Rotary dimmer for controlling DALI ballasts (EVG). For lights with DALI Device Type 8 for Tunable White in accordance with IEC 62386-209, the light color can also be set. Dimmer for active and passive operation: -active operation: when connected to the mains voltage, the dimmer supplies the control current for max. 26 DALI participants. Passive operation: without a connection to the mains voltage, the dimmer supplies itself with the DALI voltage and serves as an additional control point. Parallel connection of max. 4 active dimmers to supply max. 104 DALI participants is possible. With claw and screw fastening. With screw terminals. Functions: Switching and dimming DALI lights - adjustable color temperature (for lights with DALI Device Type 8 for Tunable White in accordance with IEC 62386-209) - adjustable color temperature limit values - adjustable basic brightness - adjustable switch-on brightness - active and passive operation possible. Nominal voltage: AC 230 V, 50/60 Hz. Power consumption: max. 2 W. Nominal voltage DALI: DC 16 V (typical). Output current DALI: max. 52 mA. Color temperature setting: 2000 to 10000 K. Connection terminals: screw terminals for max. 4 mm2 (single-wire). Ambient temperature: -5 degrees C to + 45 degrees C. Type: DM51440.
