Description of this 75kw 90 kw 380V Powtech speed controller PID control for constant pressure water supply

Powtech PID control for constant pressure water supply

 
Feature of this 75kw 90 kw 380V Powtech speed controller PID control for constant pressure water supply

Powtech inverter PT300 series are built-in PID regulator, pressure sensor real-time detection manager and translated into analog signals (0 to 10 v or 0 to 20 ma), directly into the inverter analog input port, the set pressure value, given the PID parameter values, the output frequency of the transducer after the built-in PID arithmetic control. System parameters can be adjusted in actual operation, lead to the complete control system response. When the water consumption is little or no water, water pump conditions, has been in a low speed inverter automatic open intelligent dormancy function, water pump stop, when water consumption increase, pressure is not enough, the inverter automatically awakening, the pump running, which greatly increase the pump service life and save power more effectively.
