Dimming Operation

  • The Pulse-Width Modulation (PWM) of output voltage can be adjusted through input terminal of the AC phase line(L) by connection a triac dimmer.
  • Usually matching with leading edge Triac Dimmers( Can customized as a driver only matching trailing edge Triac Dimmers if needed).
  • Please try to use dimmers with power at least 2.5 times as the output power of the driver.
  • for Forward phase,Magnetic low voltage and Triac Dimmers


  • Prevent to reverse polarity;
  • Risk of Electric Shock. When used outdoors, install only on a circuit protected by a Class A GFCI;
  • Risk of Fire. Installation involves special wiring methods to run wiring through a building structure. Consult a qualified electrician;
  • Risk of Electric Shock. Mount the unit at a height greater than 1 foot from the ground surface.
