SJE-Rhombus introduces the SubCon variable-frequency drive. The SubCon VFD provides an energy-efficient solution for residential water well pump control. Water pressure is monitored continuously, and this variable-frequency drive will automatically adjust the pump speed to maintain a constant pressure. The set pressure, along with other parameters, is adjusted via the keypad. The display features current pressure in PSI, target pressure setting, pump speed (Hz), pump amps, pump run time and error codes. The SubCon VFD is available for 1.5-HP and 3-HP 230V applications, and is supplied in a NEMA 1 enclosure.
