ABB KNX LED Dimming Actuator 4-fold 210W
- 4 independent dimming channels, each rated up to 210 W/VA. You can also parallel outputs for higher-wattage loads on fewer channels.
- It supports trailing-edge and leading-edge dimming for LED, halogen and incandescent lamps, plus inductive and electronic transformers. Automatic load-type detection can be switched off.
- You can operate every channel manually from the front panel. This works during commissioning or a bus failure, with no ETS download needed.
- Each channel has its own neutral connection and a 2 W minimum load.
- This is a genuine ABB product. Infinitex supplies it in Dubai with trade pricing, ETS product data and UAE-wide delivery.
The ABB KNX LED Dimming Actuator UD/S4.210.2.1 belongs to ABB’s current UD/S universal LED dimming actuator range. It sits on the DIN rail in the distribution board and takes its logic power from the KNX bus through an integrated bus coupler. As a result, it dims 4 channels of 230 V AC lighting.
What it does
- It offers 4 independent dimming channels, each rated up to 210 W/VA. You can also parallel outputs for higher-wattage loads on fewer channels.
- It supports trailing-edge and leading-edge dimming for LED, halogen and incandescent lamps, plus inductive and electronic transformers. In addition, automatic load-type detection switches off if needed.
- You can also operate every channel manually from the front panel. This works well during commissioning or a bus failure, and needs no ETS download.
- Each channel has its own neutral connection and a 2 W minimum load.
- This is a genuine ABB product. Infinitex supplies it in Dubai with trade pricing, ETS product data and UAE-wide delivery.
Where this ABB KNX LED Dimming Actuator fits
A 4-channel unit suits a mid-size apartment or several rooms sharing one distribution board. Because the KNX side is entirely software-defined, the same hardware covers LED, halogen and transformer-fed loads, you set the dimming curve and load type in ETS rather than choosing different hardware.
