The Eelectron DM04A02KNX is a 4-channel universal KNX dimmer for 230 V loads with automatic load detection: each channel senses whether it is driving incandescent, halogen, transformer-fed or dimmable LED/CFL lamps and applies leading-edge or trailing-edge control accordingly. Adjacent channels (1+2, 3+4) can be linked to double the available power, so the device covers lighting from small LED spots to 600 W halogen groups.

It is intended for residential and hospitality panels where mixed lamp technologies must be dimmed reliably; the free DimmerLoadTester software helps verify LED compatibility before installation. The ETS application supports scenes, dimming curves, soft on/off, minimum and maximum levels, timers and status feedback, and the module must be mounted vertically for cooling.

Key Features

  • 4 universal dimming channels with automatic load detection (L leading edge / RC trailing edge)
  • Per channel: incandescent/halogen 300 W (RC); ferromagnetic transformers 200 VA (L); electronic transformers 60 VA (RC); dimmable LED 60 W (L) or 120 W (RC); LED drivers 60 W; CFL 60 W
  • Linked pairs 1+2 and 3+4: incandescent 600 W, ferromagnetic 400 VA, electronic transformer 100 VA, LED 100 W (L) / 200 W (RC), LED drivers 100 W, CFL 100 W
  • Scenes, dimming ramps, soft start/stop, level limits, timers and status objects in ETS
  • Overload, short-circuit and thermal protection with fault feedback
  • DimmerLoadTester software for checking LED lamp compatibility
  • Bus-powered (≤ 10 mA); 8-module PC-ABS DIN housing, vertical mounting
  • 250 group addresses / 250 associations
