... Description The QHW050G1, QHW075G1, and QHW100G1 Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are fully iso- lated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings from typical full-load efficiency of 86% ...
