High-Performance Industrial Control Computer
High performance Industrial control computer is adopted as the controlling computer, through which you can run the windows operating system directly. 6.4"TFT true color LCD display, tracking ball and optimized keyboard are allocated on the faceplate of this tester, which can be used without the external mouse and keyboard. USB interface, 10-100M net mouth and serial communication interface are located on the back plate of this tester, through which you can access data, communicate data and upgrade software conveniently.
The whole process and the result of the test will all be showed on the LCD. The English operational interface of the complete set is very friendly and convenient. The tracking ball and keyboard on the faceplate will implement the operation. The operation is simple and convenient, and is easy to be mastered. Operator only needs a little knowledge of computer.
Keyboard and mouse interface are also allocated on the faceplate. If you would like to use the external mouse and keyboard, through pluging them with corresponding interfaces, you can operate this tester just like operate a desk-top computer.
1、Meet all field test requirements.The Microcomputer relay protection tester has the standard four phase voltage three phase current output voltage125V/phase phase current a / 40.Three-phase parallel connection up to 120A.It can be used not only for traditional relays and protection devices but also for modern microcomputer protection especially for transformer differential power protection and backup automatic switching device which makes the test more convenient and perfect.
2、All kinds of technical indexes have reached the standard of DL/ t624-1997 "technical conditions of microcomputer test equipment for relay protection" issued by the ministry of electric power.
3、Classic WindowsXP operation interface man-machine interface friendly easy and quick to operate;The high-performance embedded industrial control computer and 8.4-inch TFT true-color display with a resolution of 800×600 provide rich and intuitive information including the current working status of the device and various help information.
4、Relay protection device (testerWindows XP) has built-in recovery function to avoid system crash caused by illegal shutdown or misoperation.
5、Equipped with an ultra-thin industrial keyboard and photoelectric mouse it can complete various operations through the keyboard or mouse just like the operation of ordinary PC.
6、The main control board adopts DSP+FPGA structure and 16-bit DAC output which can generate high-density sinusoidal wave of 2000 points per week for the basic wave greatly improving the quality of waveform and improving the precision of tester.
7、High-fidelity linear power amplifier ensures the accuracy of small current and the stability of large current.
8、Use USB interface to communicate directly with PC without any connection easy to use.
9、Connect to laptop (optional) to run.Laptop computer and industrial computer use the same set of software no need to learn how to operate.
10、It is equipped with the independent auxiliary voltage source output the output voltage is 110V(1A) and 220V(0.6a) respectively.To be used by relays or protective devices that require dc operating power.
11、With the software self-calibration function it avoids the need to open the chassis and adjust the potentiometer to calibrate the precision thus greatly improving the stability of the precision.
