Recom: New 20Watt AC/DC-LED-Driver with PFC is dimmable down to zero and flicker-free

LED lamps are the future to illuminate our houses and also public/commercial rooms. Therefore reliable solutions are a must to get the acceptance for these innovative light sources. The elimination of traditional lamp types increases the need for alternative dimming methods.

The use of TRIAC-dimmers in LED-systems causes unwanted flicker, visible to the eye, due to phase modulation. This prevents linear dimming of LEDs down to zero. If existing TRIAC-Dimmers are to be used with LED-systems, a new type of LED-Driver is required.

RECOM releases the RACT20-family, a new generation of AC/DC-drivers, that can be dimmed linearly and without flicker from 100% down to zero. The RACT20-family is equipped with a specially developed TRIAC input, which is not affected by the PFC-circuit of the driver. An ideal solution for many LED-systems, where dimming is easy.

These new AC/DC-drivers are available with either 230VAC or 115VAC input. They offer 20 Watt and can support 5 to15 power LEDs or LED-chains, with constant currents of 350, 500, 700 or 1050mA. The power factor (PFC) is >95% and therefore better than required by EN 61000-3-2 and meet the class C requirement.

RACT20-drivers are designed for indoor applications, class IP20 and measure only 32.6 x 16.5 x 11.1mm (L x W x H). They are EN/UL 60950-1 certified with a “Design Lifetime” >70.000 hours. Warranty is 5 years.

Samples are now available by Arrow from stock. More details are available on www.recom-electronic.com or can be requested via email to lighting@recom-electronic.com.
