A single-phase 220 V voltage input frequency converter designed to drive a three-phase motor (must be connected in a delta configuration). Features a four-digit digital tube display for clear reading of data. Supports display of radiator temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0 Hz. Utilizes SVPWM modulation with a carrier frequency of 8.0 kHz to improve output voltage efficiency. Adjustable V/F curve settings allow customization of V/F compensation frequency and voltage ratio, enabling optimized energy usage based on load conditions. This helps reduce motor heat, improve energy efficiency, and extend the service life of both the motor and frequency converter. Provides low-frequency high-torque performance. Input: 220 V single-phase; Output: 220 V three-phase. Includes protection against overheating and overvoltage.
