Application scenarios

Industrial automation: Used for controlling three-phase motors, it is widely applied in manufacturing, processing plants and production line equipment, such as conveyor belts, compressors, fans and pumps.

Pump control: The pump start and stop modes are particularly suitable for water treatment, irrigation systems and the chemical industry, reducing water hammer effects and pipeline pressure shocks.

Heavy-duty equipment: Suitable for heavy machinery that requires high power output, such as crushers, mixers and heavy conveying systems, especially in the mining, metallurgy and cement industries.

Energy conservation and equipment protection: Through soft start and intelligent braking functions, the peak current and mechanical wear during motor start-up are reduced, extending the equipment's lifespan. It is suitable for energy-sensitive applications.

Complex control requirements: Multiple start-up modes and protection functions make it suitable for scenarios that require precise control and reliability, such as HVAC systems, elevators, and lifting equipment.
