100 Y2 produced by OOO ”Transconverter”.

The converter PSN100 Y2 is designed for auxiliary supply of electric locomotives which run on 3000 V DC, such as passenger electric locomotive EP2K. This converter has 3 output channels.

The first 3-phase output inverter (AIN1) supplies AC with fixed voltage and frequency values to such consumers as electric heaters, centrifugal fan electric drive, control circuits power unit etc. The total output power is 30 kVA.
The second output inverter (AIN2) supplies with variable AC voltage to the axial fan motor drive. The output power is 30 kVA.
The third output inverter (AIN3) supplies the brake compressor electric drive. The output power is 40 kVA.

Total output power of PSN100 Y2 converter is 100 kVA. The converter is designed as a unit to be installed into EP2K electric locomotive body.
By results of the qualifying and operational tests the commission made the decision to give the letter “A” to the technical documentation of PSN100 U2 converter.
