This is a single-phase 220V voltage input frequency converter to a three-phase motor (be sure to convert the connection method to a T-type). Digital four-digit tube display, output 1.0-99.0 Hz, to improve the output voltage, this product uses the SVPWM modulation mode, frequency frequency 8.0 kHz. Suitable for motors under 750 W, the maximum output power is 1,100 W. Features: This is a 220 V single-phase voltage input frequency converter to a three-phase motor (be sure to convert the connection method to a t-triangle type). Data. Handling display of radiator temperature value, the value of the current current, the value of the main continuous current voltage, the motor speed, the value of the operating frequency. Output 1.0-99.0 Hz, to improve the output voltage, this product uses the SVPWM modulation mode, frequency frequency 8.0 kHz. The frequency converter can arbitrarily modify the V/F curve by defining the V/F compensation frequency and frequency voltage ratio. By defining the maximum value of the V/F curve, as a function of the load situation, to maximize the efficiency of electrical energy, reduce motor heat, extend the life of the motor and frequency converter. Single-phase 220 V, 220 V three-phase output, energy saving and electricity saving. Overheating and overvoltage protection.
