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 connecting 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 the output power of the driver.
