Operational Locking Circuit Power Supply Cabinet SHPOBR.CES for Reliable Circuit Control

The disconnector operational interlocking power supply cabinet is a low-voltage complete device of cabinet design intended for power supply of disconnector operational interlocking circuits and operational interlocking automatics.

The SHPOBR has the following functions:

- input and distribution of electrical energy from AC and DC sources with galvanic isolation between the power source and the consumer;

- insulation resistance monitoring;

- visual indication of the equipment status;

- surge protection (optional);

- protection of outgoing lines against overcurrents and overloads;

- control of power supply voltage of operational interlock circuits
