UT659 series products are widely used in LED single lamp bead test (UT659D), inspection and repair of LCD TV backlight, strip light and modulator tube, etc. UT659A/UT659D 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.
