Product Performance

Control Performance: Equipped with Direct Torque Control (DTC) technology, it can realize precise control of motor speed and torque, with fast response and smooth operation. The output frequency is stably 0 to 75Hz, which can effectively optimize motor operation efficiency, reduce equipment mechanical stress, and adapt to the operation needs of different load conditions.

Adaptability Performance: It supports two configurations: direct grid connection (transformerless) or external isolation transformer. The “three-in three-out” wiring technology simplifies the installation process, can be directly adapted to standard induction motors without modifying the original motors, and is suitable for various medium-voltage industrial drive scenarios.

Safety Performance: It has complete overvoltage and overcurrent protection functions, integrates arc protection design and fuse-free structure, has strong anti-electromagnetic interference ability, and the input harmonics comply with international and domestic relevant standards, which can effectively protect the safe and stable operation of the inverter and associated motor equipment.

Stability Performance: Adopting mature multi-level topology and high-voltage IGBT power semiconductor technology, it has a small number of components and high reliability, with a long mean time between failures. It can operate stably for a long time within the ambient temperature of +1℃ to +40℃ and altitude of 2000m, without frequent failures.

Operation and Maintenance Performance: The modular design with extractable phase modules facilitates quick replacement and maintenance of components, and the mean time to repair is at the leading level in the industry; debugging operation is convenient, with clear operation status indicators, which can quickly troubleshoot faults and reduce daily operation and maintenance costs.

Energy-saving Performance: Integrating Active Front End (AFE) technology, it can realize four-quadrant operation, feed back braking energy to the power grid, and has reactive power compensation function, which can effectively reduce energy consumption, maintain stable grid voltage, and reduce reactive power fines.
