Universal Dimmer UD-700-X2-RDM

The reliable Universal Dimmer has been developed to perfectly dim all (via leading edge / trailing edge) dimmable illuminants (e.g. LED lamps). It does not require a minimum load and dims even from one LED retrofit lamp without flickering. Even a large number of LEDs is no problem for the dimmer.

Quick Facts

  • 2 channels 700W each or 1 channel 1400W
  • flicker-free dimming of LED lamps
  • automatic load detection
  • suppression of ripple control signals and mains interference
  • oscilloscope function
  • DMX512 8 bit and 16 bit, DMX-RDM
  • 1-10V / 0-10V
  • single-button dimmer

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.
