¡ö?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.
