DALI Dimmer 12/48 Vdc 1 Channel Multifunction

Description

The EK-GD2-DL-1-L-01 device is a very low voltage 12, 24 and 48Vdc PWM dimmer suitable for controlling LED strips and PWM dimmable LED loads.

The dimmer can be controlled via DALI1 or DALI2 bus, push-button control (N/O - normally open) at mains voltage or 12/24/48 V mains voltage, 0-10V or 1-10V analogue signal from an active actuator (which generates a variable voltage between 0 and 10V) or passive actuator, 47kΩ linear potentiometer or presence sensor.

The operating modes of the EK-GD2-DL-1-L-01 dimmer can be selected via onboard dip-switches.

Dimming

The graph shows the phenomenon of flickering 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.

Functions / Features

Dimmer with isolated push input, active and passive potentiometer / 0-10V / 1-10V, switch, sensor, phase cut, DALI2 DT6 and DALI2 DT6 high compatibility for voltage-current converters

Master/slave functionality

Programmable timed ignition

Menu for minimum dimming change, fade ON-OFF, curve type and frequency setup ('flicker-free') accessible via input button

Signalling LED for identifying correct power supply
