HED2040-A DALI Driver 1x40w

HED2040-A is a constant current & voltage 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 and voltage 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
