Akubela KXAC-G1DD4 Dual-Channel KNX to DALI Gateway

Akubela KXAC-G1DD4 Dual-Channel KNX to DALI Gateway

The Akubela KXAC-G1DD4 is a DIN rail mounted interface that links a KNX building automation bus to two independent DALI lighting channels. It gives integrators a compact way to bring DALI-based dimming, colour temperature adjustment and RGB colour control into a standard KNX/ETS project, making it well suited to commercial fit-outs, hospitality lighting and higher-end residential smart lighting installations.

Key Features

• Two independent DALI channels, each capable of addressing up to 64 DALI devices for a combined capacity of 128 luminaires or drivers
• Support for DALI device types DT6, DT8 Tc, DT8 XY and DT8 RGB, covering dimming, tunable white and full colour lighting
• Integrated DALI bus power supply built into the gateway, removing the need for a separate DALI PSU on each line
• Wide operating voltage range: 21-30VDC on the KNX bus and 100-240VAC, 50/60Hz mains input for the DALI side
• Low standby and running power draw, helping keep switchboard heat and energy use down
• Compact enclosure sized 90.1 x 72 x 66.4mm for tidy mounting on a standard 35mm DIN rail
• Wide environmental tolerance with operation from -5°C to 45°C and up to 93% relative humidity (non-condensing)
• Full support for DALI groups and scene programming, configured through the KNX ETS tool
• Backed by a 2-year warranty for peace of mind on commercial installs

Where It Fits in a Project

This gateway is intended for electricians and system integrators who need to control DALI-compatible LED drivers, downlights and ballasts from an existing or new KNX installation. Typical applications include open-plan offices, hotel corridors and function rooms, retail fit-outs and larger homes where lighting scenes, group dimming and colour temperature changes are managed centrally alongside blinds, HVAC and other KNX devices. Because each of the two channels operates independently, the unit can serve two separate lighting zones or floors from a single DIN rail module.

Frequently Asked Questions

How many lights can one gateway control?
Each of the two channels supports up to 64 DALI devices, giving a total addressable capacity of 128 luminaires or drivers across both channels.

Do I need special software to set it up?
Yes, the gateway is commissioned using standard KNX ETS software, where DALI groups, scenes and device types are configured against KNX group addresses.

Can it control colour and colour temperature, not just dimming?
Yes, the gateway supports DALI device types DT8 Tc, DT8 XY and DT8 RGB in addition to standard DT6 dimming, so tunable white and RGB colour fixtures can be managed from KNX.
