Main features

lSoft switch technology, high efficiency, small size

lInput over/under voltage protection function

lNatural cooling and over temperature protection function

lConverse connection protection function, over current, short circuit protection

Protection functions

lOutput current limit protection: the max output current is limited to the rated output current.

lOver temperature protection: the converter shuts down once the temperature exceed the threshold and resume to work after the temperature comes lower.

lOutput over voltage protection: the converter shuts down automatically once the output voltage exceeds the threshold.

lShort circuit protection: the current output is shown as fig. 1. Once output short circuit, the output voltage will be dropped to 0 immediately and the output current will be restrained less than 15% of rated current. The power module can keep undamaged under short circuit and resume to work after troubleshooting.
