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.<br> Support radiator's temperature value, current current value, DC main voltage value, engine speed, operating frequency value.<br> Output 1.0-99.0Hz to improve output voltage, this product uses SVPWM modulation mode, carrier frequency 8.0KHz.<br> The frequency inverter can change the curve arbitrarily by adjusting the compensation frequency and voltage ratio at the frequency.<br> 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.<br> Color: black<br> Material: ABS<br> Package Contents:<br> 1X frequency converter<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
