Dc panel is used in large, small and medium-sized power plants and substations, providing DC power supply for high-voltage switch in normal operation and emergency state, relay protection, automatic control, accident lighting, etc. The reliability of DC panel can not be replaced by other power supply devices. It can meet the high reliability requirements of power supply in substation and power plant.
This series of DC panel is small size, high efficiency, superior technical indicators, modular design, n+1 redundancy heat backup, high reliability, the module adopts the world’s leading “resonant voltage type double circuit control resonant switching power supply technology”, “four remote”function, equipped with standard RS-485 and RS232 interface easy to connect with the automation system. And other performance is superior to the absolute advantage of traditional power and accepted by the majority of users.
