The RBD-12 series is a Buck-Boost constant current source designed for driving high power LED applications.
Two output currents are available, 350mA and 500mA, and the maximum output voltage is 40V. The drivers
have digital and analogue voltage dimming control and a regulated reference 5V output. Typical applications are
solar, off-grid lighting, mobile traffic signs and battery-powered lighting. The wired version is IP67 rated.
