Key Features

Flexible Voltage and Current Output Combinations:** Capable of outputting up to 6 phases of voltage and 6 phases of current, the unit allows for arbitrary combinations to realize standard output modes—including 4-phase voltage/3-phase current, 6-phase voltage, 6-phase current, and 12-phase configurations. This versatility not only ensures compatibility with various traditional testing methods but also facilitates convenient testing for 3-phase transformer differential protection, as well as plant auxiliary power fast transfer and automatic transfer switch (ATS) schemes.

Operation Mode:** The device connects directly to an external laptop or desktop computer for operation, offering a convenient, fast, and stable user experience.

Novel High-Fidelity Linear Power Amplifier:The output stage consistently employs high-fidelity, high-reliability modular linear power amplifiers—rather than switching-type amplifiers—delivering exceptional performance. This design eliminates high- and medium-frequency interference at the test site and ensures smooth waveforms with excellent accuracy across the entire output range, from high currents down to minute currents.

High-Performance Main Unit:The output section is controlled by a DSP, featuring rapid processing speeds, robust real-time digital signal processing capabilities, wide transmission bandwidth, and high-resolution D/A conversion control. The resulting output waveforms exhibit high precision, minimal distortion, and excellent linearity. By incorporating numerous advanced technologies, precision components, and a specialized structural design, the device achieves a compact size, light weight, comprehensive functionality, and easy portability; it is ready for immediate operation upon power-up, making it ideal for mobile field testing applications.

Powerful Software Functionality:The software enables the execution of various large-scale, complex calibration tasks with a high degree of automation. It facilitates the convenient testing and scanning of various protection settings, fault playback, real-time storage of test data, vector diagram display, online report printing, and more. The 6-phase current output capability is specifically designed to facilitate comprehensive testing of 3-phase differential protection systems.

Independent Dedicated DC Power Output:** The unit features a dedicated, adjustable DC power output channel offering both 110V and 220V options.

Comprehensive Interface:The device is equipped with a USB communication port, enabling seamless communication with computers and other external peripherals.

Comprehensive Self-Protection Features:The unit features a rationally designed heat dissipation structure and robust, reliable hardware protection measures. These include a power supply soft-start function, software-based fault self-diagnostics, and output interlocking capabilities to ensure safe and reliable operation. Section 2: Rated Parameters
