The C919 series is a high-performance general-purpose vector frequency converter developed based on current market demands. It features a narrow body design, occupying minimal installation space, with high overall protection level and excellent performance in all aspects. It also offers ample expansion capabilities to fully meet market requirements. Its application areas include mining, oil fields, construction, chemical industry, lathe operations, textile industry, ceramics industry, and fans.

Reliability:

• The entire range of products undergoes benchmarking against the national standard open-level EMC testing standards and has obtained CNAS certification, along with a certification registration number.
• The product's long-term reliable operation is ensured through a substantial margin of safety, rigorous testing and verification procedures, the selection of high-quality components, and meticulous process management.
• The complete product range utilizes a packaged IGBT module solution, effectively guaranteeing product uniformity and minimizing potential quality issues.
• The implementation of three-phase current sampling enables precise torque control while effectively safeguarding against overcurrent, short circuits, and ground faults.
• The product is equipped with a comprehensive switch power supply protection design to ensure its stability even in the face of instantaneous or continuous short-circuits of the auxiliary power supply.
• The product is equipped with German Peters' original imported three-coat paint, which undergoes two coating processes to ensure reliable operation in complex environments.

Structural attributes:

• Enhanced with a straight-through independent air duct and space isolation, this design maximizes heat dissipation capability while supporting multi-machine side-by-side compact installation.
• The entire series showcases DC high-speed fans, renowned for their extended lifespan and effortless replacement.
• The optional dust cover and dust net (supporting quick installation) can effectively mitigate the impact of dust and moisture on the product.
• The models with a power output of 160KW or higher support cabinet mode, enabling efficient and cost-effective assembly of cabinets.

 Software Features:

• Featuring V/F, open-loop vector, closed-loop vector, pressure-frequency separation, and other control modes, our software performance has been deeply optimized to be suitable for a wide range of application environments.
• The system supports both static and dynamic self-learning modes, facilitating rapid and accurate acquisition of motor parameters.
• When power is applied, the power output line (including the motor) undergoes automatic grounding checks, thereby providing comprehensive protection for both the inverter and motor.
• The speed tracking function has been optimized to support both one-to-one and one-to-many tracking startups, effectively reducing the surge current during startup.
• The incorporation of an over-current and over-voltage rapid suppression function guarantees uninterrupted operation in the event of load fluctuations.
• The support for parameter copying facilitates efficient batch debugging of environments with similar functional requirements.

Extended Features:

• The system supports various types of signals, including differential signal, open-collector signal, and other encoder signals.
• The device supports isolation input for 2/3 channels of analog voltage ranging from 0 to 10V.
• The device supports isolation input for 2/3 channels of analog voltage ranging from 0 to 1A.
• The device supports 2/3 channels of isolated analog voltage/current input, with a range of 0~10V or 0~1A combination.
• A programmable I/O expansion card will soon be available, which can replace small PLCs and effectively reduce the system cost for customers.
