1-channel DALI LED dimmer for ceiling entry. Standby loss of only 0.12 watts. Suitable for controlling constant voltage LED modules (CV) with operating voltages from 12V to 48V. SW&Dim or SwitchDim2: Operation via 1 or 2 push-button inputs enables the control of brightness without DALI, alternatively corridor function for direct control with a motion detector. Dimming range 0.1%-100%. PWM-frequency switchable (122Hz/244Hz/488Hz/976Hz). Supply voltage 12V to 48V DC. Max. Connection current 16A. High efficiency. Configuration via PC software DALI cockpit and DALI USB interface. Operating modes: The output channel is controlled via a DALI address (Device Type 6). Alternatively, operation can be performed via one (SW&Dim) or two button inputs (SwitchDim2): SwD1,SW&Dim: Brightness. Short press: On/off. Long press: Dim. SwD2: Scene switch (short keystroke). If the SwD1 input is pressed for 2 minutes, the mode 'Corridor function' is changed. This operating mode remains active until the device
