Notes:

1. Maximum output power of 275 W with 13 CFM forced air cooling, and 160 W with natural convection cooling at 100 to 264 Vac.

2. Combined output power of main output and fan supply shall not exceed the max power rating.

3. Ripple is peak to peak with 20 MHz bandwidth and 10 µF tantalum capacitor in parallel with a 0.1 µF capacitor at rated line voltage and load ranges.

4. Output ripple can be more than 10% of the output voltage at -40°C.

5. All speciﬁcations are measured at Ta=25°C, nominal input voltage, and rated output load unless otherwise speciﬁed.
