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

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.
