... Description The QHW050F1-Q, QHW075F1-Q, and QHW100F1-Q 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 isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings from typical full-load efficiency of 85% ...
