LED: Constant Voltage Dimming
Posted by Wayne Howell on 08 June 2013 09:36 AM

There are two key methods of dimming LED: Constant current (CC) and constant voltage (CV). CV dimmers put out a constant voltage and the current control is done by the LED fixture. This type of dimming tends to be used for the lower power LED products such as Flexi-Strip. CC dimmers put out a controlled current, which means that the fixture does not need electronics for current control of the LED. This style of dimming is used for higher power LED products such as Rebel.

It is import ant to choose the correct technology of dimmer as an incorrect choice will most likely damage the fixture.

Below is a summary of the Constant Voltage dimmers offered by Artistic Licence:

Rail-Pipe HC Is a high current DMX dimmer for 2 x RGB circuits (6 channel).

  • Voltage: 12-24V. 
  • Current Max: 20A per product, 10A per RGB circuit
  • Control: DMX512 / RDM
  • Form: Din Rail


Art-Pipe is a 8 x RGB circuits (24 channel) dimmer with network control.

  • Voltage: 12-24V. 
  • Current Max: 10A per product, 2A per RGB circuit. (Note that RGB circuit current is limited by maximum, so if all channels are equally loaded, the limit per RGB circuit is 1.25A 
  • Control: Art-Net
  • Form: Din Rail

Flexed-Up is a standalone dimmer / controller for RGB with numerous internal programmes.

  • Voltage: 12V. 
  • Current Max: 12A per product, 2A per RGB circuit
  • Control: Contact closure.
  • Form: Din Rail
