Problems it solves
Why this model gets specified
One site needs constant pressure, the next needs plain speed control. FS300 runs both modes and switches between them.
PM pump motors are more efficient but need matched control. The integrated PM-and-asynchronous design drives either.
Pressure control loops that need tuning slow commissioning. A built-in dedicated PID algorithm handles constant-pressure supply out of the box.
Who it is for: Pump manufacturers and water-supply contractors covering both 220 V small sets and 380 V systems up to 22 kW.
