Brightness then you could operate with the other dimming; ¡ùUsing 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 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 as the output power of the driver.
