Variable Frequency Drive, 220V 750W Single Phase to Three Phase Motor Controller with Digital Display

This is a single-phase 220 V input frequency converter designed to drive a three-phase motor (motor connection must be configured in delta configuration). It features a four-digit LED display for clear visibility of operational data. The display shows heatsink temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0 Hz. The unit uses SVPWM modulation with an 8.0 kHz carrier frequency to enhance output voltage performance. The V/F curve is adjustable via user-defined settings for compensation frequency and voltage ratio at frequency. The maximum V/F curve value can be set according to load requirements to optimize energy efficiency, reduce motor heating, and extend the service life of both the motor and the frequency converter. Delivers high torque at low frequencies. Input: 220 V single-phase; Output: 220 V three-phase. Includes overheat and overvoltage protection.
