1. Intelligent host: The host adopts a high-speed and high-performance digital signal processor with fast processing speed and wide transmission bandwidth. The software applies a dual precision algorithm to generate high-precision waveforms for each phase. Due to the use of an integrated structure, the various parts are tightly combined, the data transmission distance is short, and the structure is compact.
2. Single machine independent operation: The device is operated by a convenient and flexible rotating mouse through a large LCD screen, with a full set of Chinese display. It can complete most of the on-site testing and verification work, and can verify various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection. It can also simulate various complex instantaneous, permanent, and conversion faults for whole group testing.
3. Connect to a computer for operation: Through the full set of Chinese operating software on the Windows platform, various large-scale, complex, and highly automated verification tasks can be performed. It is convenient to test and scan various protection settings, store test data in real time, display vector graphics, draw fault waveforms, and print reports online.

1.Large screen LCD display: This machine adopts a high-resolution graphic LCD display with a large screen. All operation processes are set on the display screen, and the operation interface and test results are displayed in Chinese, making the display intuitive and clear.

2.'Foolish' operation: using a controller to 'rotate the mouse' greatly simplifies the structure of the operation part, making the operation simple, fast, and easy to master.

3.New high fidelity power amplifier: The output stage adopts a new high-power modular high fidelity power amplifier component, which can be used for both current output and voltage output, with high output power, good accuracy, and high reliability.

4.Direct output of current and voltage: The phase voltage and phase current are output by a DC power amplifier, which can directly output AC voltage, AC current, DC voltage, and DC current, with variable angles and frequencies, and can superimpose 1-20 harmonics.

5.Self protection: adopting a reasonably designed heat dissipation structure, with reliable and comprehensive multiple protection measures, power soft start, and certain fault self diagnosis and locking functions.

6.Having independent dedicated DC power output: The device is equipped with one 110V or 220V dedicated DC power output.
