1w/3w high-power led driver

Velleman K8071: 1W/3W Power LED Driver

Velleman K8071

Velleman K8071 High-power LED Driver Kit

The K8071 driver board may be compact in size, but it delivers a constant current that can support high-power LEDs. The driver can support either two 3W LEDs or up to four 1W LEDs. Simply hook the K8071 up and admire the light that it generates.

With short circuit-protection and a switch mode priniciple, the K8071 operates with the highest efficiency. A heatsink is not required with this driver and a rectifier to connect to an alternating current source is built in so all you really need is the LEDs. This board does require basic assembly and soldering.

Use the K8071 to light up your home, workspace, science or art projects, stages, and any other space that could stand a bit of brightening. Or, employ the fixed current of the driver for a NiDc/NiMH battery charger circuit.

Also available as a completely mounted module, The Velleman VM143/1W for 1W LEDs, or the Velleman VM143/3W, for 3W LEDs.
