Light dimmer module EK-GD2-DL-1-L-01

Description
The EK-GD2-DL-1-L-01 is a very low-voltage PWM dimmer designed for controlling single-colour LED strips and PWM-dimmable LED loads. It supports 12 Vdc, 24 Vdc and 48 Vdc supplies (operating range 8 Vdc–53 Vdc) and offers multiple control interfaces. Operating modes are selectable via onboard dip-switches.

Control options

• DALI1 or DALI2 bus
• Push-button control (N/O) at mains voltage or 12/24/48 V
• 0–10 V or 1–10 V analogue signal (active or passive actuator)
• 47 kΩ linear potentiometer
• Presence sensor
