7-3 Output Over Current Protection Function
Output voltage will be lowered when output current is in state of over current and start operating over current
protection circuit. (Over current protection set point : 105 to 250% of rating current value)
It will automatically recover when over current state is released. In order to avoid from damage, please do not hold
the over current state for more than 30sec.
If by any reason does not auto recover after releasing, please off the output at ON/OFF control or switch off to
reactivate.
7-4 Low Input Voltage Protection Function

7-5 Input Circuit Protection Function
Fuse is built in at input in order to protect circuit at secondary side when overcurrent flows to input by some
abnormalities.
Rating current and fusing current of the Built-in fuse is as below table. To assure fusing at abnormality, current
capacity of power supply should be more than fusing current which is stated in below table.
