PART NAMES AND FUNCTIONS
1– Fuse: 3A (3/5A); 5A (10A)
2– Input power cable: 220VAC
Note
1– Store this unit in a dry well-ventilated and clean place.
2– Cut off input supply when maintenance.
3– Be careful to the heat when the power supply is high current outputing,pay attention to ven-
tilation.
4– Cauting: If this unit have any trouble,the output may rise over max. Rated voltage! Care for load
to prevent against damage.
