Mechanical Specification
Input with AC (L), (N)
Output cord: （DIM+）（DIM-）
Derating Curve
Load carried in accordance with the load derating curve, according to the ambient temperature derating, in order to extend the service life
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 dimmers, which have access to a wider dimming range, high-power dimmer is difficult to achieve the output current to zero
