KY900E Series High Power Air Compressor Dedicated Variable Frequency Drive

High Power Air Compressor Dedicated Variable Frequency Drive is a variable frequency control device designed for large industrial air compressors. It achieves high efficiency, energy saving, precise gas supply, and equipment protection by adjusting the motor speed.

• The power range covers 15kW to several hundred kilowatts, suitable for large air compressors such as screw and centrifugal compressors.
• Support parallel drive of multiple motors to meet the requirements of complex industrial scenarios.

• Using space vector pulse width modulation (SVPWM) or direct torque control (DTC) technology, dynamically adjust the motor speed to match the actual gas demand.
• The energy-saving effect is significant, and compared with traditional power frequency drive, it can reduce energy consumption by 30% -50%.

• Built in pressure closed-loop control system, with real-time feedback from pressure sensors, automatically adjusts motor speed, and maintains a constant gas supply pressure (error ≤± 0.01MPa).
• Supporting PID regulation, it can achieve fast response and stable control.

• Integrate multiple protection mechanisms such as overload, overvoltage, undervoltage, overcurrent, overheating, and grounding faults to extend equipment lifespan.
• Support motor soft start/soft stop to reduce mechanical impact.

• Supports industrial communication protocols such as Modbus, Profibus, EtherCAT, etc., making it easy to integrate with upper computers or PLCs.
• Provide remote monitoring and fault diagnosis functions to reduce maintenance costs.

• Support power module expansion and flexible configuration according to needs.

• Gas supply systems for large-scale pneumatic equipment in industries such as steel, chemical, and power.
• Pneumatic tools and ventilation systems in mining, tunnel and other engineering projects.

• Gas supply for automated production lines in industries such as automobile manufacturing and mechanical processing.
• Gas supply for precision equipment in industries such as electronics and textiles.

• High pressure gas delivery systems such as natural gas refueling stations and LNG factories.
• Auxiliary gas supply for wind power generation, hydropower stations and other equipment.
