UT659A UT659D LED tester
UT659 collection products are widely used in LED single lamp bead examine (UT659D), inspection and repair of LCD TV backlight, strip gentle and modulator tube, and many others UT659A/UT659D LED tester helps complete voltage (85V~265V, 50Hz/60Hz) input, that are used after 1 minute of power-up to guarantee steady voltage output When appearing a LED examine at 30mA/300V, the LED polarity would be robotically identified, and the output voltage is adaptively adjusted in line with the ahead voltage drop of the examined LED
