  • ■  Intelligent host machine: Host machine adopts high speed and performance digital signal processor. It has the advantages of top-speed calculating speed, wide transmission band, and it adopts dual-precision algorithm on software to produce high precised waveform. Due to the integrated structure, every parts combines tightly, so as the data’s transmission distance is short, and the structure is compact.
    ■  
    Independent operating stand-alone: Adopting flexible rotating mouse to operate through large screen LCD, displayed entirely in Chinese. Except detecting various relay protection testers ( such as current, voltage, IDMT, power direction, impedance, differential, low-cycle, simultaneous, frequency, DC and time etc) and microcomputer protection, it can also simulate instantaneous, permanent and transformational faults to test.
    ■ 
    Operation online: Through the whole operating software in Chinese on the Windows platform, it can finish all kinds of large-scale and complicated checkout work with high automatic level. This will be convenient to test and scan various protective definite value, to carry out bug playback, to store testing data in the real time, to display vector diagram and to print report online.
    ■  
    Large LCD screen: This machine adopts large LCD screen with high resolution ratio, so the whole operating process can be set on the screen. The operating interface and testing results are all visually displayed in Chinese.
    ■  
    Automatic miniature operation: By adopting the advanced controller “ rotating mouse”, it greatly simplified operating structure, made it easy and convenient to grab.
    ■  
    Brand new high fidelity power amplifier: We always insist on adopting high fidelity and reliable modular power amplifier to make output. It suits for both current output and voltage output. High output power and precision.
    ■  
    Direct output of current&voltage: The phase voltage and phase current all adopts DC-type’s power amplifier output way. This can directly output AC voltage&current, DC voltage and DC, and it can also change the angel and frequency, overlying the harmonic wave for 2~20 times.
    ■  
    Self-defense function: Reasonable design with heat dissipation structure, reliable and impeccable hardware protective measures. Equipped with soft start function of power supply, fault self-diagnostic function of software and latching function of output.
    ■  
    Independent DC power supply: Equipped with one-route special DC power supply output of high power 110V or 220V.
    ■  
    Abundant contacts: 7 routes for contact input while 2 routes for idle contact output. The input contact is compatible for idle contact and 0~250V potential contact. It’s also of intelligent automatic identification function.
    ■  
    Integrated stand-alone structure of host machine: Adopting 220V AC power supply, it has the features of small volume, light weight and easy to take. Convenient for flow test.
    ■  
    High cost performance: It’s belonging to transdisciplinary joint-design product, synthesized a lot of professional advanced technical achievements. Both equipped with the performance of large-scale tester and price of small sized tester, it’s of high cost performance.

     

  • ■ Except detecting various relay protection testers ( such as current, voltage, IDMT, power direction, impedance, differential, low-cycle, simultaneous, frequency, DC and time etc) and microcomputer protection, it can also simulate instantaneous, permanent and transformational faults to test from single-phase to three-phase. Moreover, it can finish all kinds of large-scale and complicated checkout work with high automatic level. This will also be convenient to test and scan various protective definite value, to carry out bug playback,to store testing data in the real time, to display vector diagram, to print report online and to test ATS, fast cutting and system shock etc.
