Water Pump AC Variable Frequency Drive 3AC 380V 90KW ~ 132KW

 

The inverter transmits the changed signal, and after the microcomputer judges the calculation and compares with the set pressure, it sends a command to change the frequency to the controller. The controller changes the speed of the water pump motor and the number of enabled pumps by changing the frequency, and automatically adjusts the peak and valley water consumption. To ensure that the pressure of the water supply network is constant to meet the needs of users
