Description
The JC050B, JC075B, JC100B Power Modules are dc-dc converters that operate over an input voltage range of
18 Vdc to 36 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the inputs, allow-
ing versatile polarity configurations and grounding connections. The modules have maximum power ratings from
50 W to 100 W at typical full-load efficiency of 85%.
The sealed modules offer 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.
