3-Phase VFD Inverter

The SINEE EM730-7R5-3B is a high-reliability, general-purpose inverter (Variable Frequency Drive, VFD) designed for industrial automation and machinery applications. This model is engineered to drive three-phase AC asynchronous motors and permanent magnet synchronous motors, supporting advanced control technologies such as vector V/F (VVF) and speed sensorless vector control (SVC). It offers both speed and torque output modes, making it highly versatile for a wide range of industrial uses.

Key features include robust protection functions, reliable operation at full load even at 50°C ambient temperature, and special functions for rewinding and unwinding. The EM730-7R5-3B supports high-frequency output up to 3000 Hz for driving high-speed motors and features a 100 kHz high-speed pulse input. It is equipped with a plug-in LED keyboard for easy parameter setting and monitoring, and supports Wi-Fi access and mobile app integration for remote debugging and monitoring. The inverter is suitable for applications such as woodworking, food processing, packaging, cable equipment, and fan hydropower.
