Features: It is a single-phase 220V voltage input inverter to drive a three-phase motor (be sure to convert the wiring method to T-delta type). Four-digit digital tube display, data is clearly visible. Support display radiator temperature value, current current value, DC main voltage value, motor speed, running frequency value. Output 1.0-99.0Hz. To increase the output voltage, this product adopts SVPWM modulation with a carrier frequency of 8.0KHz. The inverter can change the V/F curve arbitrarily by setting the V/F compensation frequency and the voltage ratio at that frequency. By setting the maximum value of the V/F curve, it maximizes the efficiency of power utilization, reduces the heat of the motor, and extends the service life of the motor and inverter according to the load. Low frequency and high torque, 220V single-phase input, 220V three-phase output, energy saving and power saving. Overheat and overvoltage protection.
