VARIOspeed® 3R Duplex Control Panel
Variable Frequency Drive Controller in a NEMA 3R Enclosure for Indoor or Outdoor Use
The VARIOspeed® 3R control panel is designed to control (2) three phase pumps in constant pressure control applications including booster pump, deep well submersible pump, and irrigation pump applications.
As flow and head conditions change in the pumping system, the VFDs are able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is entered on the display inside the panel. The pressure transducer measures the pump discharge pressure.
Not for use with sewage pumps.
