UT659 Series LED testers

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.
