RCD-48-1.20/M

Features LED DRIVER ● ● ● ● ● ● ● 70W Buck LED Driver Constant Current Output (350 to 1200mA) Digital PWM and Analogue Voltage Dimming High Efficiency to 96% EN, UL and RAILWAYS Certified Metal or Plastic Case Version IP67 Rated for /W, Plastic Case Version LIGHTLINE DC/DC-Converter with 5 year Warranty Description The RCD-48 series is a step-down constant current source designed for driving high power LED applications. Four output currents are available. The maximum output voltage is 56V. The buck drivers have digital PWM and/or analogue voltage dimming control and are special featured with very high efficiency. Typical applications are 48V bus lighting solutions or high voltage LED arrays (e.g. high bay lights).
