RCD-24-0.60/SMD/OF

● ● ● ● ● ● ● ● Features Regulated Converters UL Certified Constant Current LED Driver Wide Input and Output Voltage Range Digital PWM and Analogue Voltage Dimming Short Circuit and Overtemperature Protected Pin, Wire or Open Frame SMD Versions IP67 rated for /W Version 96% Efficiency 5 year Warranty LIGHTLINE DC/DC-Converter with 5 year Warranty Constant Current LED Driver Description 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 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), an open frame version with SMD pins (/SMD/OF) and a version with built-in reference output voltage (/Vref) to power sensors or for easy analogue dimming.
