LED Tape Dimmer Module

Fineline Solutions has been working with LED lighting for many years, and projects often require large lengths of LED tape to be incorporated into set pieces and stages. Initially, we used widely-available DMX LED drivers for our projects, but quickly found that they simply aren’t designed for heavy use. Connectors became unreliable, and short-circuits caused by pinched cables within the set caused dimmer modules to catch fire. Clearly this isn’t the kind of problem you want to be dealing with on tour!

In response to the poor quality of the available dimmer options, Fineline Solutions decided to design their own robust dimmer module, incorporating many features to ensure that the dimmer works when you need it to:

  • Reverse polarity protection on supply terminals
  • Soft current limiting and short-circuit protection for each channel
  • Resettable supply fuse for each XLR
  • Robust, panel-mounted XLR connectors for connection to LED tape

The module is available as a single, populated PCB complete with XLR connectors. It has been designed to be panel-mounted: it is possible to fit two modules side-by-side in a 1RU panel. The module incorporates front-panel status LEDs for power, DMX reception, test mode and faults. DMX addresses can be set via a standard DIP switch on the rear of the module, or alternatively via DIP switches mounted on a remote panel. RDM firmware is planned to allow the start address to be set remotely.
