Features: This is a single-phase 220V voltage input frequency converter designed to drive a three-phase motor by converting the connection to a T-ring type. Equipped with a 4-digit digital tube display for clear data visibility. Supports display of radiator temperature, output current, DC main voltage, engine speed, and operating frequency. Outputs 1.0–99.0Hz to improve output voltage performance. Utilizes SVPWM modulation mode with a carrier frequency of 8.0kHz. The frequency inverter allows adjustable V/F curve compensation for frequency and voltage ratio, enabling flexible control. Adjust the maximum V/F curve value according to load conditions to optimize energy efficiency, reduce motor heat, and extend the lifespan of both motor and inverter. Color: Black Material: ABS Package Contents: 1 x Frequency Converter Note: Other items not included. Note: Lighting and display differences may cause slight color variations between the image and actual item. Measurement error allowed is +/- 1–3 cm.
