RCD-24-0.35

Features Regulated Converters Rev.1 Description ● ● ● ● ● ● Constant Current Output Power LED Driver Wide Input Voltage Range PWM/Digital Dimming and Analogue Voltage Dimming Short Circuit Protected 96% Efficiency INNOLINE DC/DC-Converter RCD-24 Series Constant Current Single Output 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 and 700mA to make this driver compatible with a wide range of LEDs from many different manufacturers without the need for any external components. 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 LED 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 of 85°C.
