Output
Maximum power With cover: 250 W with 30 CFM forced air. (-C) (-CF) (CEF) 2:1 wide ratio 5 V @ 100 mA regulated; 12V @ 500 mA 20 ms @ 250 W load, 115 VAC nominal line at factory voltage setting Short circuit protection on all outputs. Case overload protected @ 110-145% above peak rating 5 V output: 5.7 to 6.7 VDC. Other models 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 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.
Environmental

Notes: 1. Peak current lasting <30 seconds with a maximum 10% duty cycle. 2. At 25C including initial tolerance, line voltage, load currents and output voltages adjusted to factory settings. 3. Peak-to-peak with 20 MHz bandwidth and 10 F in parallel with a 0.1 F 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.
