The Kinco KC200 series universal vector frequency converter features comprehensive and reliable protection and performance optimisation capabilities.
Its protective functions encompass overcurrent suppression protection (continuously monitoring current and automatically limiting it below the overcurrent suppression threshold), overvoltage suppression protection (when no braking resistor is connected, automatically adjusting operating frequency or employing magnetic braking to prevent overvoltage protection triggering due to excessive bus voltage), undervoltage suppression protection (supporting uninterrupted operation during momentary power outages), and wave-by-wave current limiting protection (restricting current rise during abnormal events like sudden load changes or transient current spikes to prevent overcurrent shutdowns).
Additionally equipped with overvoltage and overcurrent fault protection, it detects input phase loss based on bus voltage fluctuations (requires certain load conditions), rapidly identifies output phase loss before and after operation, and swiftly recognises phase-to-phase short circuits and ground faults within 10 milliseconds prior to operation.
Further protection mechanisms address inverter module overheating, parameter self-learning failure, current detection faults, and SVC stall faults. Regarding thermal management, this series employs an independent air duct design positioned close to the IGBT power devices for efficient heat dissipation. Software incorporates an automatic carrier frequency reduction function based on temperature rise.
In application scenarios, the KC200 series is widely applicable for driving equipment in industries such as textiles, machine tools, packaging, and food processing, as well as for fans, pumps, and various automated production machinery.
