LED Dimmer-actuator 4 channels RGBW

Code: EK-GC1-TP

TP1

KNX actuator for dimming and switching of low-voltage,

CV (constant voltage) LED sources. Suitable for applica-

tions in home and building automation KNX installations

Description

The ekinex

EK-GC1-TP dimming actuator is an S-mo-

de KNX rail mounting modular device for independent

switching and dimming of low-voltage (12...30 Vdc) LED

lighting devices in CV mode, with PWM modulation. The

typical application is with LED strips used for bulk lighting

or ambient scenic effects.

Outputs can be managed:

• as 4 independent channel (white or single color);

• as 2 channels, each used for a "dual white" strip (cold

and warm white tones);

• combined, as a single RGB (+W) color channel.

The device is equipped with an integrated bus communi-

cation module and is designed for rail mounting in distri-

bution boards and cabinets. For its operation, the device

receives command telegrams from the bus, sent by a

KNX device (such as a pushbutton, a sensor or another

switching or control device), that causes the switching or

the dimming of the lamp of the connected lighting devi-

ce. The manual operation of output channels is possible

through the membrane pushbuttons on the front of the

device. The device is powered by the KNX bus line with

SELV voltage 30 Vdc (for the logic section) and requires

a 12...30 Vdc auxiliary power supply, with adequeate cur-

rent capacity depending on the connected loads, to pro-

vide power for both the output loads and the power drive

section.

Note. The loads are low-side switched, i.e. they are

required to have a common-anode connection.
