The Eelectron DM01D01KNX is a 1-channel universal KNX dimmer rated 700 W, built for the large incandescent, halogen, transformer-fed and 230 V LED loads that ordinary 2- or 4-channel dimmers cannot carry. It recognizes the load automatically and selects leading-edge (L) or trailing-edge (RC) phase control, and it detects 50 or 60 Hz mains on its own.
Up to two DM01D01ACC slave modules connect to the master over a 2-wire local bus (max 2 m between modules), each adding another 700 W channel on the same KNX address; channels may sit on different phases. The ETS application covers scenes, dimming curves, soft start/stop, minimum/maximum levels, timers and status feedback. Thermal derating is managed internally and the datasheet gives the load curve above 35 °C.
