LED TV Backlight Tester 18W 0-300V

Adaptive voltage, current, automatic identification of lamp beads and light strips. Adaptive voltage 0-300V, suitable for most series-parallel lamp beads test. When testing, use soft starts, the voltage automatically adjusts, the current gradually increases, never burn the lamp beads, three to five seconds to reach the normal brightness. High brightness, no need to remove the screen to illuminate the LCD TV screen. Use high-speed microcontroller to perform voltage sampling test and drive LED lights to display voltage, so as to realize board integration and reduce the wrong rate. With the light bars and light beads, the positive and negative reverse connection function will not burn the light bar and light beads. Insulation from hot, cold and earth, never electrocution. Built-in power cord and housing design, easy to realize. Digital display, real time voltage output, with adjustable voltage inside, voltage value can be self-corrected. Digital meter using green light emitting tube, the display for 00 should indicate a short circuit, the 300V display is open circuit. Each group of LED strips on the same LCD TV must display the same voltage.
