Bluetooth-controlled digital phase-cut dimmer for mounting on DIN rail. Can be used for TW LEDDim, regulation of light or straightforward ON/OFF; this is set via the SG Smart app. The LEDDim Smart DIN 1000 can be controlled via two inputs. P1 is for a rocker switch, either 230V or 24V. The P2 is for simple ON/OFF PIR sensor control, where the output phase from the sensor connects to the P2 input. The antenna ensures good Bluetooth connection.
