Universal Dimmer UD-700-X2

The reliable Universal Dimmer has been developed to dim all via leading edge/trailing edge dimmable light sources (e.g. LED lamps). 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.

Quick Facts

  • 2 channels 700W each or 1 channel 1400W
  • flicker-free dimming of LED lamps
  • automatic load detection
  • oscilloscope function
  • DMX, ISYGLT
  • 1-10V / 0-10V
  • single-button dimmer

The Universal Dimmer is suitable for the reliable operation of high-voltage lamps, magnetic transformers, electronic transformers, ESL and LED retrofit lamps. Two separate dimmer outputs are 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 types of the dimmer:

  • ISYGLT BUS protocol
  • DMX512 8Bit and 16Bit
  • stand-alone: 0-10V, 1-10V, push-button (single-button dimmer)
  • internal potentiometers
  • to the BUS protocols ISYGLT or DMX512, the internal potentiometers and voltage inputs can be parameterised as priority, merge operation or for the BUS failure

 

For ISYGLT users, the functions can be parameterised as usual in the ProgramDesigner. A free software tool is available for standalone and DMX 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 dimmer, a USB cable (USB type A to Micro B m/m) and our free software.

Parameterisation with ProgramDesigner

For the first time, this dimmer offers separate parameterisation options for ISYGLT and DMX512 / stand-alone.

For DMX512 and stand-alone you will find the description of the possibilities here. In the ISYGLT ProgramDesigner you will find the parameterisation options for the ISYGLT operation:

  • parallel connection of the outputs from 2x 700W/VA to 1x 1400W/VA
  • leading edge or trailing edge control
  • setting the dimming curves
  • feedback of the dimmer status (diagnostic messages)
  • emergency operation in case of BUS failure
