Notes
|
1. All parameters NOT specially mentioned are measured at 110V/230VAC input , rated load and
25℃of ambient temperature.
2. Ripple& noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with a
0.1uf &47uf parallel capacitor.
3. Tolerance:includes set us tolerance,line regulation and load regulation .

Question:
What is Dimming Operation for triac dimmable constant current led driver ?
Answer:
Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.Compatible with Leading edge or tailing edge triac dimmers.
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
