The dimming range parameters adopted LUTRON dimming system as testing standards. The parameters may differ by using Triac/ELV dimming systems of different brands. We can customize program for clients’ high requirements. LUTRON is registered trademarks of Lutron Electronics Co., Inc. registered in the U.S. and other countries.


Over-heat Protection Shut down the output when PCB temp. 110°C.
Auto recovers when temp. back to normal.
Over Load Protection When O/P voltage exceed its range, O/P current declines.
Auto recovers when the load is reduced..
Short Circuit Protection Shut down automatically if short circuit occurs.
Auto recovers after faulty condition is removed..
Non-load Protection Auto detecting, auto recovers when load back to normal.
