DC Distribution Panel

Hits: 27

The DC panel provides uninterrupted power supply to control circuits, relay protection, automation, and signaling systems at electrical stations/substations during grid outages by automatically switching to backup battery power. When main power is restored, it automatically charges batteries while simultaneously powering loads. Designed for industrial environments.

Structure:

The device consists of a frame metal structure covered with powder paint to prevent the appearance of corrosion, with a partition in form 1. For access to the shield from the front side there are doors that are locked by a key. In the lower part of the body of the device, a PE grounding bus is installed. The cable entry and connection is carried out in the upper part of the shield.  The device fully meets the requirements of standard RT RC GOST P 51321.1-2010 (IEC 60439-1-92).
