Overvoltage protection (OVP)
Turns the output off, displays OVP, and lights ALARM
Setting range
3 V to 33.6 V
8 V to 89.6 V
23 V to 257.6 V
65 V to 728.0 V
(10 % to 112 % of the rated output voltage)
Setting accuracy
±(1.5 % of rtg)
Overvoltage protection 2 (OVP2)
Turns the output off, displays OVP2, and lights ALARM
Value (fixed)
36 V
96 V
276 V
780 V
(120 % of the rated output voltage)
Overcurrent protection (OCP)

1
This does not protect against the discharge current peak that is generated from the capacitors inside the PWX output
section when the load is changed suddenly.
Turns the output off, displays OCP, and lights ALARM
Setting range
7.5 A to 84 A
2.8 A to 31.36 A
1 A to 11.2 A
0.35 A to 3.92 A
(10 % to 112 % of the rated output current)
Setting accuracy
±(3 % of rtg)
Undervoltage limit (UVL)
Cannot be set to a value less than or equal to the set voltage
Setting range
0 V to 31.5 V
0 V to 84 V
0 V to 241.5 V
0 V to 682.5 V
(0 % to 105 % of the rated output voltage)
Overheat protection (OHP)
Turns the output off

Use the CONFIG settings to specify what happens when a protection function is activated and the output is turned
off. You can select to turn the output on automatically when the problem that caused the alarm is fixed (CF03: Auto)
or to leave the output turned off when the problem that caused the alarm is fixed (CF03:SAFE). The specified protec-
tion operation is the same for the OHP, FAN, and AC-FAIL alarms. You cannot make separate settings for the OHP,
FAN, and AC-FAIL alarms.
Overheat protection2 (OHP2)
Turns the output off, displays OHP2, and lights ALARM
Fan failure protection (FAN)
Turns the output off
, displays FAN, and lights ALARM
Incorrect sensing connection pro-
tection (SENSE)
Turns the output off, displays SENS, and lights ALARM
Low AC input protection (AC-FAIL) Turns the output off
, displays AC, and lights ALARM
Shutdown (SD)
Turns the output off, displays SD, and lights ALARM
Power limit (POWER LIMIT)
Lights ALARM
Value (fixed)
787.5 W (approx. 105 % of the rated output power)
Communication monitoring
(WATCHDOG)
Turns the output off, displays DOG, and lights ALARM

Photocoupler open collector output;
maximum voltage 30 V, maximum current (sink) 8 mA; isolated from the output and control circuits; status commons
are floating (withstand voltage of less than or equal to 60 V); and status signals are not mutually isolated.
OUTON STATUS
Turns on when the output is on
CV STATUS
Turns on during CV operation
CC STATUS
Turns on during CC operation
ALM STATUS
Turns on when an alarm has been activated
PWR ON STATUS
Turns on when the power is turned on
