Light dimmer module EK-GD1-DL-4-L-01

Description
The EK-GD1-DL-4-L-01 is a DALI 2 standard 4-channel dimmer powered by 12/24/48 Vdc. It provides flicker-optimized PWM dimming for low-voltage LED installations and supports brightness control, Tunable White (TW) and RGB/RGBW colour control (DT6 and DT8) via DALI 2 bus inputs compliant with IEC 62386. Operating modes are set locally using a dip-switch selector, making the unit suitable for integration in architectural lighting systems.

Technical data
Inputs

• Constant input voltages: 12 Vdc, 24 Vdc, 48 Vdc
• Supply voltage operating range: 8 ÷ 53 Vdc

Outputs

• Number of outputs: 4 PWM channels
• PWM output voltage: 12/24/48 Vdc
• Supported load types: single colour, Tunable White (TW), RGB, RGBW (DT6 and DT8)
• Output current per channel: 0 A ÷ 8 A
• Single-channel mode output current: up to 32 A (max. 1536 W @48 Vdc)
• Nominal output power per channel: 96 W (@12 Vdc), 192 W (@24 Vdc), 384 W (@48 Vdc)

Control

• Control interfaces: DALI2 DT6/DT8, 0-10V / 1-10V (active/passive), PUSH, linear potentiometer, switch, sensor, phase cut, DMX512A-RDM, BLE

Notes on flicker
Flicker behaviour has been characterised across the full dimming range. Results indicate low-risk and no-observable-effect zones according to IEEE 1789-2015 guidance; consult the device data for frequency-specific performance.
