• 3 channel DMX Controller PowerLEDs

    DMX Circle – RGB PowerLED 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.

    DMX Circle also features ” hot-dock ” connection ports allows us to design customer OEM light engine fixtures which dock and connect straight onto the controller, with no wiring required.
