See derating curves for full performance details. Combined output power of main output and fan supply shall not exceed the max power rating. Ripple is peak to peak with 20 MHz bandwidth and 10 F tantalum capacitor in parallel with a 0.1 F capacitor at rated line voltage and load ranges. Output ripple can be more than 10% of the output voltage at -40C. With header type output connector, VOF-350-12 max current is 18.75 A (225 W) and VOF-350-15 max current is 18 A (270 W) with 13 CFM forced air cooling. All specifications are measured at Ta=25C, nominal input voltage, and rated output load unless otherwise specified.
