FS300 series AC drive, supports Sensorless Vector Control (SVC) and V/F control.

SVC provides a speed regulation range of 1:200 and a speed accuracy of 0.5%, delivering stable and precise motor control. It has strong overload capacity, withstanding 150% rated current for 60 seconds and 180% rated current for 1 second.

Designed specifically for water supply systems, it integrates multiple pump-specific functions including intelligent multi-pump full variable frequency mode, automatic master-slave switching and backup master, pump regular rotation, antifreeze function, water shortage protection, burst pipe detection, high/low pressure alarm, sleep and wake-up, and soft pipeline filling function, ensuring safe and reliable system operation.

It supports Modbus-RTU and CAN communication, has an IP54 protection grade, adopts forced air cooling, with rated efficiency ≥93% (≤7.5kW) and ≥95% (11~22kW). It is suitable for water supply systems or automated control systems in residential communities, commercial buildings, agriculture and factories.
