Products information
The 3-phase input-output inverter SJZO ZQ513M-315G3B-B is often used in industry such as rolling mills, mixers, centrifuges, etc. because the inverter can easily change speed or reverse motor rotation, reducing starting current when compared to the direct starting method, so it does not cause voltage drop or difficulty starting the device. In addition, starting the device through a low-speed inverter helps large-load motors not to start suddenly, helping to limit damage to mechanical parts, bearings and increase motor life. The inverter creates a stable, safe system through the electronic system of overcurrent, overvoltage and low voltage protection, creating a safe system for the operation of the motor.
3-phase inverter has the function of receiving 3-phase voltage with fixed frequency and through the inverter, this voltage is adjusted to 3-phase voltage with suitable frequency to run the motor, control the motor speed. The inverter includes a rectifier circuit that converts AC input power to DC, a flat capacitor, an inverter circuit, a control circuit, an AC reactor, a braking resistor, a communication module, etc. Basically, 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.
