GUARDIAN SERIES™
FIXED SPEED PUMP
CONTROLLER
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.
SPECIFICATIONS
HIGHLIGHTS
• Compatible with FE PETRO® single-phase 2 Hp, 1½ Hp,
⅓ Hp, and ¾ Hp fixed speed STPs, as well as comparable
competitive STPs.
• 3½" digit LCD provides readable running and fault status
for quick troubleshooting.
• Separate “Reset” and “Silence/Calibrate” push buttons
