3-ph VFD Inverter 11KW/15HP

The SINEE EM730-011-3B is a high-reliability, general-purpose inverter designed for industrial automation and machinery. Engineered to drive three-phase AC asynchronous motors and, in non-standard versions, permanent magnet synchronous motors, this model offers advanced control technologies such as vector V/F (VVF) and speed sensorless vector control (SVC). It supports both speed and torque output modes for versatile industrial applications12.

Key Features:

• Motor Compatibility: Three-phase AC asynchronous motors (permanent magnet synchronous motors in non-standard versions)

• Power Range: 11 kW (EM730-011-3B)

• Input Voltage: Three-phase 340–460V AC, 50/60 Hz

• Output Voltage: Matches input supply voltage

• Control Modes: V/F (VVF), speed sensorless vector control (SVC)

• Output Modes: Speed and torque

• Protection: Short circuit, overcurrent, overvoltage, overload, overheating, phase loss, load loss, external protection, and more

• Communication: Modbus RTU, Wi-Fi, mobile app support

• Display: Pluggable LED keyboard with five-digit digital tube, four operation buttons, digital potentiometer, and status indicators

• Overload Capability: Up to 150% rated current for 60 seconds (typical for this series)

• Cooling Method: Forced air (typical for this series)

• Special Functions: Rewinding, unwinding, high-frequency output (up to 3000 Hz), high-speed pulse input (100 kHz)

• Protection Class: IP20/IP21

• Applications: Woodworking, food, packaging, cable, fan, and hydropower machinery

Applications:
Ideal for variable speed control of industrial motors in manufacturing, material handling, HVAC, and process automation.
