High Performance High Torque Frequency Converter

High Performance High Torque Frequency Converter

Single-phase/three-phase 220V-240V 0.4kW-2.2kW
Three-phase AC  340V-460V 0.75kW-450kW

The EM730 series inverter is a high-reliability general-purpose inverter launched by SINEE. EM730 supports three-phase AC asynchronous motors and permanent magnet synchronous motors. They support a variety of drive control technologies, such as the vector VF (VVF) control and speed sensorless vector control (SVC); speed output and torque output; and Wi-Fi access and background 

Features of the EM730 series inverter:
1.Support the mobile APP and Wi-Fi module to facilitate inverter debugging and monitoring
2.Reliable operation with full load at 50°C ambient temperature
3.Integration of special functions for rewinding and unwinding
4.Support the high-frequency output up to 3000Hz for driving high-speed motors
5.Support the 100kHz high-speed pulse input
6.Metal substrate should adapt to the vibratory environment to reduce the induced voltage of the motor.
7.Built-in filter is close to Level C3.
