Description
The QW030-Series Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to
75 Vdc and provide precisely regulated dc outputs. The outputs are fully isolated from the inputs, allowing ver-
satile polarity configurations and grounding connections. The modules have maximum power ratings of 30 W
to 36 W at a typical full-load efficiency of up to 88%.
These encapsulated modules offer a metal case for optimum thermal performance. Threaded-through holes are
provided 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.
