Product advantages
Low-Frequency Strong Start: Output 180% rated torque at 0.5 Hz low frequency; ensures smooth startup for heavy-load equipment.
Wide Voltage Adaptability: Supports 380V - 480V wide voltage input, adaptable to complex grid environments.
Strong Overload Tolerance: Heavy-duty models support 150% rated current for 60 seconds; effectively prevents unplanned shutdowns under high impact loads.
