Features: This is a single-phase 220V input frequency converter designed to drive a three-phase motor (ensure the motor is connected in a delta configuration). 4-digit LED display for clear visibility of operating data. Displays heatsink temperature, output current, DC bus voltage, motor speed, and operating frequency. Output frequency range: 1.0–99.0 Hz with improved voltage output; uses SVPWM modulation with a carrier frequency of 8.0 kHz. Adjustable U/F curve via U/F compensation settings for frequency and voltage ratio. Optimize the V/F curve maximum value based on load conditions to improve energy efficiency, reduce motor heat, and extend motor and inverter lifespan. Color: Black Material: ABS Package Includes: 1 × Frequency Converter Note: Due to lighting conditions and screen variations, the actual product color may differ slightly from images. Measurement tolerance: ±1–3 cm.
