Products Features:
1. Meet all test requirements on site. The microcomputer relay protection tester has a standard six-phase
current, six-phase voltage output at the same time, current 30A / phase, voltage 125V / phase. Six-phase
current can reach 180A in parallel. It can test all kinds of traditional relays and protection devices, as well as
all kinds of modern microcomputer protection, especially for transformer differential protection and automatic
switching devices. The test is more convenient and perfect.
2. Various technical indicators have reached the standard of DL / T624-1997 "Technical Conditions for
Microcomputer-based Test Equipment for Relay Protection" issued by the Ministry of Electric Power.
3. Classic WindowsXP operation interface, friendly man-machine interface, easy and fast operation;
high-performance embedded industrial control computer and 8.4-inch TFT true color display with
800 × 600 resolution, can provide rich and intuitive information, including equipment Current
working status and various help information.
4. The native Windows XP system comes with a recovery function to avoid system crash caused by illegal
shutdown or misoperation.
5. Equipped with ultra-thin industrial keyboard and optical mouse, you can complete various operations
through the keyboard or mouse just like ordinary PC.
6. The main control board adopts DSP + FPGA structure and 16-bit DAC output. It can generate high-density
sine wave of 2000 points per week for the fundamental wave, which greatly improves the quality of the
waveform and the accuracy of the tester.
7. The power amplifier adopts high-fidelity linear power amplifier, which ensures the accuracy of small current
and the stability of large current.
8. This microcomputer relay protection tester adopts USB interface to communicate with PC directly without
any transfer wiring, which is convenient to use.
9. Can be connected to a laptop (optional) to run. The laptop and the industrial computer use the same set
of software, and there is no need to re-learn the operation method.
10. Equipped with independent dedicated DC auxiliary voltage source output, the output voltage is 110V (1A),
220V (0.6A). It is used for relays or protection devices that require DC working power.
11. With software self-calibration function, it avoids the need to open the case to calibrate the accuracy by
adjusting the potentiometer, thereby greatly improving the stability of accuracy.
