■ Dimming Operation and Connecting Diagram
窗体顶端
※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 connecting a phase /Triac dimmer of lighting system.
2.Working with forward phase /leading edge , MLV and Reverse phase /trailing edge , ELV, TRIAC dimmers
3.Min loading is about 10%
4. Please try to use dimmers with power at least 1.5 times the output power of the driver.
