Need help?Do you have a question about the Borri B9000FXS 60kVA and is the answer not in the manual?
Converts AC input to DC voltage, feeding the inverter and charging the battery.
Converts DC input to AC voltage, stabilized in frequency and RMS value.
Handles non-linear loads by adjusting PWM generation to maintain output waveform.
Manages overload conditions by limiting output current and using thermal image algorithm.
Transfers load to emergency line or limits current during short-circuit.
Monitors inverter input current to detect and protect against IGBT bridge short-circuits.
Describes battery installation in external cabinets and charging logic.
Composed of thyristors, rated for continuous work, protecting bypass line components.
Transfer to emergency line due to faults like short-circuit or voltage out of tolerance.
Automatic switch back to inverter once it's working and synchronized.
Allows safe maintenance and repair of the unit by switching the load to bypass.
Rectifier supplies inverter & battery, inverter supplies load via static switch SSI.
Battery feeds inverter during mains/rectifier failure, with automatic restart options.
Load is fed via bypass line, either manually or automatically.
Used for checking functionality or during maintenance; load supplied directly by bypass mains.
