The VARIOspeed® variable frequency drive (VFD) is designed for constant pressure control applications, including booster pumps, deep well submersible pumps, and irrigation pumps.
As flow and head conditions change in the pumping system, the VARIOspeed® VFD is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is set on the VFD keypad. The pressure transducer measures the pump discharge pressure.
The CSCPC4 Controller is specifically designed for constant pressure applications using 1-4 variable frequency drives (VFDs). It features P.I.D. control, automatic alternation, data logging, and communication capabilities. The backlit graphic display allows the user to monitor pressure, pump speeds, and alarm status. The menu driven setup makes navigation and configuration fast and simple.
