Power supply unit IP-1 110/230-32 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 on-board DC network with a rated voltage of 110 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 ensure the possibility of operating the IP from the onboard DC network of a passenger railway car when the supply voltage changes in the range of 83 ... 147 V.
