This is a single-phase 220V voltage input frequency converter for driving a three-phase motor (ensure conversion to a Delta connection type). It features a four-digit digital tube display and an output range of 1.0-99.0Hz. To enhance output, this product utilizes SVPWM modulation mode with a carrier frequency of 8.0KHz. Suitable for motors under 750W, with a maximum output power of 1100W. Features: This is a 220V single-phase voltage input frequency converter for driving a three-phase motor (ensure conversion to a Delta connection type). Features a four-digit digital tube display for clear data viewing. Supports displaying heatsink temperature, current value, DC bus voltage, motor speed, and operating frequency. Output range of 1.0-99.0Hz; uses SVPWM modulation mode with an 8.0KHz carrier frequency for improved output. The frequency converter can arbitrarily change the V/F curve by setting the V/F compensation frequency and voltage-to-frequency ratio. By setting the maximum V/F curve value according to the load situation, it maximizes electrical energy utilization efficiency, reduces motor heat, and extends the lifespan of the motor and frequency converter. Provides low-frequency high torque, single-phase 220V input, three-phase 220V output, saving energy and electricity. Includes overheat and overvoltage protection.
