• Mini RGB DMX Controller PowerLED 3 channel

    Mini DMX Controller RGB Power-LED Driver, 3channels.

    DMX-Circle is a super-miniature, DMX controlled, 3 channel LED driver board for current-driven powerLEDs. 350mA version capable of running upto 6x 1Watt LEDs per string at 28V supply. 500mA and 700mA versions also available. Ideal for OEM integration into small-form factor light fixtures.

    Our Mini DMX Controller, imaginatively called “The DMX Circle” was originally designed to feature ” hot-dock ” connection ports. This allows us to design customer custom light engine fixtures which dock and connect straight onto the dmx mini controller; with no interconnection wiring required.

    Need help selecting the best LED light control system?
    Please don’t hesitate to call us today on: +44 (0) 207 617 7311

    Can I have a custom LED Controller?
    Well…MEGALED also design OEM circuits and the LED Dmx Controllers
    we offer can be designed just for your application as ” mini as practicably feasible”.

    Can I use this dmx controller to dim LED Strip?
    This product is designed to power and dim “constant current” led products
    like downlighters, light panels etc.  To dim led strips like 12V led tape and
    24V flexible led strip or 12V sign lighting modules you may want to search
    above for “constant voltage” or CV for short. Or you can simply give us a call
    and we’ll be happy to help.
