I. Overview (Features)
u Flexible combination of voltage and current outputs Outputs up to 6 phases of voltage and 6 phases of current, which can be arbitrarily combined to achieve conventional 4-phase voltage and 3-phase current, 6-phase voltage, 6-phase current, and 12-phase output modes. It is compatible with various traditional test methods and can conveniently perform three-phase transformer differential tests, auxiliary power fast switching, and busbar automatic transfer switch tests.
u Operation mode The device is directly connected to an external laptop or desktop computer for operation, which is convenient and fast, with stable performance.
u New high-fidelity linear power amplifier The output stage consistently uses high-fidelity, high-reliability modular linear power amplifiers, rather than switching-type amplifiers, ensuring excellent performance. It does not generate high or medium frequency interference at the test site, and guarantees smooth waveforms with excellent accuracy from large currents to tiny currents.
u High-performance host The output part is controlled by DSP, with fast computation speed, strong real-time digital signal processing capability, wide transmission bandwidth, and high-resolution D/A conversion control. The output waveform has high accuracy, low distortion, and good linearity. A large number of advanced technologies and precision components are used, along with professional structural design, resulting in a compact, lightweight, fully functional, and portable device that can work immediately upon power-on, making field testing very convenient.
u Powerful software functions It can complete various highly automated large-scale complex calibration tasks, conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector diagrams, and print reports online. The 6-phase current can conveniently perform three-phase differential protection tests.
u Independent dedicated DC power output It is equipped with a 110V and 220V dedicated adjustable DC power output.
u Complete interfaces The device has a USB communication port, which can communicate with computers and other external devices.
u Comprehensive self-protection functions The heat dissipation structure is reasonably designed, hardware protection measures are reliable and complete, with soft-start power supply function, software self-diagnosis of faults, and output blocking functions.
