Product Description

three phase relay protection tester price 

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.

Digital Signal Processor Microcomputer
High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced. Since integrative structure is adopted,the structure of the tester is layed compactly.The distance of data transmission is short with tight structure, which overcome the problem of fewer points of waveform output due to long data communicational line and narrow frequency band when using the test controller controlled directly by PC.

D/A Conversion and Low-Pass Filtering
High precision D/A converter is employed for ensuring the precision and linearity of current and voltage in the whole range.
Due to high density of fitting ponit, fidelity of waveform is high and harmonic component is small, which don't have a strict requirement on the low-pass filter. Consequently, it has good characteristics of transient, phase frequency and amplitude frequency, which is easy to perform accurate phase-shifting and harmonic superposition and ensures very high precision even when the frequency is high.

Auxiliary DC Power Supply Output for Special Use
A circuit of special adjustable DC power supply output is allocated on the rear panel, which has 110V and 220V two shifts that can be used as test standby power supply on the spot. Rated current of this power supply is 1.5A, which can be used as DC power supply of protective tester or switch loop supply. If overload or short circuit occurs, corresponding protector tube will be burned out (2A/250V), you will only need to change this protector tube at that time.
