4-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 4 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 8 A. The maximum connection current can be distributed among the channels as desired. High efficiency. Configuration via PC software DALI-Cockpit and DALI-USB interface. Operating modes: The device has several operating modes: DT6 (delivery state): 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.
