Date Announced: 21 Nov 2011 The LED Lighting industry is blossoming, especially as LED strings become longer and multi-chip arrays larger. With larger arrays and strings, the required input voltage for buck-drivers has increased along with the amount of constant current that needs to be supplied. The problem is that most currently available models have a limit of approximately 40V. Not any longer with the introduction of RECOM Powers NEW RCD-48 Series. The RCD-48 series is a step-down constant current source designed for driving high power LED applications. With input voltage up to 60VDC and constant current outputs of 350, 500, 700 and 1200mA the RCD-48 Series provides power up to 70W. A fixture using the full wattage could possible replace a conventional light that could have used up to 350W! The new buck-driver is ideal for operation with the new longer LED-chains and larger multi-chip arrays – a real technical achievement!The RCD-48-drivers are dimmable down to zero with external digital (PWM) or analogue control. The PWM control input can be directly connected to a microcontroller. Efficiency is rated at 96%, with an operating temperature range -40°C and +85°C. The modules are available with pins for PCB mounting or with flying leads for non pcb applications. While the powerful 1200mA version features a metal case, the smaller models are designed in plastic cases. All types are certified to EN/UL-60950-1. The MTBF is specified at MIL-HDBK217F with 1.7 million hours. The warranty is 5 years. Samples are now available by leading distributors from stock.
