Microcomputer Relay Protection Calibration Device Features
1. Uses the easy-to-use Windows XP operating system, with a friendly human-machine interface and quick and simple operation. To facilitate user use, a large number of keyboard shortcuts are defined, making operation "one-key to the point".
2. High-performance embedded industrial control computer and large-screen high-resolution color TFT LCD display can provide rich and intuitive information, including the current working status of the device, next-step work prompts, and various help information.
3. Equipped with an ultra-thin industrial keyboard and touch mouse, various operations can be completed through the keyboard or mouse just like operating a normal PC.
4. Equipped with an external USB interface, convenient for data storage and software maintenance.
5. All project tests can be completed without external devices, with automatic display and recording of test data, and drawing of vector diagrams and characteristic curves.
6. Uses high-performance D/A converters, producing waveforms with high precision and good linearity, and possessing good transient response and amplitude-frequency characteristics. Waveform accuracy and other indicators can be guaranteed throughout the entire measurement range.
7. Can directly output AC voltage, AC current, DC voltage, and DC current, with variable amplitude, phase angle, and frequency.
8. The power amplification part adopts a new type of high-power high-fidelity linear power amplifier circuit, with large output power and low ripple interference. Even when the output current reaches the maximum, the waveform can still be guaranteed without distortion or peak clipping.
9. The binary input interface can automatically adapt to passive (dry contact) and active inputs, and can automatically adapt to the polarity of active inputs, working normally within the input voltage range of ±250V.
10. Comes with a 110V/220V auxiliary DC power supply, which can power protection devices at the test site.
11. Can complete various complex calibration tasks, conveniently test and scan various protection settings, store test data in real-time, display vector diagrams, print reports, etc.
12. Adopts a carefully designed chassis structure, small size, good heat dissipation, light weight, easy to carry, and convenient for mobile testing.
13. The instrument has self-protection functions, adopts a reasonably designed heat dissipation structure, has reliable and complete multiple protection measures, supports output waveform monitoring, and certain fault self-diagnosis and blocking functions.
