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.
