Features LED DRIVER ● ● ● ● ● ● ● ● Buck- Boost LED Driver up to Vout=40V Constant Current Output (350 or 500mA) Digital PWM and Analogue Voltage Dimming High Efficiency to 92% EN60950-1 and UL60950-1 Certified EMC Class A Without Extern Components Pinned or Wired Version 5 Year Warranty LIGHTLINE DC/DC-Converter with 5 year Warranty Description Constant Current Buck-Boost LED Driver 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.
