Core Description
The instrument provides a four-phase voltage output and three-phase current output (six-phase voltage output and six-phase current output). It can be used to test a wide range of conventional relays and protection devices, as well as modern microcomputer-based protection systems—particularly transformer differential protection and standby automatic transfer switching devices. The testing process is more convenient and provides improved performance.

Introduction
1. A classic Windows XP operating interface with a user-friendly human–machine interface for simple, fast operation. High-performance embedded industrial control computer with an 8.4-inch TFT true-color display (800 × 600) to provide rich, intuitive information, including the equipment’s current operating status and various help screens.
2. The native Windows XP system includes a recovery function to prevent system crashes caused by improper shutdowns or misoperations.
3. Equipped with an ultra-thin industrial keyboard and a photoelectric mouse. Various operations can be performed via keyboard or mouse, similar to a standard PC.
4. The main control board uses a DSP + FPGA architecture and provides 16-bit DAC output. It can generate 2,000 high-density sine wave samples per week for the fundamental component, improving waveform quality and tester accuracy.
5. The power amplifier adopts a high-fidelity linear power amplifier. This ensures accuracy for small currents and stability for large currents.
6. USB interface communication with a PC directly, without requiring any adapter cable, for convenient use.
7. Optional laptop operation support. The notebook computer and industrial computer use the same set of software, so users do not need to learn a new operating method.
8. GPS synchronization test function. The device can be equipped with an optional built-in GPS synchronization module/card. Using an RS232 connection to a PC enables synchronous adjustment testing between two testers located in different places.
9. Includes an independent, dedicated DC auxiliary voltage source output. The output voltages are 110V (1A) and 220V (0.6A), respectively. It can be used for relays or protection devices that require a DC working power supply.
10. Software self-calibration function. This avoids opening the chassis and calibrating accuracy by adjusting potentiometers, significantly improving accuracy stability.
