¡ù?Input (L) and (N) with wires to be connected AC.
¡ù Output ?LED SEC :(LED+) (LED-)
Dimming Operation
n?Output constant current level can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
n?Compatible with Leading edge or tailing edge triac dimmers.
n?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
