[HED2050-A] – Constant Current DALI LED Driver (1*50W)


Product Introduction 

HED2050-A  is a constant current Dali LED driver. It also offer other dimming options like 1-10V dimming and Switch-Dim.  It has a built in DIP switch which allows easy multiple LED current selection options. Some of the product highlights are :

  • Automatic output reduction 80%–60%–40% against overheat
  • Failure DALI feedback
  • Flicker-free dimming from 100%~30%
  • In compliance with DALI 2 standard
  • DALI and switch-Dim can be used at the same time
