380V 350kw 3-phase input 3-output inverter - 476HP SJZO ZQ513M-350G3B-B

The SJZO ZQ513M-350G3B-B 3-phase input-output inverter consists of a rectifier circuit that converts AC input to DC, a flat capacitor, an inverter circuit, a control circuit, an AC reactor, a braking resistor, a communication module, etc. These components help the inverter perform the function of receiving 3-phase voltage at a fixed frequency and adjusting it to 3-phase voltage at a suitable frequency to control the motor speed. :The operation of the inverter is to change the power parameters to adjust the motor speed, creating new mechanical characteristics to achieve a more productive working speed.

Starting the device through the inverter from low speed helps large load motors not to start suddenly, helping to limit damage to mechanical parts, bearings and increase motor life. 3-phase inverters are often used in industry such as rolling mills, mixers, centrifuges, etc. because the inverter can easily change the speed or reverse the rotation direction of the motor, reducing the starting current when compared to the direct starting method, so it does not cause voltage drops or difficulty starting the device. The inverter creates a stable, safe system through the electronic system that protects against overcurrent, overvoltage and low voltage, creating a safe system for the operation of the motor.
