Details of Inverter (Inverter) Model : SG-VB-4T5R5GB/7R5PB/5.5kW/7.5HP/3 phase 380VAC

Inverter (Inverter) Model : SG-VB-4T5R5GB/7R5PB/5.5kW/7.5HP/3 phase 380VAC Three Phase Inverter 380/440VAC is a device that converts direct current (DC) to three-phase alternating current (AC), with an output voltage of approximately 380 volts, which matches the standard industrial electrical system in Thailand. SCMA distributes Brands SANGI. The working principle of a three-phase inverter.

Features Inverter (Inverter) Model : SG-VB-4T5R5GB/7R5PB/5.5kW/7.5HP/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, creating 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, accurate motor speed control and more energy-efficient than traditional on-off systems. Reduced starting surge currents for motors. Suitable for high torque applications. Used in three-phase motor systems such as water pumps, fans, conveyor belts, and industrial machinery.
