Akubela KXAC-B1DV4 4-Channel KNX 0-10V Dimming Module

Akubela KXAC-B1DV4 4-Channel KNX 0-10V Dimming Module

The Akubela KXAC-B1DV4 is a DIN rail-mounted KNX actuator that converts standard KNX bus telegrams into four independent 0-10V analogue dimming outputs. Built for professional and residential lighting projects, it lets integrators drive dimmable LED drivers and ballasts directly from a KNX installation, with full support for switching, dimming, scene recall, and staircase timing behaviours configured through ETS.

Key Features

• Four independent 0-10V analogue outputs, each rated up to 100mA, for controlling dimmable drivers and ballasts
• Supports switch, relative, and absolute dimming modes for flexible control strategies
• Built-in scene and preset functionality so each channel can recall pre-set brightness levels
• Dedicated stair light (staircase) mode that automatically times out and fades lighting off
• Manual override buttons on the module for local dimming and testing without a bus connection
• Bus reset function and continuous status/error reporting back to the KNX system
• Bus-powered design (21-30V DC) drawing under 12mA, removing the need for a separate power supply
• Compact IP20 housing for standard 35mm DIN rail mounting inside distribution boards

Typical Applications

This module suits offices, hotels, retail fitouts, and homes where dimmable LED drivers, fluorescent ballasts, or other 0-10V compatible fixtures need to be integrated into a wider KNX lighting control scheme. Because each of the four channels operates independently, a single KXAC-B1DV4 can manage separate zones or fixture groups from one DIN rail location, with scene changes and staircase-style automatic-off timing configured entirely in ETS to suit the site's lighting design.

Frequently Asked Questions

Does the KXAC-B1DV4 need its own power supply?
No. The module is powered directly from the KNX bus, drawing a small current, so no auxiliary mains supply is required for the KNX side of the device.

Can each channel be dimmed to a different level?
Yes. The four outputs are fully independent, so each can be switched, dimmed, or assigned to its own scenes and staircase timing via ETS.

What kind of fixtures can this module control?
It is designed for lighting drivers and ballasts that accept a standard 0-10V analogue dimming signal, commonly used with dimmable LED drivers and some fluorescent control gear.
