LED Lamp Bead TV Backlight for All LED Lights Repair Output 0~300V

Features:High speed single- microcomputer is d for voltage sampling test, and LED lamp is driven to display voltage (by no means other products on the market purchased heads, which are installed separately) to achieve board card integration and reduce defective rate (beca the current is constant, only the voltage display function is d.)0-300V adaptive voltage, suitable for most series and parallel lamp bead tests. During the test, the gradual startup mode is adopted, the voltage is automatically adapted, the current is gradually increased, and the lamp beads will not , and the normal brightne can be achieved in three to five seconds. The positive and negative poles of the lamp bar and lamp bead are connected inly, without ing the lamp bar and lamp bead.Dial display of real-time voltage output, with adjustable voltage, the voltage value can be s calibrated. The dial meter adopts green light-emitting tube. 00 indicates short circuit and 300V indicates open circuit. The display voltage of each group of LED light bars of the same LCD TV shall be the same.Cold and hot isolation, never get . The integrated design of the power cord and the machine box es it easy to carry when going out.You can light up the LCD TV screen without removing the screen. (The screen with bad lamp beads will light up as well. The LCD TV is generally divided into severaroups in parallel. The voltage can be d to see which groups have different voltages, so as to determine which groups of LED lamp beads are damaged.)Specifications:Item: LED Lamp Bead TV Backlight Material: ABSInput Voltage: 85-265VOutput Voltage: 0-300VPower: 18WSize: 10.4*3.6*6.3cmPackage Size: 18*10.5*4cmPackage Weight: 255gNote:When the positive and negative poles are uncertain, please 19V voltage to detect the positive and negative poles. It is prohibited to 300V voltage to detect the positive and negative poles. 300V voltage may ca damage to the equment. Short circuit the pen for three seconds to switch between high and low voltages.Package List:1* LED Lamp Bead TV Backlight 1 *Pair Test Probe
