The medium-voltage frequency converters can be tailored to meet specific customer requirements (690V: 15-750kW, 1140: 45-1500kW), and find applications across diverse industries including mining, oilfields, construction, chemical industry, machine tools, textiles, ceramics, and ventilation systems.

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.
