The ABB UD/S4.315.2.1 is a high-performance 4-channel universal dimming actuator designed to deliver precise, flicker-free brightness control for modern and traditional lighting systems. Optimized for retrofit LED lamps (LEDi), it also offers broad compatibility with incandescent lamps, low-voltage halogen lights (paired with conventional/electronic transformers), 230V halogen lamps, and dimmable energy-saving halogen fixtures—making it ideal for mixed-load environments.
ABB UD/S4.315.2.1 equipped with automatic load detection, the actuator intelligently adapts to connected lighting types, eliminating the need for manual configuration while ensuring stable operation and extended component lifespan. Each channel supports a maximum 315W power output, catering to high-demand lighting setups, and features a dedicated neutral connection to enhance dimming smoothness, even for low-wattage loads (down to 2W). Compatible with KNX TP bus systems, it seamlessly integrates into smart building or home automation networks, enabling centralized control, scene programming, and synchronization with other KNX-enabled devices.
ABB UD/S4.315.2.1‘s compact DIN-rail mounting design (8 division units) and IP20 protection class ensure easy installation in control cabinets, saving space while ensuring durability for indoor applications. Additionally, it supports manual on-device operation for quick testing or emergency use, even without bus voltage, adding flexibility for on-site adjustments. Whether for retrofitting existing systems or new installations, the ABB UD/S4.315.2 combines versatility, high power, and smart integration to meet the dimming needs of commercial, residential, and industrial projects.
Commercial Spaces: Ideal for offices, retail stores, hotels, and conference centers—supports multi-zone dimming for mixed LED/halogen setups (e.g., display lighting, ambient lighting, meeting room fixtures) and integrates with KNX building automation systems for centralized control.
High-Power Lighting Zones: Suitable for large lobbies, exhibition halls, industrial workspaces, or auditoriums requiring high-wattage lighting (315W per channel) with precise brightness adjustment.
Retrofit Projects: Seamlessly upgrades existing lighting infrastructure (e.g., heritage buildings, older commercial properties) to support LEDs while retaining compatibility with traditional halogen/incandescent fixtures, avoiding full infrastructure replacement.
Premium Residential Installations: Perfect for luxury homes, villas, or home theaters with multi-room lighting systems—enables customized ambiance (e.g., mood lighting, task lighting) and integration with smart home KNX networks for scene programming.
Mixed-Load Environments: Excels in spaces using a combination of modern LEDs and traditional lamps (e.g., restaurants, museums) where consistent, reliable dimming across different load types is critical.
