Logic Control
Power failure:
TTL Logic signal goes high 50-150 msec after 5 V output. It goes low at least 4 ms before loss of
regulation
Remote on/off:
Requires an external contact (N.O or N.C) to inhibit outputs
DC - OK:
TTL logic goes high 50-150 msec after the output. It goes low when there is loss of
regulation.
Remote sense:
Compensates for 0.5 V lead drop minimum, will operate without remote sense connected. Reverse
connection protected

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.
