3-Phase 380V 280KW Sinusoidal output filter

  Sinusoidal output filter: Output voltage in sine waves. Safeguard the motor cable and enable multiple motor connections. Use inverter and UPS AC/DC equipment to produce a sine wave and purify the equipment. No maximum length for the output cable. A type of special inverter known as a motor frequency inverter drives special frequency asynchronous motors at very near ranges (motor cable less than 100 meters). It typically operates in the SPWM modulation mode. Over 100 meters of motor cable can result in excessive du/dt, which can harm the motor's insulation, age the coils, increase core loss, and still further cause bearing heating, damage to the motor, or even burn the motor in extreme circumstances. To remedy this issue, the user must select a sine wave filter.
