■ Features

▲ Built-in high-configuration industrial computer, using programmable controller Siemens PLC as the central processor, real-time scanning of AC signals, realizing comprehensive monitoring and closed-loop control, and designing password setting management. Only personnel with corresponding operating rights can perform certain The operation of these functions.

▲Imported PC real-color 10.0-inch large LCD touch screen operation, using intelligent sensors that support fieldbus technology to achieve full digital data transmission, the display operation unit uses a touch-type color LCD screen, full Chinese menus, clear and intuitive interface, The operation is simple and convenient. The test does not require any external auxiliary equipment, fully automatic control, fool-like operation, fast, simple and convenient.

▲ The test method of this instrument has two methods: automatic test and manual test. You only need to set a simple test current and time. With automatic steady flow system.

▲ You only need to set the target current without manual monitoring. You only need to set the test, current and step length, eliminating the tedious labor of manual voltage adjustment, manual recording, and curve drawing, reducing labor intensity and improving work efficiency. After the work is over, you can read the data to the computer for viewing.

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

▲Humanized interface, friendly software interface, all-Chinese operation interface, control software has data recording, and can store current and temperature waveforms, data management, reports, printing and other practical functions; parameter settings are all completed in the software. Analyze the relationship between current and temperature more intuitively. Make all data and test analysis results clear at a glance. During the test, the target current is automatically tracked, the output current is automatically stabilized, and the three-phase current is automatically adjusted; after the test is completed, it automatically returns to the zero position.

▲ Automatically adjust the AC constant current source to meet the GB 7251.1 ~ GB 7251.5 standard medium and low voltage switchgear (control cabinets containing multiple outputs such as GCK, MNS, etc.) temperature rise test, and automatically adjust the AC constant current source should be able to perform the temperature rise test Realize the parallel operation of multiple constant current power sources in the process (a copy of the proof material for the user to use multiple constant current sources to operate in parallel, such as the temperature rise test of GCK or MNS, etc.).

▲ With a three-phase automatic balance system to ensure three-phase balanced output, the output current sampling adopts 0.2S class transformer and the latest power electronic technology, with strong anti-interference ability and high output accuracy, up to 0.5 level.

▲ Equipped with a precision adjustment menu, users can adjust the error value by themselves. The programmable AC constant current power supply can realize full intelligent calibration, and automatically generate multi-segment correction coefficients within the adjustable range of the device to ensure the constant current power supply accuracy.

▲ The test module can be customized according to user requirements, and the software can be upgraded for free for life.
