Features of Microcomputer Protective Relay Tester

1.4 phase voltage and 3 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.Classic Windows system 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.

3.Self-recovery function to avoid system crash caused by illegal shutdown or mis-operation.

4.Equipped with ultra-thin industrial keyboard and photoelectric mouse, it can complete all kinds of operations through keyboard or mouse just like PC.

5.The main control board adopts DSP + FPGA structure and 16 bit DAC output. It can generate 2000 high density sine wave per cycle for fundamental wave, which greatly improves the quality of waveform and the accuracy of the tester.

6.The high-fidelity linear power amplifier ensures the accuracy of small current and the stability of large current.

7.USB interface is used to communicate with PC directly without any connecting line.

8.It has the function of GPS synchronization test. The device can be built-in GPS synchronous card (optional) and connected with PC through RS232 port to realize synchronous test of two testers in different places.

9.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.

10.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.
