Velleman K8064: DC Controlled Dimmer Kit

Velleman K8064

DIY DC Controlled Dimmer Kit

Adjust the brightness of one or more lamps by direct current voltage using the Velleman K8064: DC Controlled Dimmer Kit. Employ your dimmer to work with stage lighting, domotics, and other like projects. The "soft start" feature ensures the K8064 doesn't put any additional wear on your lamps while transformer protection will shield it from any faulty light sources. The K8064 adheres to EN55015 guidelines on suppression of TV/radio signal interference.

You can use this dimmer with either a resistive load or inductive load. For low-voltage halogen lighting, use a conventional wirewound transformer. Note that most electronic transformers are not compatible with the K8064. Adjust brightness through an adjustable direct tension, with which you can use several sources such as our computer interface boards: K8055, K8055N or VM110N.


  • Simple brightness adjustment by means of a DC voltage
  • Optically isolated adjustment input
