The JFC-Series 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 output is fully isolated from the input, allowing versatile polarity configurations and grounding connections.The modules have maximum power ratings from 50 W to 100 W at typical full-load efficiencies of 85%.
The sealed modules have metal baseplates for excellent thermal performance. Threaded-through holes are provided for easy mounting or adding a heat sink for high-temperature applications. Listed above are the enhanced features for convenience and flexibility
JFC100C Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
