The QW Series Power Modules use advanced, surface-mount
technology and deliver high-quality, efficient, and compact
dc-dc conversion.
Description
The QW050A1 and QW075A1 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 rat-
ings from 50 W to 75 W at a typical full-load efficiency of 84%.
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.
