Function and purpose Converts singlephase 220V supply into threephase 220V output so threephase motors can operate where only singlephase power is available. Provides adjustable output frequency (0–99 Hz) for accurate motor speed control. Key benefits — why you need it Enables use of threephase equipment without changing building wiring or installing a threephase feed. Frequency control lets you match motor speed to the task, improving process control and reducing mechanical stress. Builtin safety protections (overvoltage and shortcircuit protection) improve reliability and protect connected motors and equipment. Performance and compatibility Power options: 750 W and 1100 W ratings to suit small to medium threephase motors. Input: singlephase 220 V. Output: threephase 220 V. Frequency range: 0–99 Hz for flexible motor speed adjustment. Designed for direct drive of threephase motors; compatible with common industrial and workshop motor types that accept 220 V threephase input. Usability and operation Userfriendly digital display for realtime monitoring and quick adjustments of operating parameters. Simple integration into existing singlephase installations—no need for complex rewiring or additional transformers. Reliable operation under varying electrical conditions due to comprehensive protection features. Typical applications Workshop and light manufacturing: run CNC routers, milling machines, grinders, and other threephase tools on a singlephase supply. Pumps and compressors: power water pumps, air compressors, and similar equipment at controlled speeds for improved efficiency. Material handling and conveyors: drive small conveyors, fans, or other threephase machinery in retail, agricultural, or lightindustrial settings. Safety and reliability Multiple protection functions including overvoltage and shortcircuit protection to reduce downtime and protect both the inverter and connected motors. Digital monitoring aids fault detection and simplifies troubleshooting. Technical summary Input: singlephase 220 V Output: threephase 220 V Power ratings: 750 W / 1100 W Frequency range: 0–99 Hz Protections: overvoltage, shortcircuit Interface: digital display for monitoring and adjustments This inverter provides a practical, reliable solution for running threephase motors from a singlephase 220 V supply while offering frequency control and essential safety protections.
