0 330VKT4H Smart Fit Manual Adjusting Voltage TV LED Backlight Tester Current Adjustable Constant Current Board LED BuFeatures 1 Manual stepless pre conditioned open circuit voltage 20 330VDC When testing intelligent fully adaptable to the LED voltage light source and no need to adjust 2 When the output voltage is pre set to 20V or lower use 1mA of the transfer current to check if the IC is turned off various IC supply voltage parameters to see if the IC is good or wrong when testing a single lamp it never burns the lamp 3 The maximum short circuit current limit 20 150 mA can be adjusted manually and the current is fully automatic 4 Regardless of whether the high voltage or low voltage the lamp can be ultra bright safely 5 Specially when adding 1 mA of accurate wide voltage 0 330 V DC it can develop various brilliant applications For example diode voltage regulator Triode MOS tube and other positive and reverse voltages And the capacitance is lower than 330V a sensitive voltage resistor a TV diode and other voltages or voltages 6 Test the constant current board if the TV has only one group of lamps you can directly check the board s good or bad constant current to make sure the problem is backlight or the current board is constant Specification Product Model TD3HVB 85 265 VACVOut 0 330 V DC automatic adjustable Accuracy Voltmeter ± 0 5 ± 1 VO capacitance ut V shaped notchЯOut 0 150mA automatic adjustable DC current test board current 0 999mAAccuracy accuracy ± 2 ± 1 IOut MAInput signal 50VA max Temperature 20 40 ℃Product Information
