DC electronic load IT8912E

programmableRS-232with USB interface

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. IT8900 series provides CR-LED / CC / CV + CC / CR /CW and other working modes, built-in USB / RS232 communication interface. Widely used in LED driver power dimming test. Feature ♦ Up to 20KHz CC dynamic mode ♦ Voltage / current measurement speed up to 50KHz ♦ Various working modes for choice. CR-LED/CC/CV+CC/CR/CW etc. ♦ Unique CR-LED mode, providing the perfect PWM-LED Driver test solution ♦ Easy programmable parameter setting,applicable for simulating LED lights with different characteristics ♦ Automatically determine whether the test results beyond the set specifications according to high / low limit specifications of the test parameters ♦ Adjustable frequency,duty ratio PWM dimming output port ♦ I-pp/I-max measurement function can test current ripple and start up surge current of LED constant flow source ♦ Built-in USB/RS232 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.
