SMD Constant Current LED Driver LIGHTLINE Features Built-in Class A or Class B EMC Filter DC/DC-Converter Wide Input and Output Voltage Range Digital PWM and Analogue Voltage Dimming Regulated with 5 year Warranty Short Circuit and Overtemperature Protected Converters Low Cost EN/RAILWAYS Certified 5 Year Warranty Description Constant 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 Current LED 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 Driver 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.

All LED Drivers may not be used without a load. They must be switched on the primary side only. Noncompliance may damage the LED or reduce its lifetime. 2. It is not possible to parallel the drivers to increase the current.
