Light dimmer module EK-GD2-DL-1-LV

Description
The DALI-2 1-channel dimmer EK-GD2-DL-1-LV provides brightness control for low-voltage LED sources (12–48 Vdc) using PWM dimming. It supports DALI-2 bus input compliant with IEC 62386 and offers dynamic white control (TW) via DALI DT8 with two independent channels (two DALI addresses) or as a single DT6 channel. Device functions and operating modes are selectable by a selector switch, allowing flexible integration in architectural lighting systems.

Technical data

• Device supply voltage: 10.8 Vdc (min) – 52.8 Vdc (max)
• Maximum output power: 240 W
• Control: DALI-2 bus or local push-button

The provided flicker analysis plots flicker versus frequency across the entire dimming range and highlights low-risk (yellow) and no-observable-effect (green) zones, in accordance with IEEE 1789-2015.
