SMART CONTROL FOR HIGH CAPACITY PUMPS

STP-SCIII delivers advanced features compared to standard three-phase motor starters. It constantly monitors for abnormal conditions that could reduce motor life or cause downtime.


Continuous Diagnostics

The STP-SCIII will alert the service technician to the source problems including dry run, extended run, overvoltage, undervoltage, relay fault, voltage/current unbalance, locked rotor, phase loss or open circuit.

Pump Auto-Start

Get “on demand” automatic pump start of up to eight submersible pumps manifolded to the same discharge line. The lead pump starts to satisfy initial demand and additional pumps are started as demand increases, reducing power consumption and extending pump life.

Easy Retrofit

The STP-SCIII is compatible with most existing three-phase submersibles from 3 to 5 hp. Retrofitting existing stations is as simple as replacing the existing three-phase controller or starter with the STP-SCIIII. No additional wiring is required.
