Product overview

DC panels are used in large, medium and small power plants and substations to provide DC power for the opening and closing, relay protection, automatic control, emergency lighting, etc. of high-voltage switches under normal operation and accident conditions. The reliability of the DC panel is irreplaceable by other power supply devices. It can meet the high reliability requirements for power supply in substations and power plants.

This series of DC panels has small size, high efficiency, superior technical indicators, modular design, n+1 redundant hot backup, high reliability, and adopts the worlds leading "resonant voltage type double-loop controlled resonant switching power supply technology" and "Four Remote ” function, equipped with standard RS-485 and RS232 interfaces, easy to interface with automation systems, and other performance advantages over traditional power supplies, it is accepted by the majority of users.

This product complies with: GB/T19826-2005 "General technical conditions and safety requirements for DC power equipment in power engineering"; JB/T5777.4-2000 "General technical conditions and safety requirements for DC power equipment in power systems"; JB/T8456-1996 "Low-voltage DC complete switchgear"; DL/T459-2000 "Technical conditions for ordering DC power cabinets in power systems"; DL/T5041-95 "Technical regulations for in-plant communication design of thermal power plants"
