220V Single-phase Input Three-phase Output Motor Driver Frequency Converter with Four-digit Digital Display Features: This is a single-phase 220V voltage input frequency converter designed to drive a three-phase motor. Equipped with a 4-digit digital tube display for clear data reading. Supports monitoring of radiator temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0Hz. The product uses SVPWM modulation mode with a carrier frequency of 8.0kHz to improve output voltage quality. The frequency inverter allows adjustment of the V/F curve by setting compensation values for frequency and voltage ratio, enabling flexible control performance. Adjust the maximum V/F curve value according to load conditions to optimize energy efficiency, reduce motor heat generation, and extend the service life of both motor and inverter.
