1. This is a single-phase 220V input frequency converter for controlling three-phase motors. Be sure to convert the connection method to T-shaped triangle type. 2. Four-digit digital tube display, output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz. 3. Suitable for motors less than 750W, the maximum output power is 1100W. 4. This is a single-phase 220V input frequency converter for controlling three-phase motors. Be sure to convert the connection method to T-shaped triangle type. Four-digit digital tube display, you can see the data clearly. Support the display radiator temperature value, current value, DC main voltage value, motor speed, working frequency value. 5. Output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz. 6. The frequency converter can arbitrarily change the V/F curve by setting the V/F compensation frequency and the voltage-frequency ratio. Setting the maximum value of the V/F curve according to the load situation, to maximize the efficiency of electrical energy utilization, reduce motor heat, extend the service life of the motor and frequency converter. 7. Low frequency high torque, single-phase 220V input, three-phase 220V output. 8. Overheating and overvoltage protection. 9.
