A single-phase 220V input frequency converter designed to drive a three-phase motor (must be connected in a delta configuration). Features a four-digit digital display for clear viewing of operating data. Supports display of radiator temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0Hz. Utilizes SVPWM modulation with an 8.0kHz carrier frequency to improve output voltage quality. Adjustable V/F curve via settings for V/F compensation frequency and voltage ratio, allowing optimization based on load conditions to enhance energy efficiency, reduce motor heat, and extend the service life of both motor and converter. Delivers high torque at low frequencies. Converts single-phase 220V input to three-phase 220V output for energy-efficient operation. Includes protection against overheating and over-voltage.
