Power supply unit IP-1 55/230-16 UHL4

The power supply unit IP-1 55/230-16 UHL4 (hereinafter referred to as "IP") is designed to power consumers of alternating current with a voltage of 230 V 50 Hz installed on passenger railway cars, locomotives, electric trains, diesel trains (TV sets, refrigerators, microwave ovens) having an onboard DC network with a nominal voltage of 55 V.

IP provides start of the electric motor of the refrigerator with power up to 240 W.

The range of regulation and the accuracy of maintaining the output voltage provide the ability to operate the power supply from the on-board DC network when the supply voltage changes in the range of 39 ... 72 V.
