LED Dimmer LED-04B-ANA-DMX

Analog LED Dimmer - non-PWM - with 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 ISYGLT or DMX512 8/16-bit
  • analog dimming (amplitude dimming)
  • healthy LED light without PWM
  • perfectly suitable for TV cameras

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 academic institution
  • Hotel and conference room
  • Shopping centre and shop

The LED Dimmer can be operated either on the ISYGLT-BUS or DMX512-BUS.

The following functions can be performed independently by the LED Dimmer:

  • Calculation of rise times from 0.5 seconds to 12 hours
  • Fidelity colour dimming by specifying the colour over the entire brightness range
  • Colour temperature control (colour mixing) for 2 areas with 1x cold white and 1x warm white
  • Autonomous movement from current ACTUAL values to preset SET values at a preset speed (optional in preset time)
  • Feedback "Set value reached" after execution of time functions
  • Stop function during execution of time functions
  • OVERSAMPLING error correction: With the so-called "OVERSAMPLING", the module automatically corrects the jumps in dimming values caused by the cycle times of the BUS system. For this purpose, the dimming values between the BUS cycles are transformed back into the resolution of 16 bits by linearisation. This prevents, for example, flickering when controlling dimmers. During programming, the OVERSAMPLING is referred to as the SOFT function.
  • Execution of blinking functions
  • Adaptation to various LED modules
  • Calculation of defined and definable curves
  • Calculation of the min. and max. settings per channel to use the full 16-bit width
  • Complex emergency mode function
