This is a single-phase 220V voltage input frequency converter for driving a three-phase motor (ensure conversion of connection method to a delta connection type). Four-digit digital tube display, output 1.0-99.0 Hz, to improve output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0 kHz. Suitable for motors under 750W, the maximum output power is 1100W. Features: This is a single-phase 220V voltage input frequency converter for driving a three-phase motor (ensure conversion of connection method to a delta connection type). Four-digit digital tube display, you can see data clearly. Supports displaying cooling fan temperature value, current current value, DC voltage value, motor speed, operating frequency value. Output 1.0-99.0 Hz, to improve output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0 kHz. The frequency converter can arbitrarily change the V/F curve by setting the V/F compensation frequency and voltage ratio at the frequency. By setting the maximum value of the V/F curve, depending on the load situation, to maximize the utilization efficiency of electrical energy, reduce motor heat, extend the life of the motor and frequency converter. Low frequency high torque, 220V single-phase input, 220V three-phase output, energy saving and electricity saving. Overheating and overvoltage protection.
