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.
