Case overload protected CB Certicfi ate and report 2186 10 - 145% above peak rating CE Mark (LVD) 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.

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 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.
