LED Dimmer LED-04B-ANA-DALI

Analog LED Dimmer - non-PWM - via the DALI protocol. 4 independent constant current outputs, CC (constant current) 250mA to 1400mA. Dimming 0-100% high resolution, monochrome coloured or circadian/HCL (Human Centric Lighting warm white/cold white).

Quick Facts

  • 4 dimming channels 250mA to 1400mA
  • dimming 0-100%
  • protocol DALI
  • analog dimming (amplitude dimming)
  • planetarium
  • theater
  • museum, gallery, exhibition

The non-PWM LED Dimmer was developed for absolutely flicker and flicker-free dimming of constant current controlled LEDs or LED lights. It dims absolutely without pulse width modulation and is a purely linear dimmer. It is possible to perfectly control the brightness of the LEDs between 0% and 100% with a dimming resolution of 16 bit (internal resolution in ISYGLT operation). The minimum brightness of the LED Dimmer per channel can be adjusted on the device and thus optimally adapted to the LEDs to be controlled.

Depending on configuration and LED type, this dimmer can control LEDs with a total of 300W (4x 75W) power.

Recommended areas of use are all areas in which healthy lighting is ensured, as the effects of conventional PWM dimming have not been fully investigated, but are classified by experts as posing a health risk. PWM is used as standard in all previous LED Dimmers, including the DALI and KNX/EIB standards. Therefore, the use of non-PWM dimming is particularly recommended in areas where people stay longer or where high demands are placed on lighting quality:

  • planetarium
  • theater
  • museum, gallery, exhibition
  • clinic and nursing home
  • office and other workplaces
  • school and educational institution
  • hotel and conference room
  • shopping centre and shop


The LED-04B-ANA-DALI is controlled via the standard DALI protocol.

Notice: After changing the DIP switches, the DALI addresses of the LED dimmer must be deleted again. This must then be reparameterized in the current configuration.

Set minimum dimming values

A potentiometer and a button are available for setting the minimum dimming values.

The dimming channels must be active before setting - dimming values >= #1

DIP switches 9-12 are used to select the channels to be set (see table below). The setting can be made separately for each channel or for several channels at the same time.

As soon as one or more DIP switches are set to ON, the relevant channels are set to DALI dimming value #1 and the potentiometer value is output. The minimum value threshold can be adjusted by turning the potentiometer. The potentiometer is updated every 0.5 seconds.

If the "S2" key is pressed for longer than 3 seconds, the current minimum value is saved. This is indicated by 3 blinks of the yellow LED.
