Description15W DC/DC converters low wattage range, for the emerging trend of distributed power applications, featuring 4:1 wide DC input range and 1500VDC input/output isolation, NSD15 series has two kinds of DC input level – 12V, 48V, and seven kinds of DC output level accross the series'. Standard functions include remote ON/OFF control, short circuit, over load, and over voltage protections. These economical gadgets are suitable for applications using distributed power architecture that transfer the high DC bus voltage to lower DC working voltage at the location of the load.
