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.
