(the ce mark is placed on selected products.) description the jw050b, jw075b, JW100B, and jw150b power modules are dc-dc converters that operate over an input voltage range of 36 vdc to 75 vdc and provide a precis ely 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 88%. the sealed modules offer a metal baseplate for excellent thermal performance. threaded-through holes are pro- vided to allow easy mounting or additi on of a heat sink for high-temperatur e applications. the standard feature set includes remote sensing, output trim, and remote on/off for convenient flexibility in distributed power applications. the jw050b, jw075b, JW100B, and jw150b power modules use advanced, surface-mount technology and deliver high- quality, efficient, and compact dc-dc conversion.
