Single-phase 220V input frequency converter designed to drive three-phase motors (motor connection must be configured in delta type). Features a four-digit digital display for clear visibility of operating parameters including radiator temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0Hz. Utilizes SVPWM modulation with 8.0kHz carrier frequency to enhance output voltage quality. Supports adjustable V/F curve settings, allowing optimization of energy efficiency, reduced motor heating, and extended equipment lifespan. Delivers high torque at low frequencies. Input: single-phase 220V AC; output: three-phase 220V AC. Built-in protections include overheat and overvoltage protection. Suitable for motors up to 750W; maximum output power 1100W.
