On December 25, 2018, the qualifications committee recommended to assign A character to the engineering and production documentation of PSN110 U1 auxiliary converter.
PSN110 U1 high-voltage converter is a component part for electrical trains operated on road sections with a voltage of 3000 V DC. It is designed for high voltage conversion (2200…4000 V) of overhead system into voltages required for power supply of lighting circuits, control circuits, air conditioning systems, compressor, battery charge, etc.
PSN110 U1 converter has two output channels with three-phase voltages 380 V and 220 V, 50 Hz.
PSN110 U1 converter nominal output power is 110 kVA.
So far, over 300 PSN110 U1 converters have been produced.
