The successful and reliable Universal Dimmer UD-700-X2 is now also available with DALI interface. All dimmable light sources (e.g. dimmable LED lamps) can be perfectly dimmed with it. It requires no minimum load and dims flicker-free starting from just one LED retrofit lamp. Even a large number of LEDs is no problem for the dimmer.
The Universal Dimmer with DALI interface is suitable for the reliable operation of high-voltage lamps, magnetic transformers, electronic transformers, ESL and LED retrofit lamps. There are 2 separate dimmer outputs available, each of which can be loaded with 700W. By configuration and parallel connection of the outputs the dimmer is loadable with 1x1400W.
Each channel can be parameterised separately for the corresponding load type (leading edge/trailing edge mode). The dimmer automatically checks the connected load by carrying out a short test after first applying the operating voltage to check whether the connected load can be operated with the desired setting.
The dimmer operates with an internal dimming resolution of 16 bits and thus meets the highest demands.
The factory-set properties such as dimming curves, minimum and maximum limits can be changed and optimised by the user himself.
Control modes of the dimmer:
- DALI
- standalone: 0-10V, 1-10V, push-button (single-button dimmer)
- internal potentiometers
- to the DALI interface, the internal potentiometers and voltage inputs can be parameterised as priority, merge operation or for the BUS failure.
A free software tool is available for DALI and standalone users. This allows the dimmer to be optimised per parameter via USB or RS-485 data connection and internal data such as temperatures, voltages, peak currents and power to be displayed. An oscilloscope function is also integrated as a new feature. For the first time, the user now has an aid for displaying the current load - without dangerous measurements on the mains voltage!
An inspection of unknown light sources - e.g. new retrofit lamps - is therefore possible without additional measuring equipment. All you need is the connected UD-700-X2-DALI dimmer, a USB cable (USB type A to Micro B m/m) and our free software.
Application:
- lighting control in museums, churches, event rooms
- dimmer for smart home systems of other manufacturers (e.g. KNX, Loxone, LCN, Wago, Comexio and much more)

Parameterisation with ProgramDesigner
The Universal Dimmer can be conveniently parameterised via USB using the software tool
Here the description of the software
Examples of parameterisation options:

- leading edge or trailing edge control
- setting the dimming curves
- feedback of dimmer status (diagnostic messages)
- emergency operation in case of BUS failure
