UD/S4.315.2.1 ABB i-bus KNX LED-Dim Actuator 4-Fold 315 W MDRC Multichannel Dimmer Module for LEDi
The ABB i-bus KNX UD/S 4.315.2.1 is a four-channel multichannel universal dimming actuator developed around retrofit LED lamps (LEDi) but versatile enough for incandescent lamps, low-voltage halogen on conventional or electronic transformers, 230 V halogen lamps and dimmable energy-saving halogen lamps.
Each channel carries 315 W/VA, and outputs can be combined in groups when more power is needed on one circuit, giving up to 2 x 500 W/VA. Automatic load detection can be deactivated and a dedicated N terminal is provided per channel.
