Mechanical Specification

24V & 48V Version

1. Input wire 18AWG, Black and White to be connected to AC L and N,Green wire is ground wire and goes ground.
2. Output wire 4*16AWG, Red to LED Positive side (+), Black to LED Negative side (-).
3. Dimming cable 4*18AWG, DIM (+) Purple to 0/1-10V dimmer signal (+), DIM (-) Grey to 0/1-10V dimmer signal (-).
4. Please DO NOT connect “DIM-“ to “LED-“, “DIM+” to “ LED+”, or other incorrect connection.
5. Please make sure you connect these correctly otherwise your product will not function correctly and could be damaged.

Warm tips:

1. 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, we can customized.

Dimming Operation and Connecting Diagram

• 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;
  

• 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, MLV and Reverse phase, ELV, TRIAC dimmers or light system.
3. Min. loading is about 10%.
4. Please try to use dimmers with power at least 2 times as the output power of the driver.  

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

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; If the product is installed in a sealed lamp, it is recommended to reduce the load and use it; The recommended load size is ≤ 80% of the rated load.
3. Ensure that wiring is correct before test in order to avoid light and power supply damage.
4. If driver Cannot work normally, don’t maintain privately.
