product introduction:

DC power supply panel is an important operation and control power supply for substations, power distribution rooms, rail transit traction stations and other places. It provides stable and reliable uninterrupted DC power supply for high-voltage switches, relay protection, automatic devices, accident lighting, etc. It is the core equipment to ensure the safe operation of the power supply system.

product features:

  1. Modular high-frequency switch, high efficiency: high-frequency switching power supply module, N +1 redundant design, hot-swappable module, easy expansion and maintenance, machine efficiency ≥ 90%, energy saving and low consumption.
  2. Automatic intelligent management: equipped with intelligent monitoring system, to achieve automatic charging, floating charge, temperature compensation, battery management, without frequent manual intervention.
  3. power supply is stable and reliable: when AC power is off, the battery is automatically and seamlessly put into operation to ensure uninterrupted power supply for protection, control and trip circuits and meet the power consumption of important loads under accident conditions.
  4. protection function: it has multiple protections such as overvoltage, undervoltage, overcurrent, short circuit, phase loss, battery overcharge and overdischarge, insulation monitoring, grounding alarm, etc., and automatic fault alarm.
  5. Remote monitoring and communication: it supports RS485, Ethernet, Modbus and other communication interfaces, and can be connected to the integrated self-system to realize telemetry, remote signaling, remote control and remote adjustment.
