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 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 pro-
vided to allow easy mounting or addition of a heat sink for high-temperature applications. The standard feature set
includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed power applications.
The QHW Series Power Modules use advanced, surface-
mount technology and deliver high-quality, efficient, and
compact dc-dc conversion.
