Product Overview

The LFGF solar photovoltaic junction box tester is a specialized testing instrument developed for electrical characteristic testing of photovoltaic junction boxes and other supporting components. It can test parameters such as voltage drop, leakage current, temperature drift, and DC resistance of junction boxes and their components, and can meet the testing requirements of 20-500W junction boxes (10 diodes to one diode). It can be widely used in junction box manufacturers and photovoltaic module manufacturers to test the electrical performance parameters of junction boxes, in order to improve the performance and quality of junction box products.

The LFGF solar photovoltaic junction box tester is controlled by a microcomputer and features a large 320 * 240 dot matrix LCD screen for fast measurement and clear display. And it has the function of fault alarm. During measurement, there is no need for users to repeatedly plug and unplug the wiring terminals and reverse the wires. According to the human-machine dialogue, all electrical performance parameters of the photovoltaic junction box can be automatically, quickly, and accurately detected in one go, improving users' work efficiency.

Features

The volt ampere characteristic of a diode, which refers to the voltage drop during conduction;

● Reverse leakage current of diode;

The current temperature rise test is to repeatedly detect the conduction voltage drop and reverse leakage current of diodes at room temperature and high temperature through a certain working current and a certain period of time; Note: This function is only used for auxiliary testing purposes.

Conduct DC resistance test, which can determine whether the leads of the junction box are short and whether the riveting is reliable by testing the resistance value of the wires;

● Leakage current and conduction voltage drop thresholds (limit values) can be set,

If the diode is reversed or damaged, there will be a buzzing alarm, a light alarm, and a Chinese prompt.
