Combined Power Supply BPK-5M for Relay Protection and Automation

BPK-5M are designed to provide uninterrupted power supply of relay protection and automation devices (RPA) and circuit breaker drives at power facilities with alternating operating current, not equipped with guaranteed voltage sources. BPC-5M provide power supply of RPA devices and circuit breaker drives with rectified current both in normal and emergency modes of operation of power grids in case of all types of short circuits accompanied by voltage reduction. BPC-5M have different output voltages. BPC-5M together with relay protection devices are designed for installation on control panels, panels and in relay cabinets of complex switchgear (switchgear) and control panels of power stations and substations.
