①Built in high configuration industrial computer：

Adopting programmable controller SiemensAs the central processor, PLC performs real-time scanning of AC signals to achieve comprehensive monitoring and closed-loop control, and is designed with password setting management. Only personnel with corresponding operating permissions can perform certain functional operations.

②ImportPC genuine color 10.0-inch large LCD touch screen operation：

Adopting intelligent sensors that support fieldbus technology, data transmission is fully digitized. The display and operation unit adopts a touch sensitive color LCD screen, with a full Chinese menu and clear and intuitive interface, making operation simple and convenient. Testing does not require any external auxiliary equipment, fully automatic control, foolproof operation, fast, simple, and convenient

③There are two testing methods: fully automated testing and manual testing：

Just set a simple test current and time. Equipped with an automatic current stabilization system.

④Fully automatic operation:

Just set the target current, no manual monitoring is required, only the testing, current, and step size need to be set, saving tedious labor such as manual voltage adjustment, manual recording, and curve drawing, reducing labor intensity, and improving work efficiency. After the work is completed, the data can be read to the computer for viewing.

⑤Self protection mechanism:

The automatic alarm function for exceeding the limit value has reliable self-protection functions for overheating, overcurrent, overvoltage, and short circuit. The protection of the AC voltage regulating device should adopt dual protection of microcomputer automatic protection control and mechanical micro limit switch to ensure the normal operation of the constant current power supply and improve the safety and reliability of the product.

⑥人性化界面：

The software interface is user-friendly, with a fully Chinese operating interface. The control software has multiple practical functions such as data recording, storage of current and temperature waveforms, data management, reporting, printing, etc; All parameter settings are completed in the software. More intuitively analyze the relationship between current and temperature. Make all data and test analysis results clear at a glance. During the experiment, the target current is automatically tracked, the output current is automatically stabilized, and the three-phase current is automatically adjusted; After the experiment is completed, it will automatically return to zero position;

⑦automatic adjustmentFunction:

Automatic adjustment of AC constant current source to meet the requirementsThe temperature rise test of the complete set of medium and low voltage switchgear (including control cabinets with multiple outputs such as GCK, MNS, etc.) according to GB 7251.1~GB 7251.5 standards should be able to achieve parallel operation of multiple constant current power sources during the temperature rise test with automatic adjustment of the AC constant current source (copies of proof materials for users using multiple constant current sources for parallel operation, such as GCK or MNS temperature rise test)

⑧System:

Equipped with a three-phase automatic balancing system to ensure three-phase balanced output, the output current sampling adopts0.2S level transformer, adopting the latest power electronics technology, with strong anti-interference ability and high output accuracy, up to 0.5 level.

⑨user-friendly design

Equipped with a precision adjustment menu, users can adjust the error value themselves. The program-controlled AC constant current power supply can achieve fully intelligent calibration, automatically generating multiple calibration coefficients within the adjustable range of the equipment to ensure the stability accuracy of the constant current power supply.

⑩Software upgrade:

Test modules can be customized according to user requirements, and software can be upgraded for free for life

⑪Built in power compensation system
