Description
The JC050C, JC075C, JC100C 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, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings from 50 W to 100 W at typical full-load efficiency of 88%. 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.

periods can adversely affect device reliability. Table 1. Input Specifications CAUTION: This power module is not internally fused. An input line fuse must always be used. safety agencies require a normal-blow, dc fuse with a maximum rating of 20 A (see Safety Considerations section). type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.
