4-channel DALI LED dimmer for ceiling entry. Standby loss of only 0.12 watts. Suitable for controlling constant voltage LED modules (CV) with operating voltages from 12V to 48V. Operating mode DT6: Separate control of the channels via 4 DALI addresses. Color&Dim mode: Control via 2 DALI addresses, one for adjusting the brightness and one for adjusting the color. SwitchDim2: Operation via 2 button 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 (according to the operating voltage of the LED modules). Connection current 16A. The maximum connected current can be distributed to the channels as required. High efficiency. Configuration via PC software DALI cockpit and DALI USB interface. Operating modes: The device has several operating modes: DT6 (factory setting): In this operating mode, each channel is controlled by a separate DALI address (Device Type 6). Alternative
