Description
The QC/QW030-Series Power Modules are dc-dc converters that operate over an input voltage range of
18 Vdc to 36 Vdc or 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 of 30 W at a typical full-load efficiency of up to 86%.
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.
