The mining explosion-proof medium and high voltage frequency converter adopts an integrated design, using a power unit in a series of multiple frequency converter topologies, allowing it to directly drive the motor without the need for an output filter.

The explosion-proof and intrinsically safe variable frequency drive for mining is a brand new generation of explosion-proof variable frequency drives. It features powerful functions, a complete range of models, a compact structure, and high cost-effectiveness. It can adapt to various complex working conditions and can also be deeply customized according to user needs.

The high-voltage solid-state soft starter product utilizes "step-variable frequency and stepless voltage regulation" technology, aimed at addressing the electrical and mechanical shock issues that arise during the startup process of medium and high-voltage AC motors. The device employs high-voltage thyristor series technology and fully digital control technology, featuring comprehensive motor protection functions. It is a new generation of high-tech high-voltage motor soft starter equipment. It has obtained invention certificates granted by countries such as China, the United States, Japan, and Israel, and offers both explosion-proof and standard product types.

The RMVC series high-voltage variable frequency speed control devices utilize sensorless vector control technology, which imposes no special requirements on the motor and is suitable for variable speed operation of medium and high voltage AC motors. The system offers both air cooling and water cooling options to meet different site requirements. The equipment has been tested and certified by TUV and is exported to 35 countries and regions worldwide.

The high-power water-cooled frequency converter product equipment adopts a modular assembly design for the power unit. The power unit uses a water cooling method, which offers high power density and is convenient for maintenance and installation.
