UNI-T UT659D LED tester ? 24V to 300V

UNI-T UT659D LED tester is widely used in LED single lamp bead test, inspection and repair of LCD TV backlight, strip light and modulator tube, etc. This LED tester supports full voltage (85V~265V, 50Hz/60Hz) input, which can be used after 1 minute of power-up to ensure stable voltage output. When performing a LED test at 30mA/300V, the LED polarity can be automatically identified, and the output voltage is adaptively adjusted according to the forward voltage drop of the tested LED.
