... 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% ...

... Derating curves for forced-air cooling without a heat sink are shown in Figures 19 and 20. These curves can be used to determine the appropriate airflow for a given set of operating conditions. For example, if the unit with airflow along its length dissipates heat, the correct airflow °C environment is 1.0 m/s (200 ft./min.). Lineage Power ...
