武漢摩恩智能電氣有限公司

一.Main characteristics

1.Meets all the requirement of field tests. This tester with standard 6

phase voltage， 6 phase current output， voltage 125V/phase， current

30A/phase， 6 phases in parallel can up to 180A. Digital Signal Processor

Microcomputer. Not only test the traditional relays and protectors， but

also test the modern micro computer relays， special for transformer

differential protection and transfer equipments

2.All technical indicators fully meet the standard DL/T624-1997:

Technical condition of the relay computer test device.

3.Classic Windows XP 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 XP 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.
