Designed to power any type of communications equipment requiring -48 vdc, including telecomm switching systems and transmission equipment, the BZA 130 21 is a bulk power system that provides high current power for loads up to 10 kA. The system features a bulk power architecture designed for high customer load applications. Its high-density design is said to result in one of the smallest footprints available.
