Output mode selection | When the blue&white wire and the yellow&gray wire at the output terminal are short-circuited, it indicates the Pulse-Width Modulation (PWM) mode. When they are disconnected, it indicates the Voltage Regulation (VR) mode of direct current voltage modulation. | ||||
Switching the output mode requires the power to be cut off for 3 seconds and then powered on again for the mode switching to take effect. | |||||

Remarks: |
Warm tips:
1. Recommended Max. Carrying Current (A) = wire diameter(mm²) x 10A/mm ²
For example: 1mm ² output cable, Recommended Max. Carrying Current (A) = 1mm ² x 10A/mm ²=10A
2. Any other requests for cable, we can customized.
Dimming Operation
Using two ways of dimming at the same time, you must be assured that LED lighting is up to the max. Brightness then you could operate with the other dimming;
l Using one dimming ---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 or lighting system.
2. Working with forward phase /leading edge, MLV and Reverse phase /trailing edge, ELV, TRIAC dimmers or light system.
3. Min. loading is about 20%
4. Please try to use dimmers with power at least 1.5 times as the output power of the driver.

Using one dimming ---0-10/ 1-10V/ 10V PWM/ Potentiometer dimming
