| Input wire | Black(L) White(N) (2*18AWG) |
| Output wire | Red(V+) Black(V-) (2*22AWG) |
■ Dimming Operation and Connecting Diagram
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 10%
4. Please try to use dimmers with power at least 1.5 times as the output power of the driver.
