Features: This is a single phase 220V voltage input frequency converter designed to drive a three-phase motor by converting the connection into a T-ring type. Equipped with a 4-digit digital tube display for clear data reading. Supports display of radiator temperature, output current, DC main voltage, engine speed, and operating frequency. Output frequency range: 1.0-99.0Hz. Enhances output voltage using SVPWM modulation mode with a carrier frequency of 8.0KHz. The frequency inverter allows adjustment of the V/F curve by modifying compensation frequency and voltage ratio, enabling flexible control. Optimize energy efficiency by adjusting the maximum V/F curve value according to load conditions, reducing motor heat and extending the lifespan of both motor and inverter. Color: Black Material: ABS Package Contents: 1 x Frequency Converter Note: The package includes only the items listed above. Other accessories are not included. Lighting reflections and differences in display screens may cause slight variations between the color shown in the image and the actual product. Measurement error allowed is +/- 1-3 cm.
