Main Features

1.Meet all test requirements on site.The instrument has standard four phase voltage and three-phase current output. It can test not only various traditional relays and protection devices, but also various modern microcomputer protections, especially for transformer differential protection and standby automatic switching device. The test is more convenient and perfect.
2.All kinds of technical indexes fully meet the standard of DL / t624-1997 "technical conditions for microcomputer based test device of relay protection" issued by the Ministry of electric power.
3.Classic Windows XP operation interface, friendly man-machine interface, easy and fast operation; high performance embedded industrial control computer and 8.4 inch resolution 800 × 600 TFT true color display screen, can provide rich and intuitive information, including the current working state of the equipment and various help information.
4.This Windows XP system has its own recovery function to avoid system crash caused by illegal shutdown or misoperation.
5.Equipped with ultra-thin industrial keyboard and photoelectric mouse, it can Complete all kinds of operations through keyboard or mouse just like ordinary PC.
6.The main control board adopts DSP + FPGA structure and 16 bit DAC output. It can generate 2000 high density sine wave per week for fundamental wave, which greatly improves the quality of waveform and the accuracy of the tester.
7.The high fidelity linear power amplifier ensures the accuracy of small current and the stability of large current.
8.USB interface is used to communicate with PC directly without any connecting line, so it is convenient to use.
9. Can be connected to laptop (optional) to run.Laptops and industrial computers use the same set of software, so there is no need to relearn the operation method.
10.Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1A), 220V (0.6A).It can be used for relays or protection devices that need DC power supply.
11.It has the function of software self calibration, which avoids opening the case to calibrate the accuracy by adjusting the potentiometer, thus greatly improving the stability of accuracy.
