This is a single-phase 220V voltage input frequency converter for driving a three-phase motor (be sure to convert the connection method to delta type). Four-digit digital tube display, output 1.0-99.0 Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0 KHz. Suitable for motors less than 750W, the maximum output power is 1100W. Features: This is a frequency converter 220V single-phase voltage input to drive three-phase motor (be sure to convert the connection method to a T-triangle type). Four-digit digital tube display , you can see the data clearly. Supports displaying radiator temperature value, current current value, DC main voltage value, motor speed, frequency value of operation. Output 1.0-99.0 Hz, in order to improve the 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 the voltage-to-frequency ratio. By setting the maximum value of the V/F curve , depending on the load situation, to maximize the use efficiency of electric energy, reduce motor heat, extend the life of motor and frequency converter. Low frequency high torque, single-phase 220V input, three-phase 220V output, energy saving and electricity saving. Overheating and overvoltage protections.
