4 channels DALI LED dimmer for ceiling installation 120x30x22mm. 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 DT6: separate control of channels via 4 DALI addresses. Operating mode Colour&Dim: activated by 2 DALI addresses, one to adjust brightness and one to set the colour. SwitchDim2: operation via 2 pushbutton inputs permits control of brightness and colour without DALI. Dimming range 0.1%-100%. Switchable PWM frequency (122Hz/244Hz/488Hz/976Hz). Power supply from 12V to 48V DC (depending on operating voltage of LED modules). Connected current 16A. The maximum connected current can be distributed to any channel. High efficiency. Configuration via DALI Cockpit PC software and DALI USB interface. Operating modes: The device has several operating modes: DT6 (as-delivered state): In this operating mode each channel is controlled by a separate DALI address (Device Type 6). Alternatively, operation can also take place by two pushbutton inputs (SwitchDim2): SwD1: brightness. Press pushbutton briefly: On/Off. Press pushbutton long: Dim. SwD2: Scene switch (press pushbutton briefly). 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.
