Product Description

Advantage

1.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. 8.4"LVDS  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.

2.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.

3.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.

4.Voltage and Current Amplifier
-For phase current and voltage, we persist in adopting high performance linear amplifier output mode in order to make the current and voltage   source to directly output all kinds of waveforms from the DC waveform to the waveforms including all kinds of frequency components, such as   square wave, combined waveform overlapped by each order harmonic, fault transient waveform, etc. In addition, the output waveform is clear and   smooth without high-frequency radiated interference with neighboring equipments. It can simulate well all kinds of current and voltage   characteristics under the circumstance of short circuit fault.
-For power amplifier circuit, we adopt import power parts with high-power and hi-fi module style as power output, combining with heat dissipation   structure layed elaborately and reasonably, it has enough large power redundancy and thermal capacity. The power amplifier circuit has overheat,   overflow, overvoltage and short circuit protections. When overflow occurs in the current circuit and overload or short circuit occurs in the voltage   circuit, it will limit the output power automatically, switch off the whole power amplifier circuit and give alarm signal.In order to prevent the overheat   of the power amplifier for long time operating under large current, a software time terminating system under large current is set in this tester. It can   work for a long period when outputting is 10A or below. When the current is over 10A, the tester will start up the software time termination order.   When time is up, the software will forbid power output automatically and give alarm signal. The higher output current is, the shorter the limiting time   will be.

5. Digital Input and output
-This tester has 8 channels digital input and 4 channels output, please refer to the corresponding instruction to hardware structure of 702 " Tester.
-The switching input circuit is compatible for both the empty contacts and 0-250V electric potential contacts in the input and output circuit. When the   electric potential contacts are selected, 0-6V belongs to closed switch and 11-250V belongs to open switch. The switching capacity can test   the action time and the action time interval of every phase switch's contact conveniently.
-The part of the digital input is isolated from the resources of the mainframe and the amplifier. The end of the digital input is hung, so the common   end of the digital input is separated from the Common End UN, IN of current and voltage parts.
-Switching potential input has directivity, you should connect the common end with the positive terminal of potential, and connecting the input end   with negative terminal of potential for ensuring the potential of common end is higher than the one of input end. In practice, you should connect the   input common end with +KM, and connecting the negative terminal of contact with input end.
-The output part is the idle contact output of relay. Output capacity is DC:220V/0.2A,AC:220V/0.5A. Output of switching capacity is independent of   voltage, current, input and all other parts. Action process of each digital output part is different in each testing module. For details, please refer to   the operation instruction on software module.
-The connection diagram of two kinds of familiar digital output is as follows:
                                               
Mode of potential contact

                                                                                                 
Mode of free contact


6. 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. We still set a potentiometer for this power supply, it can be adjusted within the range of 80%-110%. 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.
