Compared with the standard three-phase motor starter, STP-SCIII has advanced functions. It continuously monitors for anomalies that could shorten the life of the motor or cause downtime.

Continuous diagnosis

STP-SCIII will alert maintenance technicians to source problems, including empty running, extended running, overvoltage, undervoltage, relay failure, voltage/current imbalance, rotor locking, phase loss, or open circuit.

Automatic pump start

"On demand" automatic start pump, more than eight submersible pumps can be connected to the same discharge line. Variable frequency pumps begin to meet initial demand, and as demand increases, additional pumps are activated, thereby reducing power consumption and extending pump life.

Easy transformation

STP-SCIII is compatible with most existing 3 to 5 HP three-phase submersibles. Retrofitting an existing station is as easy as replacing an existing three-phase controller or starter with STP-SCIIII. No additional wiring required.
