UL/ RAILWAYS Certified Constant Current LIGHTLINE Features LED Driver DC/DC-Converter Wide Input and Output Voltage Range Digital PWM and Analogue Voltage Dimming Regulated with 5 year Warranty Short Circuit Protected Converters Pinned or Wired Versions IP67 rated for /W Version 96% Efficiency 5 year Warranty Constant Description Current LED The RCD series is a step-down constant current source designed for driving high power white LEDs. Standard output currents available are 300mA, 350mA, 500mA, 600mA, 700mA, 1000mA and 1200mA to make this driver compatible with a wide range of LEDs applications. Despite its compact size, the RCD series is fully Driver featured with very high efficiency, wide input voltage range, high ambient operating temperature and two means of dimming: PWM/digital control and analogue voltage dimming. Both dimming controls are independent and can be combined. The driver is also designed to be as reliable as the LEDs it is driving, even at the full operating temperature. Options include an IP67-rated wired version (/W) and a version with built-in reference output vol- tage (/Vref) to power sensors or for easy analogue dimming.
