DALI LED dimmer with RGB colour control for luminary installation and flush-mounted box. 59x33x15mm. Protection class IP20. Only 0.12 watt standby loss. Designed to control constant voltage LED modules (CV) at operating voltages of 12V to 48V, operating mode DT8: a DALI address to control brightness and colour DALI DT8, Type RGBWAF). Operating mode Colour&Dim: activated by 2 DALI addresses, one to adjust brightness and one to set the colour. SwitchDim2: Operation via 2 switch inputs permit brightness and colour to be controlled without DALI. Dimming range 0.1%-100%. Switchable PWM frequency (122Hz/244Hz/488Hz/976Hz). Power voltage 12V to 48V DC (depending on operating voltage of LED modules). Connected current 8A. The maximum connected current can be distributed to the channels as required. Low stand-by losses. High efficiency. Configuration via DALI Cockpit PC software and DALI USB interface. Operating modes: The device has several operating modes: DT8 (as-delivered state): In this operating mode brightness and colour are controlled by a DALI address (Device Type 8). Alternatively, operation can also take place by two pushbutton inputs (SwitchDim2): SwD1: brightness. Press pushbutton briefly: On/Off. Press pushbutton long: Dim. SwD2: Colour. Colour&Dim: This operating mode is used to control RGB luminaries. Control is by means of 2 DALI addresses. One address affects brightness and the other affects channel distribution (e.g.: colour). Colour&Dim mode is used to adjust colour temperature without affecting brightness and vice versa. Adjustment is by means of DALI standard commands such as Dim Up/Down. This permits all customary controls and gateways (e.g. KNX). This control option is an alternative to DT8-RGBWAF mode. Operable via DALI or SwitchDim2: DALI address 1, SwD1: brightness. DALI address 2, SwD2: Colour.
