Description
The RCD-24-xxx/PL series is a step-down constant current source designed for driving high power LEDs.
The converter uses a pinless SMD open frame design to reduce cost and size. Output currents available are
300mA, 350mA, 500mA, 600mA, 700mA and 1000mA with either Class A (Suffix /A) or Class B (suffix /B)
built-in EMC filtering. Despite its compact size, the RCD-PL 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 ambient operating
temperature and is designed for strip lighting, wall washers and flourescent tube replacement designs, where
a low profile and narrow width are demanded.
