VARIOspeed® N1 Control Panel

The VARIOspeed® N1 control panel controls a three phase pump in constant pressure control applications.

 

The VARIOspeed® N1 control panel is designed to control a three phase pump in constant pressure control applications, including booster pump, deep well submersible pump, and irrigation pump applications.

 

It features a variable frequency drive and display in a NEMA 1 enclosure. As flow and head conditions change in the pumping systems, the VFD is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is entered on the display inside the control panel. The pressure transducer measures the pump discharge pressure.

 

Not for use with sewage pumps.
