New 20Watt AC/DC-LED-Driver with PFC Is Dimmable Down to Zero and Flicker-Free

TRIAC-dimmers were originally designed to dim incandescent filament lamps. Already the use of CFL lamps causes many problems and the story is continued with LED lamps. 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.
