12v 48w class2 triac dimmable led driver with junction box
Mechanical Specification for class 2 dimmable led driver:
Input (L) and (N) with wires to be connected AC.
Output LED SEC :(LED+) (LED-)
Dimming Operation
The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
Usually matching with leading edge Triac Dimmers( Can customized as a driver only matching trailing edge Triac Dimmers if needed).
Please try to use dimmers with power at least 2.5 times as the output power of the driver.
for Forward phase,Magnetic low voltage and Triac Dimmers
