Overview

IT8900 series high accuracy LED specific testing electronic loads can simulate the real output of LED lights with different characteristics. Their specific circuit can realize CR-LED mode,adjustable frequency, duty ratio PWM dimming output port(frequency:20HZ-2KHZ),I-pp/I-max measurement function can test current ripple and start up surge current of LED constant flow source. Voltage and current testing speed can reach 50KHZ.Widely used in LED driver power dimming test.
CR-LED mode.

The unique CR-LED mode developed by IT8900 series is especially applicable for LED driver test. The user only needs to set the operating voltage, current and coefficient of LED driver to obtain real output parameter of LED driver. Different from universal electronic load, this mode of IT8900 series adopts pure hardware circuit design without software operation by MCU module, thus increasing the speed and stability of CR mode control circuit, solving voltage and current jitter during LED driver test, increasing frequency width and helping realize PWM dimming.
