Voltage Stabilization Device - USN.CES for Reliable Power Supply

Voltage Stabilisation Device (VSD) is a low-voltage complete device of cabinet design with a DC voltage converter providing stabilisation of output voltage at input voltage reduction and is intended for use in DC operating systems of electric power stations and substations having accumulator batteries.

The USN consists of voltage converters, monitoring and control equipment, as well as protection equipment for main and auxiliary circuits.

The STB-501F device provides selective operation of the DIS protective devices and does not limit the short-circuit current from the battery to the consumers.
