Features Inverter (Inverter) Model : SG-VB-4TR75GB/0.75kW/1HP/3 phase 380VAC

DC Input Power:

• It may come from a battery, solar panel, or converted from household AC power to DC through a Rectifier circuit.

Switching Circuit (IGBT, MOSFET):

• Uses switching devices to rapidly switch power supply, generating alternating current signals.
• Controlled to switch in a three-phase sequence (R-S-T or U-V-W).

Waveform Control (PWM - Pulse Width Modulation):

• Uses PWM technique to create output signals with waveforms closest to sine waves.
• Can control the speed of AC motors from the frequency of PWM.

Output Result Three-phase alternating current that can be used with various loads such as three-phase motors. Advantages of using a three-phase inverter Precise speed control of AC motors, more energy-efficient than traditional on-off systems.

Reduces motor starting surge currents

• Suitable for high torque loads. Applications of three-phase inverters Three-phase motor systems such as water pumps, fans, conveyor belts.
• Industrial machinery
