Description
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.
● 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

All LED Drivers may not be used without a load.
They must be switched on the primary side only.
Noncompliance may damage the LED or reduce
its lifetime.
Note 1: Output Current Accuracy is defined as:
[(Iout - Iout “rated“) / Iout “rated“] x 100
Note 2: Output Current Stability is defined as:
[(Iout “deviation“ - Iout “nominal“) / Iout “nomi-
nal“] x 100 Iout (deviation) = maximum Deviation
(min. Load, max. Load)
