Product description


■ Expandable hardware architecture, convenient for customers to add or remove various test equipment according to their needs

■ The system supports multiple communication interfaces (GPIB,USB, RS-232, LAN, etc.)

■ Independent eight-channel hardware architecture, no need to switch, high test efficiency, eight-channel simultaneous test or four-channel group test can be performed, and it can be expanded to more channels according to actual needs

■ The system opens the test project editing function, and users can create, delete, add, modify, and store test databases for different products

■ Online instrument debugging function

■ Operator multi-level authority setting and management

■ Provide system logs to facilitate fault location and operator related information query

■ Each channel supports independent barcode or QR code reading function

■ It can be connected with supporting tooling and fixtures to realize offline or automated production line testing

■ All functional units can be installed and disassembled integrally or modularly

■ The system reserves the I/O interface, and it can be connected to the automated production line without additional hardware

■ Real-time storage of test data and output real-time display function, which can analyze quality and capacity


Application field

* Testing of chargers for consumer electronics such as mobile phones, PADs, electric toothbrushes, electric shavers, electric hair clippers, wireless earphones, etc.

* Test of adapter power supply for laptops, routers, switches, etc.

* Power test for imaging products such as printers, copiers and fax machines

* Industrial power supply and other module power supply (AC/DC, DC/DC) testing


System introduction

■ TH300 power supply test system is an efficient, flexible, and expandable automatic test system for various power supplies.It provides numerous hardware options, such as programmable AC/DC power supplies, electronic loads, oscilloscopes, data collectors (or multimeters), power meter, etc. Combined with an open hardware architecture, it can meet various testing needs of users.

■ TH300 supports communication methods such as USB, LAN, GPIB and RS-232. According to the special needs of users, the corresponding instruments can be integrated into the system.

■ TH300 test software contains a series of standard test items for power supply. At the same time, users can add new items independently according to test requirements.

■ TH300 provides real-time graphical data display functions, such as hourly output, hourly pass rate, daily pass rate, and pass rate of each channel.

Software introduction 

Flexible scalability

TH300 supports communication methods such as USB, LAN, GPIB and RS-232. It is compatible with test equipment with above interfaces. 


Humanized test interface

The test interface is simple and generous and the layout of each functional area is reasonable. Also, the operation is convenient and the relevant data is displayed in graphs.


Test interface


Multi-level authority management

TH300 can set different user rights according to actual production needs, such as database editing,online debugging of instruments and meters, user addition and reduction rights.


Rich database functions


Users can create a product test database (new or copy) according to their own test requirements, edit different test items, and make any adjustments in the test process. You can also insert or delete different test items in the test process, greatly improve the flexibility of data editing.
