l Classic Windows XP operating interface, user-friendly, simple and quick operation. To facilitate user use, a large number of keyboard shortcuts are defined, making operation "one-key to the point";
l High-performance embedded industrial control computer and 8.4" large-screen high-resolution color TFT LCD display, providing rich and intuitive information, including the current working status of the device, next-step operation prompts, and various help information;
l Equipped with an ultra-thin industrial keyboard and optical mouse, all operations can be completed via keyboard or mouse just like operating a regular PC;
l Equipped with an external USB interface for convenient data storage and software maintenance;
l Without external equipment, it can complete testing of all items, automatically display and record test data, and draw vector diagrams and characteristic curves;
l Uses high-performance D/A converter, producing waveforms with high precision and good linearity, and has good transient response and amplitude-frequency characteristics. Waveform accuracy and other specifications are guaranteed throughout the entire measurement range;
l Uses a unique algorithm to produce accurate waveforms, completely different from curve-fitting waveform generation methods, ensuring the signal is a pure sine wave;
l Can directly output AC voltage, AC current, DC voltage, DC current, with variable amplitude, phase, frequency, and 2 to 40 harmonics;
l The power amplification section uses a new type of high-power, high-fidelity linear power amplifier circuit, with large output power and low ripple interference. Each phase voltage can output 120V, and current can output 40A. When the output current reaches 40A, the output power can exceed 450VA per phase, and the waveform remains undistorted and unclipped;
l In addition to the traditional Ua, Ub, Uc, Ia, Ib, Ic, it also provides a fourth voltage output Ux. Ux can be used for multiple functions, such as outputting various 3Uo, or outputting the synchronization voltage for line protection tests;
l Has 8 binary inputs and 4 pairs of dry contact outputs. The binary input interfaces can automatically adapt to passive (dry contact) or active inputs, and automatically adapt to the polarity of active inputs, working normally within an input voltage range of ±250V;
l Provides various automatic test software modules and GPS synchronous trigger test (optional);
l GPS synchronization trigger error is less than 50μS;
l Can complete various complex calibration tasks, conveniently test and scan various protection settings, and perform fault replay. Test data can be stored in real-time,
l Adopts a carefully designed chassis structure, small size, good heat dissipation, light weight, easy to carry, convenient for mobile testing;
l The instrument has self-protection functions, adopts a reasonably designed heat dissipation structure, and has reliable and comprehensive multiple protection measures and power soft start, as well as certain fault self-diagnosis and blocking functions.
