VFDC-3000
Controller for Constant Pressure Applications
The VFDC-3000 controller is designed to operate up to 3 pumps in a constant pressure application. The controller automatically adjusts pump speed and the on and off pump sequence in response to changes in the system pressure. When used to control the system pressure, a 4-20mA pressure transmitter is connected to the input. The controller features a rotary selector knob in addition to left shift and escape push buttons for intuitive menu navigation and quick setting adjustments.
