Sensor / Dim-actuator combination,
The SIENNA SAMDR sensor / actuator has an 230V input and a Triac switched output (leading-edge) for ohmic loads up to 300W. Loads up to 150W are allowed when the actuator is used with universal electronic transformers. In overload conditions, the actuator switches off automatically and can be activated only after a predefined cooling phase of 60s. Compatible with LEDs that are designed to work with leading-edge dimmers.
