1-channel DALI LED dimmer for ceiling installation 120x30x22mm. Protection class IP20. Standby loss 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 button inputs enables control of the 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 carried out via one (Sw&Dim) or two button inputs (SwitchDim2): SwD1, Sw&Dim: brightness. Short button press: on/off. Long button press: dimming. SwD2: scene switch (short button press). If the SwD1 input is pressed for 2 minutes, the device switches to corridor function mode. This operating mode remains active until the device is disconnected from the supply voltage (after power up: operation via SwD1/SwD2). Corridor function: mode with integrated staircase automation (e.g. for simple control with the relay contact of one or more motion detectors). When the input is pressed, the device is switched on to the maximum value. After the input signal drops, the brightness remains at this value for the duration of the hold time before it is reduced to the intermediate value. After the hold time for the intermediate value has elapsed, the device returns to the basic brightness value. When the input is activated again, the process starts again from the beginning. The 1-channel LED dimmer can be configured using the DALI cockpit software. Group membership can be specified and scene values and DALI parameters can be configured (the parameters displayed correspond to the delivery state). Delivery state: Before addressing for the first time, the device can be controlled using the group address G0. This preset group assignment is deleted during addressing, after which any group assignment can be made in the DALI cockpit. By sending a DALI reset command, the values defined in the DALI standard are restored.
