JW075A5 Summary of contents
Page 1
... Description The JW075A5, JW075B5, and JW075C5 Power Modules are dc-dc converters that operate over an input volt- age range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The output are fully isolated from the input, allowing versatile polarity configurations and grounding connections. The modules have a maximum power rating typical full-load efficiency of 85% ...
