Product Applications

Water supply and sewage treatment: Utilizing its proprietary pump control mode, it can smoothly control the start and stop of centrifugal pumps, protecting the pipeline system from damage caused by pressure fluctuations.
Mining and heavy industry: Applicable to conveyor belts, crushers, mills, and centrifuges and other equipment that require high starting torque and are sensitive to mechanical wear.
Steel and metallurgy: Used in aluminum smelting, hot/ cold rolling production lines, and iron/steel smelting processes, for controlling large ventilation fans and heavy drive devices.
Heating, ventilation, and air conditioning (HVAC): Used to drive large cooling tower fans and water chillers' compressors, improving energy efficiency by optimizing motor operation.
Compressors and pneumatic systems: Significantly reduces the current peak during the startup of air compressors, protecting grid stability and extending motor lifespan.

Core parameters and features
Rated capacity: Rated current is 970 A, suitable for motors with a power of up to 800 HP at a 460V AC voltage.
Control voltage: Input control voltage range is 100...120V AC.
Structural design: Open (Open) structure with built-in bypass (Internal Bypass) function, which can effectively reduce heat generation during operation.
Control mode: Supports 17 startup and stop modes, including pump control (Pump Control) option, which can effectively eliminate "water hammer effect".
