Product advantage:

•Dim-all: Triac

•Switch to PWM or Voltage Reduce output

•Dimming effect:

Voltage Reduce mode: 100%-0.01% dim, stepless dimming,flicker-free,

PWM dim mode:100-0.1% dim, flicker-free

•Triac dim mode: Forward phase & reverse phase, MLV, ELV dim

•Flexible wiring compartment to adjust the AC and DC wiring space

•Metal shell NEMA 4X for indoor and outdoor use; Wet, damp, and dry location

•Title 24 JA8 compliant

•Constant voltage type. 

•Super low loading request, works perfectly at 0.01-100% load.

7 years warranty

Dimming range: 100%-0.01% Ultra Deep Amplitude 

No Vpeak-peak during driver on/off and dimming, no harm to the LED for long-term use, and slow down the speed of lumen depreciation.

Works with single channel CCT warm-dim LED strip/tape (2 wires).

Switching different output mode can be compatible with more different types of LED lamps

compatible with DC-DC design LED fixtures, such as MR16, PAR, wall washer, linear lighting, LED strip/type

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 (-).  

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;
