Product Summary
The QHW075F1 Power Module is a kind of dc-dc converter that operates over an input voltage range of 36Vdc to 75 Vdc and provides a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The QHW075F1 has maximum power ratings from 33 W to 66 W at a typical full-load efficiency of 85%. The sealed modules offer a metal baseplate for excellent thermal performance. Threaded-through holes are provided to allow easy mounting or addition of a heat sink for high-temperature applications. The QHW075F1 is ideal for: (1)Distributed power architectures; (2)Communications equipment; (3)Computer equipment.
