FW250C1 Lineage Power, FW250C1 Datasheet

Page 1

... Description The FW250C1 and FW300C1 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 87% ...

... The CURRENT MON pin provides a dc voltage propor- tional to the dc output current of the module given in the Feature Specifications table. For example, on the FW250C1, the V/A ratio is set at 250 mV/A ± 10 °C case full load current of 16.7 A, the voltage on the CURRENT MON pin is 4.18 V. The current mon- itor signal is referenced to the SENSE(– ...
