Notes:

1. Peak current lasting <30 seconds with a maximum 10% duty cycle.

2. At 25°C including initial tolerance, line voltage, load currents and output voltages adjusted to factory settings.

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

4. If optional CF or CEF fans are not used, 30CFM forced air cooling needs to be provided and is required through

the length of the power supply. Not convection rated.

5. Output voltage adjustment requires a minimum load.

6. Remote inhibit resets OVP latch

Note: -CF suffix added to the model number indicates cover with top fan.

-CEF suffix added to the model number indicates cover with dual end mounted fan cover and AC inlet.
