Automatic current generator for soft starter test.

A: the main functions and features:

1) built in the high allocation of industrial control machine, the programmable logic controller (PLC) as the central processor, to an AC signal for real-time scanning, to achieve a comprehensive monitoring and closed-loop control, and design password management, only to get corresponding authority to operate the personnel, in order to certain features of the operation.

2) imported PC color LCD touch screen operation, using the support of field bus technology intelligent sensor and realize the data transmission of full digital display operation unit selects touch type color LCD screen, full Chinese menu, the interface is clear and intuitive, the operation is simple and convenient. The test without any external auxiliary equipment, automatic control, fool operation, quick, simple and convenient

3) test method the instrument automatic test and manual test two methods, only need to set the test current and time can be simple. With automatic steady system, equipped with 2 USB ports, U disk, printer etc. easy plug-in devices. RS232 and RS485 two kinds of communication interface, can be connected with computer, can be directly connected with the computer through the RS232 interface PC communication,

4) just set a good target current can be, without the need for manual monitoring, only need to set up the test, the current and step, eliminates the need to manually adjust the pressure, artificial records, drawing curves, and so cumbersome labor, reduce labor intensity, improve work efficiency can also be after the end of the work to read data on the computer check can be.

There are 5) exceeds the limit value of the automatic alarm function has the advantages of reliable overheat, overcurrent and overvoltage protection circuit and self protection function. AC voltage protection device should be used in microcomputer automatic protection control and mechanical micro limit switch double protection, to ensure the normal work of constant current power supply, improve the safety and reliability of products.

6) human interface, friendly software interface, full Chinese operation interface, control software have data record, and the current, temperature waveform storage, data management, reports, such as printing a variety of practical function; parameter setting is completed in the software. A more intuitive analysis of the relationship between current and temperature. All the data and test results at a glance. During the test, automatic tracking automatic current, stable output current, automatically adjust the three-phase current; after completion of the test, automatically return to zero;

7) automatically adjust the AC constant current source to meet GB 7251.1 standard to standard GB 7251.5 low-voltage switch cabinet (multi output control cabinet containing such as GCK, MNS, etc.) the temperature rise test automatically adjust the AC constant current source in the temperature rise test implementation and constant current power supply and the machine is running, should be provided for users to use more than one constant current source and the machine is running the proof material copy pieces, such as MNS or GCK temperature rise test),

8) with three-phase automatic balancing system to ensure a balanced three-phase output, output current sampling imported Rogowski coil and the use of the new power electronic technology, strong anti-interference ability, high precision output, up to a maximum of 0.5 grade.

9) equipped with a precision adjustment menu, the user can adjust the error value. Programmable AC constant current power supply can realize intelligent correction in equipment can be tuned in range of automatic generation of multi section correction factor to ensure the constant current power supply current precision.

10) can display the three-phase full current curve and the 64 road temperature curve. Can bring a micro printer, can be on-site at any time to print the curve and test data

11) test report for the WORD format documents, the instrument can be edited, finishing, printing

12) can be customized according to user requirements test module, software for life free upgrade
