Output shut down when power supply changes from CV to CC mode, manual reset by front panel OUT
button or Digital Communication, user-selectable.
S
Min = 0.25/Max = 25, Default = 0.25
Settable via "FBD" command using Digital Communication command.
---
Inverter shut-down, manual reset by AC input recycle, by front panel OUT button, Remote Analog or Digital
Communication command.
%
+/- 5% of Vo(rated)
---
Adjust by front panel Voltage encoder and Digital Communication command.
V
5% to 105% of Vo(rated) and shall always be greater than 105% of the Output voltage setting.
Default = 105% of Vo(rated)
mS
Less than 10mS for Output voltage to begin to drop.
S
7 (from AC On/Off switch turn On)

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.
---
Yes, power supply shutdown below AC Input low line (non-latching).
---
Unit shall shut down when internal temperature exceeds safe operating levels. (Latched in Safe-mode and
unlatched in Auto-mode).
Yes, power supply shutdown after phase-loss detection (non-latching).
