1. Meets all the requirement of field tests. This tester with standard 4
phase voltage, 3 phase current output, voltage 125V/phase, current 30A/phase,
3 phases in parallel can up to 120A. Digital Signal Processor Microcomputer.
Not only test the traditional relays and protectors, but also test the modern
microcomputer relays, special for transformer differential protection and
transfer equipment.

2.All technical indicators fully meet the standard DL/T624-1997: Technical
condition of the relay computer test device.
3. Classic Windows 7 operating interface, friendly man-machine interface,
easy and fast to operate; High-performance embedded industrial control
computer and 8.4-inch resolution of 800 × 600 TFT true color display which
provides rich visual information, includes the current working condition and
all kinds of help information.

4. The Windows 7 system comes with the restore function; avoid system crashes
caused due to illegal shutdown, or malfunction, etc.

5. Equipped with ultra-thin industrial keyboard and optical mouse, complete a
variety of operations using keyboard or mouse the same as ordinary PC.

6. The main control board is DSP + FPGA architecture, 16 bit DAC output,
generates high - density sine wave 2000 points each circle to fundamental
wave, which greatly improve the wave quality and the accuracy of the test
instrument.

7. Using high-fidelity linear amplifier. Both to ensure the accuracy of a low
current, but also guarantee the stability of the high current.

8. USB directly connect with PC, without any adapter cable, easy to use.

9. Can be connected to a laptop computer (Optional). Laptop computers and
industrial machines use the same software, no need to re-learn the methods of
operation.

10. With a separate DC auxiliary voltage source, output voltage 110V(1A),
220V(0.6A), provides relays or protective devices which require DC power.

11. The software with self-calibrating function, which avoid to calibrate
accuracy by adjusting relays after open the case, greatly improve the
stability of the accuracy.
