VFDC-4100 Controller

1 - 4 Pump Control Applications

The VFDC-4000 Controller maintains a constant discharge pressure by adjusting the speed of 1 to 4 VFDs in pressure booster pump systems.

The VFDC-4100 is a microprocessor based controller specifically designed for constant pressure applications using 1-4 variable frequency drives.  It features P.I.D. control, automatic alternation, data logging, and communication capabilities.  A backlit graphic display allows users to monitor pressure, pump speed and alarm status.  The VFDC-4100 controller uses a menu driven setup that makes navigation and configuration fast and simple.
