Microcomputer Harmonic Elimination Device
Functions and Features
●Modular design, compact structure, advanced technology, high-speed 32-bit ARM core processor ensures real-time operation and action accuracy.
●Real-time monitoring of system status, real-time calculation, accurate judgment of low-frequency, fundamental frequency, high-frequency resonance faults in the system, and timely action.
●Real-time display of three-phase voltage, opening voltage, can accurately determine grounding, overvoltage and undervoltage, resonance.
●If the resonance of the system is eliminated by damping, if it is excited again, the device can be restarted immediately to eliminate it.
●Industry standard RS-485 communication interface, can transmit the running status of the system to the upper computer in real time.
●Fault recall function, large-capacity Flash memory saves the last 30 historical fault records.
●With good electromagnetic compatibility, it is suitable for application in complex environment with strong electromagnetic interference.
●Dual hardware watchdog circuit ensures the reliability of software operation.
●Chinese LCD display, clear running status, menu-based operation, easy to use.
