Akubela KXAC-G1DC4 4-Gang Universal KNX Dimming Module

Akubela KXAC-G1DC4 4-Gang Universal KNX Dimming Module

The Akubela KXAC-G1DC4 is a DIN rail-mounted lighting actuator built for KNX-based home and building automation projects. Listed on the official KNX Association certified products register under Akubela Co., Ltd. as the 4 Gang Universal Dimming Module, it gives integrators four independently controlled dimming channels from a single compact device, making it a practical choice for switchboards where panel space is limited but flexible lighting control is required.

Key Features

• Four independent dimming outputs on one DIN rail module, ideal for consolidating lighting circuits in a single enclosure
• Universal dimming principle designed to handle common resistive, inductive and capacitive (RLC) lighting loads alongside dimmable LED drivers
• Standard KNX bus communication for seamless integration with ETS-programmed systems and third-party KNX devices
• Scene and preset storage so each channel can recall pre-set brightness levels on command
• Manual/local override control for testing and commissioning without needing a live bus connection
• Status feedback objects that report channel switch state and brightness back to the KNX bus
• Bus voltage monitoring and fault reporting to help installers diagnose wiring or load issues quickly
• Compact DIN rail housing that mounts into standard distribution boards alongside other Akubela KNX add-on modules

Typical Applications

This module suits residential and light commercial projects where a KNX system already governs lighting, climate, or shading, and a dedicated dimming actuator is needed for a specific board or zone. It's commonly paired with Akubela switch panels, scene buttons, or the Akubela HyPanel range so that dimmed lighting circuits can be triggered from wall panels, schedules, or whole-home automation scenes. Electricians retrofitting older switchboards with smart dimming, or new-build integrators standardising on a KNX backbone, will find the universal load compatibility reduces the guesswork around which dimmer to specify for a given fitting.

Frequently Asked Questions

Does this module need an Akubela hub to work?
No. As a standard KNX device it is configured through ETS software and communicates directly over the KNX bus, so it will work in any properly designed KNX installation, not just Akubela-branded systems.

Can each of the four channels be programmed separately?
Yes, each of the four dimming outputs is addressed and configured independently in ETS, allowing different scenes, presets and load behaviour per channel.

What kind of lighting loads is it designed for?
It is built as a universal dimming actuator intended for common dimmable lighting loads found in residential and commercial fit-outs, including LED drivers. Always confirm specific load compatibility and channel power limits against the manufacturer's datasheet before final circuit design.
