Description
Introduction
The theben SU 1 DALI-2 (item number 4940091) is a flush-mounted 1-way DALI-2 switching actuator engineered for the control of standard 230 V AC mains voltage equipment. Designed for versatile integration, this compact actuator effectively manages loads such as lighting fixtures, ventilation fans, and circulation pumps. This device is part of our KNX system devices range.
In addition to standard 230 V AC mains load control, the unit is suited for extra-low voltage applications and for integration with higher-level building management networks, including HVAC control systems. Its flush-mounted design allows for easy installation directly into electrical back boxes.
