The RCD series of constant current LED Drivers from Recom has been extended to a maximum of 1200mA to provide the higher currents needed by the next generation of high brightness LEDs. The RCD-24-1.0 and RCD-24-1.2 DC/DC converters deliver a stable maximum current of 1A or 1.2A respectively from a wide input voltage range of between 5V and 36VDC. The modules measure only 22mm x 12.5 x 8.5mm and yet are fully complete plug-n-play units requiring no external components, thus reducing the circuit footprint compared with alternative discrete solutions by up to 50%.
The RCD series have two independent dimming inputs: a PWM control that allows simple interfacing with microprocessors and digital controllers and an analogue voltage input that is suitable for lighting controllers or rheostat dimmers. Both dimming inputs are linear and the dimming range covers 0%-100%. The PWM input can also be used to shut down the converter to draw only 200µA from the supply.
The sophisticated feedback control circuit used in the RCD family of LED drivers ensures excellent load and current regulation, resulting in LED current stability of ±1%, a residual output ripple of less than 200mV and efficiencies of up to 96%. The low internal power dissipation of only 800mW permits the ambient operating temperature range of -40°C to +71°C for the 1000mA version and -40°C to +65°C for the 1200mA version. The drivers also feature short circuit protection and thermal shutdown.
The drivers have been designed to be as reliable as the LEDs they are driving and contain no electrolytic or tantalum capacitors.
About RECOM Electronic GmbH
Incorporated in 1975 RECOM Electronic GmbH originally was a supplier for high precision metal- film- resistors and- networks, becoming a pioneer for miniature DC/DC-converters in the mid 1980`s. Today RECOM is a leading supplier of converters in the power range from 0.25 Watt to 60 Watt and above.
Our core focus- development & design, production and marketing span three continents - America, Europe and Asia, thereby ensuring close proximity to our customer base worldwide.
Leading international corporations have selected RECOM as their strategic supplier for power supplies. The continued expansion of our international presence makes RECOM an important partner for the global industrial automation industry, aerospace, medical, transport and communication.
The RECOM group of companies is committed to continue to be at the forefront of technological developments.
