Product Overview
The SUSWE SU300-2R2G2-2 is a compact, high-performance Variable Frequency Drive (VFD) designed to run 3-phase 220V electric motors from a standard domestic single-phase 220V power supply. Featuring advanced V/F and vector control modes, it provides smooth speed adjustment, stable low-frequency torque, and energy-efficient operation for workshop machinery, lathes, milling machines, pumps, and CNC spindles.
Item Condition & Packaging Notice:
Condition: Brand New (Other)
Packaging Details: This unit is 100% brand new and unused. It arrived at our warehouse without its original factory retail box and without a printed instruction manual.
