Dimming Operation
1. Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
2. Compatible with Leading edge or tailing edge triac dimmers.
3. please try to use the small power dimmer, have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero.
