Support display radiator temperature value, current current value, direct current master voltage value, motor speed, operating frequency value. The is a single-phase 220 V voltage input frequency converter to drives a three-phase motor (be sure to convert the connection method into a t-riangle type). Output 1.0-99.0Hz, in order to improve the output voltage, this product uses SVPWM modulation mode, carrier-frequency 8.0KHz. Four-digit digital tube display, you can see the data clearly. The frequency converter can arbitrarily change the V/F curve by setting the V/F compensation frequency and the voltage ratio at the frequency., Weight: 0.83996121822 pounds, Manufacturer: tiyao
