12v 24w constant voltage triac dimmable led power supply


The Triac dimmable led driver from Smarts is designed to power and Dim 24v constant voltage LED's via mains dimming. Hook up to a trailing edge dimmer and this led driver will allow the user to have excellent control over light levels dimming the mains power running into the driver. Tidy clean and simple Triac Dimming. We suggest loading the led driver for about 85-90 %for the most effective dimming.

 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
