FEATURES
SJE Rhombus VARIOspeed N1 Indoor VFD Controller
The VARIOspeed N1 is a Variable Frequency Drive (VFD) control panel designed to control a three phase pump in 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 VFD is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is entered on the door mounted display. The pressure transducer measures the pump discharge pressure.
Note: This control panel is NOT for use with sewage pumps.
