Most E-Load manufacturers have similar designs but are unable to simulate the I-V curve of the LED as well as internal capacitances causing abnormal OCP, OVP. Therefore, other E-Loads are not suitable for testing LED drivers.
The 63110A was specifically designed to simulate LED characteristics to test the functions of LED drivers. Not only can it test in stable conditions, it can also test turn on, PWM dimming characteristics of the LED driver and the Rd value can be adjusted according to the LED V-I curve making it an irreplaceable load choice for LED driver testing.
