Description
The JW050A, JW075A, JW100A, and JW150A Power Modules are dc-dc converters that operate over an input voltage range of 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 maxi- mum power ratings from 50 W to 150 W at a typical full-load efficiency of 84%. The sealed modules offer a 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. The JW050A, JW075A, JW100A, and JW150A Power Modules use advanced, surface-mount technology and deliver high- quality, efficient, and compact dc-dc conversion.

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 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.
