15W triac dimmable constant current led driver circuit Mechanical Specification:
Ø Input with Live Wire AC (L), Neutral Wire AC(N)
Ø Output LED SEC output Positive (LED+) , output negative(LED-). Connected to LED Lamps.
Ø Suggested wire diameter:Input 18-14AWG; Output: 20-14AWG
Note: Please make sure you connect these correctly otherwise your product will not function correctly and could be damaged
Derating Curve for constant current led driver circuit:
Dimming Operation Notice for 350ma led driver:
Ø 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.
Ø Usually matching with leading edge/Forward Phase Triac Dimmers( Can customized as a driver only matching trailing edge/reverse
phase Triac Dimmers if needed).
Ø Please try to use dimmers with power at least 3 times as the output power of the driver.
Ø for Forward phase,Magnetic low voltage and Triac Dimmers
