Enhance your LED testing and troubleshooting efficiency with this advanced LED Tester featuring adaptive voltage and current detection technology. Designed with a high-speed microcontroller, this device accurately samples voltage and drives LED lights to display real-time voltage output, providing precise diagnostics for LED strips and lamp beads up to 300V. Its integrated digital display with green LED indicators delivers clear voltage readings and fault codes, making it an essential tool for LCD TV screen repairs and LED lighting projects. Key Features: · High-Speed Microcontroller Control: Ensures accurate voltage sampling and stable LED display, improving board integration and reducing product failure rates caused by constant current issues. · Real-Time Digital Voltage Display: Equipped with an adjustable internal voltage calibration, allowing self-correction and precise measurement during testing. · Clear LED Digital Meter: Green light-emitting tubes indicate voltage status – “00” signals a short circuit while “300V” indicates an open circuit, assisting in quick fault detection. · Adaptive Voltage and Current Identification: Automatically recognizes lamp beads and LED strips, with an adaptive voltage range from 0 to 300V to suit most series-parallel LED configurations. Gradual progressive start prevents damage by slowly increasing current to reach normal brightness within 3-5 seconds. · Reverse Polarity Protection: Safeguards light bars and lamp beads against damage from incorrect positive and negative connections. · Safety Isolation Design: Features hot, cold, and ground isolation to prevent electric shock, with a fully integrated power cord and compact enclosure for easy portability. · High Brightness Illumination: Capable of lighting LCD TV screens without removing the screen, allowing identification of faulty LED groups by comparing voltage levels across segments. · Wide Input Voltage Compatibility: Works with 85-265VAC power sources, making it suitable for various power environments.
