3-channel DALI LED dimmer for DIN-EN 60715 TH35 rail. Stand-by loss only 0.12 Watt. Suitable for controlling constant voltage (CV) LED modules 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 color. SwitchDim2: Operation via 2 pushbutton inputs allows control of brightness and color 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). Connecting current 16A. The maximum connected current can be distributed to 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, the operation can be done via two pushbutton 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 luminaires. The control is carried out via 2 DALI addresses, whereby the brightness is influenced via one address and the channel distribution (e.g.: color) via the other. The Colour&Dim mode allows the adjustment of the color without influencing the brightness and vice versa. The adjustment is done with DALI standard commands such as Dim Up/Down and can therefore be done with all common controllers and gateways (e.g.: KNX). This control option offers an alternative to the DT8-RGBWAF mode. Operable via DALI or SwitchDim2: DALI address 1, SwD1: brightness. DALI address 2, SwD2: Color.
