PW Intelligent Controller – 380V Single Pump
Multifunction intelligent pump controller for automatic control and full electrical protection
of direct-start three-phase pumps from 0.75kW to 15kW.
Designed for single-pump booster, borehole and irrigation applications.
What this controller is designed for
This PW Intelligent Controller is designed to control and protect
a single three-phase (380V) pump.
It automatically starts and stops the pump based on demand or level
and provides advanced protection against electrical and hydraulic faults.
