... Heat sinks available for extended operation Description The FC250A1 Power Module is a 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 maximum power ratings of 100 typical full-load efficiency of 85% ...
