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.
