The Universal Dimmer is suitable for the reliable operation of high-voltage illuminants, magnetic transformers, electronic transformers, ESL and LED retrofit illuminants. There are 2 separate dimmer outputs available, each of which can be loaded with 700W. By configuring and switching the outputs in parallel, the dimmer can be loaded with 1x 1400W.
Each channel can be parameterised separately for the corresponding load type (leading edge or trailing edge mode). The dimmer automatically checks the connected load by carrying out a short test after applying the operating voltage for the first time to see whether the connected load can be operated with the desired setting.
The dimmer operates with an internal dimming resolution of 16 bit and thus meets the highest demands.
The properties already predefined at the factory, such as dimming curves, minimum and maximum limits, can still be changed and optimised by the user himself.
Control modes of the dimmer:
- DMX512 8 bit and 16 bit
- DMX-RDM 8 bit and 16 bit
- Stand-alone: 0-10V, 1-10V, button (single-button dimmer)
- internal potentiometers
- For the DMX512 BUS protocol, the internal potentiometers and voltage inputs can be parameterised as priority, merge operation or for BUS failure.
A free software tool is available for stand-alone or DMX users. With this tool, the dimmer can be optimised by parameters via USB or RS-485 data connection and internal data such as temperatures, voltages, peak currents and power can be displayed. In addition, an oscilloscope function is integrated as a novelty. This means that, for the first time, the user also has a tool for displaying the current load - and without dangerous measurements on the mains voltage!
A check of unknown illuminants - such as new retrofit lamps - is thus possible without further measuring equipment. All you need is the connected UD-700-X2-RDM dimmer, a USB cable (USB type A to Micro B m/m) and our free software.

Setting options for the DIP switches
| Function | Operating mode |
|---|---|
| U input 1-10V | Control via digital potentiometer from switch manufacturer, or 1-10V dimmer coupler (behaves like an ECG from fluorescent lamps - the 10V for the 1-10V dimming is supplied by the dimmer) |
| U input 0-10V | Control via external control e.g. PLC with 0-10V (0-10V voltage is supplied from the PLC) |
| A/B/C/D | See table below |
| Reserve | Not assigned in this operating mode |
| Channel 1+2 coupled | The dimmer works 1-channel, power 1x1400W; bridge between outputs LD1 and LD2 required |
| Channel 1+2 separat | The dimmer works 2-channel, power 2x700W; the LD1 and LD2 outputs must not be connected together |
| Single-button dimmer | Control via standard keys on terminals UE1 and UE2 against GND press briefly = On/Off, press longer = dim |
| Analog 0(1)-10V | Analog control - in this position the DIP switches 3 are enabled for the selection 0-10V or 1-10V |
