Homira KNX 4-fold General Dimming Actuator

The Homira KNX 4-fold General Dimming Actuator (HM-DI-04.3) is a high-performance multifunctional dimmer designed for controlling four independent lighting channels. Each channel supports up to 300 W (R/L/C/LED) loads with automatic load-type detection to ensure smooth and flicker-free dimming. The device offers customizable dimming curves, soft on/off, staircase and night mode, and fault protection for over-temperature and short circuits. Advanced features include scene and logic functions, forced operation, status feedback, timer (delay, flashing, cyclic), and current detection for energy monitoring. Configurable via ETS 5 or higher, it is suitable for resistive, inductive, capacitive, and LED lighting loads, providing stable and precise dimming control for residential and commercial KNX lighting applications.
