Power supply for constant current LED modules

The DALI DT8 power supply for constant current LED modules with output currents up to 1100 mA from Lunatone allows independent control of brightness and color temperature. It comes in a user-friendly condition and is suitable for flush mounting. The dimming range is between 0.1 and 100%. The rated power is 20 watts.

In DT8 mode, brightness and color temperature are controlled via one DALI address (Device Type 8, Color Type Tc). In Balance & Dim mode, control takes place via 2 DALI addresses, one for adjusting the brightness and one for adjusting the channel distribution (e.g. color temperature). In Dim2Warm operating mode, there is one DALI address for dimming with simultaneous change of the color temperature. The SwitchDim2 operating mode allows operation via 2 button inputs and thus control of brightness and color temperature without DALI.

Protected against overtemperature/short circuit

The Lunatone DALI LED power supply has a switchable PWM frequency (122Hz / 244Hz / 488Hz / 976Hz) and a supply voltage of 230V AC. The configuration is done via the DALI-Cockpit software tool and the DALI USB interface. The power supply also has an overtemperature shutdown and integrated short-circuit protection.
