... Description The FW250R1 and FW300R1 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 maximum power rat- ings from 250 W to 300 typical full-load efficiency of 90 ...
