This is a single-phase 220 V voltage input frequency converter designed to drive a three-phase motor (please ensure the connection method is converted to a triangle type). It features a four-digit digital tube display for clear data visibility. Supports display of radiator temperature, current value, DC voltage value, motor speed, and operating frequency. Output range 1.0-99.0Hz. This product uses SVPWM modulation mode with a carrier frequency of 8.0KHz. The frequency converter allows adjustment of the V/F curve by setting the V/F compensation frequency and the voltage ratio. By setting the maximum value of the V/F curve according to the load situation, it helps reduce motor heat and prolong the service life of the motor and frequency converter. Features low frequency high torque. 220 V single-phase input, 220 V three-phase output. Includes overheating and over-voltage protections.
