The is a single-phase 220 V voltage input frequency converter to drives a three-phase motor (be sure to convert the connection method into a t-riangle type). 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. Suitable for motors below 750W, the maximum output power is 1100W. Features: The is a single-phase 220 V voltage input frequency converter to drives a three-phase motor (be sure to convert the connection method into a t-riangle type). Four-digit digital tube display, you can see the data clearly. Support display radiator temperature value, current current value, direct current master voltage value, motor speed, operating frequency value. Output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier-frequency 8.0KHz. The frequency converter can arbitrarily change the V or F curve by setting the V or F compensation frequency and the voltage ratio at the frequency. By setting the maximum value of V or F curve, according to the load situation, to maximize the use efficiency of electric energy, reduce the heat of the motor, prolong the servicelife of the motor and frequency converter. Low frequency high torque, 220 V single-phase input, 220 V three-phase output, energy saving and electricity saving. Overheating and over-voltage protections.
