Product Features
◆Standard 4-phase voltage and 3-phase current output With 4-phase voltage and 3-phase current output, various combined outputs can be conveniently performed for various types of protection tests. The maximum output for single-phase voltage is 120V, and the maximum output for single-phase current is 40A (10 seconds). The three-phase current can be paralleled to output up to 120A. The 4th phase voltage Ux is a multifunctional voltage item, which can be set to output 4 types of 3U0 or synchronization voltage, or any arbitrary voltage value.
◆Convenient standalone operation The standalone unit is operated via a flexible rotating mouse through a large LCD screen, with all displays in Chinese. It can complete most on-site test and verification work, verify various relays and microcomputer protections, and simulate various complex transient, permanent, and conversion faults for whole-set tests. It is ready to use upon power-on, with quick and convenient operation.
◆Dual operation modes, connectable to a computer Through a full set of Chinese operation software on the Windows platform, it can perform various large-scale, complex, and highly automated calibration tasks. It can conveniently test and scan various protection settings, store test data in real-time, display vector diagrams, plot fault waveforms, and print reports online.
◆Powerful software functions It can complete various large-scale and complex calibration tasks with high automation, such as three-phase differential tests, auxiliary power fast switching, standby power supply automatic switching tests, line protection synchronization reclosing, etc. It can conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector diagrams, and print reports online.
◆Rich switch quantity contacts It provides 7 contact inputs and 2 pairs of dry contact outputs. The input contacts are compatible with both dry contacts and 0~250V potential contacts, with intelligent automatic recognition. Input and output contacts can be expanded according to user needs.
◆Large LCD screen This unit adopts a 320×240 dot-matrix large-screen high-resolution graphic LCD. All operation processes are set on the screen, and the operation interface and test results are displayed in Chinese, with intuitive and clear display.
◆Self-protection It adopts a reasonably designed heat dissipation structure, and has reliable and comprehensive multiple protection measures, power soft-start, and certain fault self-diagnosis and blocking functions.
◆Independent dedicated DC power output The device is equipped with one 110V and one 220V dedicated DC power output.
◆High cost-performance ratio It is a cross-disciplinary joint design product, integrating advanced scientific and technological achievements from multiple disciplines. It combines the performance of large-scale test instruments with the price of small-scale test instruments, offering a very high performance-price ratio.
