45W triac dimmable constant voltage LED driver Mechanical Specification
- Input Brown with AC (L),Blue with AC(N)
- Output Red is(DIM+),Black is(DIM-)
- Note: Any other requests we can customized.
Dimming Operation
- 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
We can supply you ETL approved Junction boxes for all kinds of the LED drivers
