220v Single-phase Input Three-phase Output Motor Driver Frequency Converter With Four-digit DigitalFeatures: This is a single phase 220V voltage input frequency converter to drive a three-phase motor (be to convert the connection into a T-ring type). 4-digit digital tube display, you can see the data clearly. Support radiator's temperature value, current current value, DC main voltage value, engine speed, operating frequency value. Output 1.0-99.0Hz to improve output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz. The frequency inverter can change the curve arbitrarily by adjusting the compensation frequency and voltage ratio at the frequency. By adjusting the maximum value of the V/F curve according to the load situation to maximise the use efficiency of electrical energy, reduce engine heat, extend the life of the motor and the frequency converter. Color: black Material: ABS Package Contents: 1X frequency converter Only the above package content, other products are not included.
