Protection functions
Signal output
Overvoltage protection (OVP) Turns the output off, displays OVP, and lights ALM
Setting range 8 V to 89.6 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 ALM
Value (fixed) 96 V (120 % of the rated output voltage)
Overcurrent protection (OCP)
1
1 This does not protect against the discharge current peak that is generated from the capacitors inside
the PWX750ML output section when the load is changed suddenly.
Turns the output off, displays OCP, and lights ALM
Setting range 2.8 A to 31.36 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
Value 0 V to 84 V (0 % to 105% of the rated output voltage)
Overheat protection (OHP)
Turns the output off,
2
displays OHP, and lights ALM
2 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 protection 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.
Fan failure protection (FAN)
Turns the output off,
2
displays FAN, and lights ALM
Incorrect sensing connection
protection (SENSE) Turns the output off, displays SENS, and lights ALM
Low AC input protection
(AC-FAIL)
Turns the output off,
2
displays AC, and lights ALM
Shutdown (SD) Turns the output off, displays SD, and lights ALM
Power limit (POWER LIMIT) Lights ALM
Value (fixed) 787.5 W (approx. 105 % of the rated output power)
Communication monitoring
(WATCHDOG) Turns the output off, displays DOG, and lights ALM

1 J1 connector on the rear panel
Voltage monitor
(VMON) Selectable monitor voltage range: 0 V to 5 V or 0 V to 10 V
Setting
accuracy 2.5 % of rtg
Current monitor
(IMON) Selectable monitor voltage range: 0 V to 5 V or 0 V to 10 V
Setting

Status signal
output
1,2
2 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
