... Description The QHW050Y1, QHW075Y1, and QHW100Y1 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 maxi- mum power ratings from typical full-load efficiency of 82% ...

Input Ripple Rejection (100—120 Hz) Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus- ing is not included ...
