Chroma Systems Solutions released an LED simulator for driver testing. The 63110A electronic load allows 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 63110A load also has the bandwidth to allow for PWM dimming testing. It can also test turn on and PWM dimming characteristics of the LED driver, and the Rd value can be adjusted according to the LED V-I curve.
