Dc load simulates LED for driver testing

November 13, 2009  EP&T Magazine

CHROMA SYSTEMS 63110A LED simulator for driver testing delivers electronic load to allow the forward voltage (Vf) and operating resistance (Rd) to be adjusted to the LED’s V-I curve and simulates ripple current characteristics of typical LED’s. The devices load also has increased bandwidth to allow for PWM dimming testing. Until now, LED drivers have been typically tested with actual LED’s or resistive elements. Product provides faster test methods, automation and repeatable load characteristics.
