Applications:

• In order to mitigate mechanical degradation and prevent water hammer, pumps and fans are implemented in HVAC and water treatment systems.
• Compressors are utilized in manufacturing to minimize voltage fluctuations through controlled starts.
• Reliable torque management is achieved through the use of industrial machinery and conveyors in automation lines.
• Onboard compressors and marine propulsion auxiliaries for vibration-sensitive operations.
• In factories, the control of general three-phase AC motors necessitates gentle starting for currents of up to 250A.
