Notes1. All parameters if NOT specially mentioned are measured at 120VAC input , rated load and 25℃of ambient temperature.
2. To extend the driver's using life ,please reduce the loading at lower input voltage.


Derating Curve

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



Mechanical Specification 


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

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

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

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

Note: Any other requests we can customized. 


Connecting Diagram

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.

 Instruction:


1)This driver should be installed by qualified and professional person;

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

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