SINEE EM730-022-3B - Frequency Drive 22 kW 380 VAC

The Sinee EM730-022-3B Frequency Drive is a reliable 22kW (30HP) Variable Frequency Drive (VFD) designed for precise motor speed control in demanding industrial applications. Whether you're operating woodworking machinery, food processing lines, packaging equipment, cable production, or fan systems, this high-power VSD (Variable Speed Drive) delivers smooth performance, energy savings, and long-term dependability.

Engineered with advanced control technology, the EM730 series VFD inverter supports both AC asynchronous and permanent magnet synchronous motors. It offers multiple drive control modes including vector VF and sensorless vector control (SVC), making it a versatile and powerful solution for modern motor control requirements. Built to perform in tough environments, it features strong vibration resistance, high-temperature tolerance, and flexible integration with mobile apps, Wi-Fi modules, and standard control systems.
