Introduction to DBC-041 thyristor comprehensive characteristic tester

Thyristor comprehensive testerModel:XFR-DBC-041

The volt ampere characteristics and triggering characteristics of thyristors are the most fundamental characteristics of thyristors, and the quality of these characteristics directly affects the normal use of the device on the whole machine. Therefore, detecting the volt ampere characteristics and triggering characteristics of thyristors is crucial in the production, distribution, and use of thyristor devices. Testing the above parameters is usually done by a thyristor volt ampere characteristic tester and a thyristor gate trigger characteristic tester. When testing the volt ampere characteristic parameters, an additional oscilloscope is required to observe the volt ampere characteristic curve. The conventional price of the above three instruments is over 7000-10000 yuan, and they have a large number of units, occupy a large area, and are inconvenient to operate. We have developed a comprehensive tester for thyristor volt ampere characteristics and trigger characteristics that combines the above three instruments according to the needs of our customers, which has been highly praised by our customers.

The testing method of this tester complies with the national standard GB4024-83, and is controlled by a microcontroller for automatic testing and digital display. The circuit design is simple and concise, and the built-in oscilloscope can directly observe the volt ampere characteristic curve. It has the characteristics of small size, light weight, simple operation, accurate testing, reliable protection, convenient maintenance, and low price. It can test the forward and reverse non repetitive peak voltage, reverse repetitive peak voltage, forward and reverse repetitive peak leakage current, and gate trigger current and trigger voltage of various thyristors and thyristor modules. It is a comprehensive testing equipment for thyristor device manufacturers, device distributors, and machine manufacturers to test multiple parameters of thyristors.

During the use of thyristors, their volt ampere characteristics and triggering characteristics will gradually deteriorate due to various factors such as overcurrent, overvoltage, and overheating, and may even fail to maintain normal use or be damaged. Therefore, when carrying out overall maintenance, it is beneficial to test and confirm the performance of used components and components that need to be newly installed before installing them, which is beneficial for eliminating equipment failures and avoiding detours.
