3-channel DALI LED dimmer for luminaire installation and flush-mounted boxes. 59x33x15mm. Protection class IP20. Standby loss only 0.12 watts. Suitable for controlling constant voltage LED modules (CV) with operating voltages from 12V to 48V. DT6 operating mode: separate control of the channels via 3 DALI addresses. Colour&Dim operating mode: control via 2 DALI addresses, one for adjusting the brightness and one for adjusting the colour. SwitchDim2: operation via 2 button inputs enables control of brightness and colour without DALI. Dimming range 0.1%-100%. Switchable PWM frequency (122Hz/244Hz/488Hz/976Hz). Supply voltage from 12V to 48V DC (corresponding to the operating voltage of the LED modules). Connection current 8A. The maximum connected current can be distributed freely across the channels. High efficiency. Configuration via PC software DALI-Cockpit and DALI-USB interface. Operating modes: The device has several operating modes: DT6 (delivery status): In this operating mode, each channel is controlled via a separate DALI address (Device Type 6). Alternatively, operation can also be carried out via two button inputs (SwitchDim2): SwD1: Brightness. Short button press: On/Off. Long button press: Dimming. SwD2: Scene switch (short button press). Colour&Dim: This operating mode is used to control RGB lights. Control is via 2 DALI addresses, with one address influencing the brightness and the other the channel allocation (e.g. colour). The Colour&Dim mode enables the colour to be adjusted without affecting the brightness and vice versa. The adjustment is made using DALI standard commands such as Dim Up/Down and can therefore be carried out using all common controls and gateways (e.g. KNX). This control option offers an alternative to the DT8-RGBWAF mode. Can be operated via DALI or SwitchDim2: DALI address 1, SwD1: brightness. DALI address 2, SwD2: color.
