Modular design, front maintenance, no need to disassemble. Equipped with intelligent fault diagnosis, it can quickly locate problems. The cooling system is designed with a long lifespan, and the lifespan of the fan capacitor is extended. The maintenance cycle is twice as long as that of a regular frequency converter.
Supports asynchronous motors and permanent magnet synchronous motors. Permanent magnet motors have high efficiency and more precise control. It also supports three modes: V/F, open-loop vector, and closed-loop vector, with strong adaptability. You can choose any type of motor.
Water cooling design, quieter and more efficient than air cooling. The heat dissipation channel is isolated from internal components, making it less prone to dust accumulation and stable operation even in high temperature environments. 2800kW high-power operation does not cause overheating, and the equipment has a longer lifespan.
