LDJB-1200 microcomputer relay protection tester

The whole process and the result of the test will all be showed on the LCD. The Chinese operational interface of the complete set is very friendly and convenient. The tracking ball and keyboard on the faceplate will implement the operation. The operation is simple and convenient, and is easy to be mastered. Operator only needs a little knowledge of computer. 
 

Keyboard and mouse interface are also located on the faceplate. If you would like to use the external mouse and keyboard, through pluging them with corresponding interfaces, you can operate this tester just like operating a desk-top computer.

High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced. Since integrative structure is adopted,the structure of the tester is layed compactly.The distance of data transmission is short with tight structure, which overcomes the problem of fewer points of waveform output due to long data communicational line and narrow frequency band when using the test controller controlled directly by PC.
