frequency ac drive for Water Pump

Characteristics 1. Input & Output Characteristics of frequency ac drive: Rated output capacity: 0.4KW up to 2.2KW, rated voltage: 220V, 380V 1. Control Method: Closed-loop System with PID inside: Frequency inverterControl the motor of water pump by pressure sensor. Prevent the water level from large fluctuation by maintaining constant pressure. 2. Protective Function: Protect the motor and water pump from over voltage, over current. When the water level is much lower than the normal one, the water pump will stop automatically. When the power supply is normal again after power failure, the water pump will work again automatically. 3. Easy to operate: The controller can be installed and used conveniently. 4. Energy Saving Function: When the user doesnt use water, the motor and water pump can stop automatically. ApplicationsMain application of frequency ac drive : All of possible areas that need water supply of constant pressure such as household, hotel, school, Sauna Room, farm and factory, etc.
