UT659A UT659D LED Tester
UT659 series products are widely used in LED unmarried lamp bead examine (UT659D), inspection and service of LCD TV backlight, strip mild and modulator tube, and many others UT659A/UT659D LED tester supports full voltage (85V~265V, 50Hz/60Hz) input, which might be used after 1 minute of power-up to ensure steady voltage output When appearing a LED check at 30mA/300V, the LED polarity could be mechanically identified, and the output voltage is adaptively adjusted consistent with the ahead voltage drop of the tested LED
