Vicor DCM3623 Isolated and Regulated DC-DC Converters operate from an unregulated, wide-range input to generate an isolated output. With high-frequency zero voltage switching (ZVS) topology, the DCM3623 converters consistently deliver high efficiency across the input line range. Modular DCM3623 converters 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. Vicor DCM3623 Isolated and Regulated DC-DC Converters are suitable for a variety of applications. This includes railroad applications where the 3000VDC isolation voltage and wide 43VDC to 154VDC input voltage range can be used in both 72VDC and 110VDC nominal systems.
