SJE-Rhombus 1030984, VS21-10.0-N3R, VARIOspeed Series, Variable Frequency Drive (VFD) Control Panel, 240 Volts, 1 Phase, 10.0 Amps, Indoor/Outdoor NEMA 3R Enclosure

FEATURES

SJE Rhombus VARIOspeed 3R Indoor/Outdoor VFD Controller

The VARIOspeed 3R 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 display inside the control panel. The pressure transducer measures the pump discharge pressure. 

This controller can be used in applications where three phase power is not available. The drive will convert 240V, single phase power into 240V, three phase power. A three phase motor must be used in all cases.

Note: This control panel is NOT for use with sewage pumps.
