The IT8912E LED Load Simulator is designed to emulate real-world conditions for testing LED drivers, providing high-speed and high-precision simulation for PWM dimming and constant current sources. Its CR-LED mode is a standout feature, designed specifically for testing LED drivers without the instability often seen in traditional methods. This mode offers better frequency bandwidth and minimizes voltage and current jitter, enhancing the reliability and accuracy of LED driver testing. The I-pp/I-max measurement feature ensures thorough testing of LED constant flow sources, measuring current ripple and start-up surge, which are critical for evaluating the performance and longevity of LED drivers.

The IT8912E series simplifies LED driver testing by offering easy programmable settings for simulating various LED light characteristics, and supports both automatic test functions and limit checks, making it highly efficient for use in both R&D and production line testing.
