1. OCP %
0 100%
2. OCP Type --- Constant current
3. Knee point protection --- None, No damage at knee point operation
4. Short circuit protection --- Yes
5. Foldback protection --- Output shut down when power supply changes from CV to CC mode, manual reset by front panel OUT
button or Digital Communication, user-selectable.
6. Foldback response time S Min = 0.25/Max = 25, Default = 0.25
Settable via “FBD” command using Digital Communication command.
7. OVP Type --- Inverter shut-down, manual reset by AC input recycle, by front panel OUT button, Remote Analog or Digital
Communication command.
8. OVP programming accuracy % +/- 5% of Vo(rated)
9. OVP adjustment method --- Adjust by front panel Voltage encoder and Digital Communication command.
10. OVP trip point V 5% to 105% of Vo(rated) and shall always be greater than 105% of the Output voltage setting.
Default = 105% of Vo(rated)
11. OVP response time mS Less than 10mS for Output voltage to begin to drop.
12. Max. OVP reset time S 7 (from AC On/Off switch turn On)
13. Output Under Voltage limit --- Prevents adjusting Output voltage below limit.
Preset by the front panel or Digital Communication command.
0-95% of Vo(rated) and shall always be less than 95% of the Output voltage setting.
Raises the PS_OK signal when Vout is below limit.
Does not affect J1 Remote Analog programming.
Default = 0V.
14. Input Under Voltage protection --- Yes, power supply shutdown below AC Input low line (non-latching).
15. Over Temperature protection --- Unit shall shut down when internal temperature exceeds safe operating levels. (Latched in Safe-mode and
unlatched in Auto-mode).
16. Phase Loss Protection Yes, power supply shutdown after phase-loss detection (non-latching).

mS
Less than 3. Time for Vo to recover to within 2% of Vo(rated) for a load change of 50 to 100% or 100 to
of Io(rated).
5. Time for Output Stable S 2 maximum, from Enable Output until Output stable (within 2% of steady-state).
6. Output fall and rise --- Overshoot limited to 125% Rated Output. Voltage at No-Load, Full-Load, Resistive Load.
7. Start-Up delay S Less than 7 (without IEEE option installed)
Note: Items 2.5.1 through 2.5.7 with resistive load.
