Features :

1. Intelligent host, the host uses a high-speed and high-performance digital signal processor with fast computing speed and wide transmission bandwidth. It can generate a high-density fitting sine wave with 360 points per cycle for the fundamental wave. This is the highest level among similar output methods at present. Due to the large number of points, the fidelity of the waveform is extremely high and the distortion is extremely small, especially when the harmonic output is in progress, even for the 9th harmonic and 300Hz, it can reach a high density of 60 points per cycle. 2. The single machine runs independently, and the device is operated by a convenient and flexible rotating mouse through a large-screen LCD display, with a full set of Chinese displays. It can complete most of the on-site test and verification work, and can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low frequency, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and can simulate various complex transient, permanent, and conversion faults for a whole set of tests.
2. Connect to computer and run through a full set of Chinese operating software on Windows XP platform, which can carry out various large-scale, complex and more automated calibration work, conveniently test and scan various protection settings, store test data in real time, display vector diagrams, draw fault waveforms, print reports online, etc.
3. 16-bit DAC chip, 16-bit high resolution ensures high accuracy of fitting waveform and good linearity. Small signal output also guarantees minimal distortion.
4. Large LCD display screen This machine adopts a 320×240 dot matrix large-screen high-resolution graphic LCD display screen. All operation processes are set on the display screen. The operation interface and test results are displayed in Chinese, and the display is intuitive and clear.
5. The "fool-style" operation adopts the advanced controller "rotating mouse", which greatly simplifies the structure of the operation part, making the operation simple, fast and easy to master.
6. The new high-fidelity amplifier uses a new high-power modular high-fidelity amplifier component at the output stage, which can be used for both current and voltage output. The output power is large, and the voltage of each phase can be up to AC100V/120V (803), and the current three-phase output can be up to AC90A/120A (803)/180A (803-60A). It has good precision and high reliability.
7. Current and voltage direct output Phase voltage and phase current adopt DC power amplifier output mode, which can directly output AC voltage, AC current, DC voltage and DC current, and can change the angle and frequency, and can superimpose 0-9 harmonics.
8. Self-protection, adopting a reasonably designed heat dissipation structure, with reliable and complete multiple protection measures and power soft start, and certain fault self-diagnosis and locking functions.
9. Rich in contacts, with 11 contact inputs and 8 empty contact outputs. The input contacts are compatible with empty contacts and 0-250V potential contacts, and can be intelligently and automatically identified.
10. The main unit is integrated into a single chassis structure, and can be powered by AC 127V/220V. It can be turned on and work immediately. It is small in size, light in weight, easy to carry, and convenient for flow testing.
11. High cost performance, it is a cross-disciplinary joint design product, integrating the advanced scientific and technological achievements of multiple disciplines. It has the performance of a large tester and the price of a small tester, and has a high performance-price ratio.
