ITR501-0004 | Interra KNX 4-Channel Universal Dimmer Actuator (4x 250W)
The Interra KNX 4-Channel Universal Dimmer Actuator (ITR501-0004) is a high-density dimming module providing four independent channels, each capable of delivering 250W of output power (1000W total). As a universal dimming solution, it expertly drives a comprehensive range of load types (R, L, and C) to accommodate both modern and conventional lighting fixtures.This actuator features automatic detection and management for diverse loads, including incandescent lamps, low and high-voltage halogen lamps, and dimmable LED retrofit lamps and compact fluorescent lamps. For precision lighting control, the dimming curve can be customized by dividing it into five separate zones, with independent adjustable dimming speeds for each zone.Safety and reliability are ensured through integrated features like temperature protection, short circuit protection, and error notification via channel LEDs. The actuator also allows for manual control and supports programming via ETS without the need for a 230 V supply voltage. Its ability to handle 3-phase systems with separate phase and neutral connections per channel makes it exceptionally flexible for complex commercial or large residential wiring.
