0-300v 18w Led Lamp Bead Light Strip Tester Digital Display Real-time Voltage Output Tv Backlight White EU Plug

Description

Use high-speed single-chip microcomputer to do voltage sampling test. And drive LED lights to display voltage to realize the integration of boards and cards and reduce the defect rate (because the current is constant, only the voltage is used) display function). 0-300V adaptive voltage, suitable for testing most series and parallel lamp beads. The digital display shows real-time voltage output, with adjustable voltage inside, and the voltage value can be corrected by itself.
