Overvoltage protection(OVP)
Turns off the load at 110% of the rated voltage
Overcurrent protection(OCP)
0.03 ~ 38.5A 0.06A ~ 77A 0.2A ~ 231A
or 110% of the maximum current of each range
Load off or limit selectable
Overpower protection(OPP)
0.1W ~ 192.5W 0.3W ~ 385W 1W ~ 1155W
or 110% of the maximum power of each range
Load off or limit selectable
Overheat protection(OHP)
Turns off the load when the heat sink temperature reaches 95 °C
Undervoltage protection(UVP)
Turns off the load when detected. Can be set in the range of 0 V to
150 V or Off.
Reverse voltage protection(RVP)
By diode. Turns off the load when an alarm occurs.
Rating overcurrent protection (R.OCP)
An R.OCP message will be produced when the input current range is
greater than 110% of the rated operating current range (I range).
