Output
Maximum power...................With cover: 350 W with 30 CFM forced air,
(-C) (-CF) (-CEF)
Adjustment range ................. 2:1 wide ratio
Supervisory outputs ............. 5 V @ 500 mA regulated, 12 V @ 150 mA x2
Hold-up time.........................20 ms @ 350 W load, 115 VAC nominal line
at factory voltage setting
Overload protection..............Short circuit protection on all outputs. Case
overload protected @ 110-145% above
peak rating
Overvoltage protection ......... 5 V output: 5.7-6.7 VDC. Other outputs
10% to 25% above nominal output
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
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 min. 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 adjusment requires a 1A load.
Note: -CF suf fix added to the model number indicates cover with yop fan;
-CEF suffix added to model number indicates end-mounted fan chassis.
