DALI Dimmer 12/48 Vdc 4 Channels Multifunction

Description

The EKGD1-DL-4-L-01 DALI 2 standard 4-channel dimmer is powered by 12/24/48 Vdc with flicker-free PWM dimming and allows control of brightness, dynamic white (TW) and RGBW colour (DT6 and DT8) for low-voltage LEDs.

The inputs are DALI 2 bus type, compliant with the IEC 62386 standard.

The operating mode settings are made via a local dip-switch selector.

Dimming

The graph shows the flickering phenomenon as a function of frequency, measured across the entire dimming range. The results show the low-risk zone (yellow) and the zone with no observable effect (green). Defined by IEEE 1789-2015.
