If the wrong input is applied, the unit will not operate properly

and/or may be damaged.

Overcurrent protection circuit is built-in and comes into effect at

over 105% of the rated current.

Overcurrent protection prevents the unit from short circuit and

over current condition of less than 20 sec.

The unit automatically recovers when the fault condition is

cleared.
