The Guardian Series™ single-phase controller takes a major leap forward in fixed speed Submersible Turbine Pump (STP) control. Built upon the solid FE PETRO® brand smart controller platform, Guardian Series™ controllers feature an enhanced user interface, greater functionality, and higher performance compared to standard control boxes.

Effective immediately, the STP-SCI is no longer available. The new SPGC-220 Guardian Series™  single-phase controller is a direct replacement for the STP-SCI  – retaining the same fit, form, and function of the STP-SCI with additional new features. Replacement parts for the STP-SCI will  remain available until further notice.
