Supervisory output 5 V @ 100 mA regulated; 12 V @ 500 mA
Adjustment range 2:1 wide ratio
Hold-up time 20 ms @ 250 W load, 115 VAC nominal line
Overload protection Short circuit protection on all outputs. Case overload protected @
10 - 145% above peak rating
Overvoltage protection 5 V output: 5.7 to 6.7 Vdc.
Other models 10% to 25% above nominal output
Logical 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
7. This product is a Component Power Supply and is only for inclusion by professional installers within other equipment and must not be
operated as a standalone product. EMC compliance to appropriate standards must be veried at the system level. This product is for sale
to OEMs and System Integrators, including through Distribution Channels. It is not intended for sale to End Users.
Note: -CF sufx added to the model number indicates cover with top fan. -CEF sufx added to the model number indicates cover with dual end mounted fan cover and AC inlet.
