Product Description

Product Description

  DC panel used in large, middle and small power generating plant or substation, output DC source for the ON/OFF operation, relay protection, auto control, lighting tor high voltage switches at normal status or fault status. The reliability of the DC panel is what other power source devices can't substitute always. It can meet with such high reliability for the auxiliary power source in substation and power plant.
        This series of DC panels has such features as small size, high efficiency, high technical index, module design n+1 heat redundancy backup, high reliability, module design . Adopted the world's latest advanced technology of Resonant voltage dual-loop control resonant switch power source"four remote operations, standard RS-485 and RS232 interfaces provided tor automation, also the other performances excel over the traditional power source of similar use.
