■ Mechanical Specification 


Ø Input wire Black and White to be connected to AC L and N ,Green wire go ground,

Ø Output wire Red to LED Positive side (+) , Black  to LED Negative side (-).  

Ø Dimming cable DIM (+) Purple to 0/1-10V dimmer signal(+ ),DIM (-) Grey to 0/1-10V dimmer signal (-)  

Ø Please make sure your connect these correctly otherwise your product will not function correctly and could be damaged.


■ Connecting Diagram


Ø Using TRIAC/Phase cut dimming

1. The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a phase /Triac dimmer of lighting system.

2. Work with forward phase /leading edge ,MLV and reverse phase /trailing edge ,ELV,TRIAC dimmers.

3. Please try to use dimmers with power at least 1.5 times as the output power of the driver.



■Derating Curve



Ø To extend their life, please refer to the Derating Curve and derate according to the temperature.


■ Instruction:

Ø This driver should be installed by qualified and professional person;

Ø Please make sure the driver is installed with adequate ventilation around it to allow for heat dissipation.

Ø Ensure that wiring is correct before test in order to avoid light and power supply damage;

Ø If the dimmable LED drivers do not work normally, pl. don’t maintain privately, but contact us: [email protected]  Or take a phonecall: 0086-595-27256889
