The RACT20 ac/dc LED drivers are linearly dimmable without flicker from 100% down to zero. They rely on a special TRIAC input that is unaffected by PFC circuits. The drivers are available with either a 230- or 115-Vac input and a 20W rating to support five to15 power LEDs or LED-chains with constant currents of 350, 500, 700, or 1,050 mA. PFC is greater than 95%, better than EN 61000-3-2 requirements. Tailored for indoor apps, the RACT20 drivers measure 32.6 mm x 16.5 mm x 11.1 mm and are EN/UL 60950-1 certified.
