Industrial and process control, distributed power, ATE, communications, defense and aerospace. With its high frequency zero voltage switching (ZVS) topology, the HDC consistently delivers high efficiency across the input line range. Modular HDC and downstream DC-DC products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point-of-load.
