AC Motor Drive
Applications
- Pump is mainly applied in the air condition, wastewater treatment, heating system and pressurized device.
- PUMP takes 20% of global power consumption.
- Pump system driven by converter can save 30~50% of energy.

Features
- The traditional pump employs the commercial power (constant frequency)to drive the motor, and uses the throttle to adjust the required output flow rate or pressure. This method causes the waste of electric energy.
- The pump with inverter can change input power frequency for ACmotor, and simultaneously adjust the revolution speed of motor to substitute the throttle to adjust the required output flow rate or pressure.
