Details of Inverter Model : SG-VB-4T030G/037P/30kW/40HP/3 phase 380VAC

Inverter Model : SG-VB-4T030G/037P/30kW/40HP/3 phase 380VAC is a three-phase inverter for 380/440VAC (Inverter Three Phase 380VAC). It converts direct current (DC) to alternating current (AC) of three phases, 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 of Inverter Model : SG-VB-4T030G/037P/30kW/40HP/3 phase 380VAC

• DC Input Power Supply:
• It may come from a battery, solar panel, or converted from household AC power to DC via Rectifier circuit.
• Switching Circuit (IGBT, MOSFET):
• Uses switching devices to rapidly switch the supply of electricity, generating alternating current signals.
• Controlled in a sequence of three phases (R-S-T or U-V-W).
• Waveform Control (PWM - Pulse Width Modulation):
• Uses PWM technique to create an output signal with a waveform as close to sine wave as possible.
• Can control the speed of AC motors based on 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 motor speed control and more energy-efficient than traditional on-off systems.
• Reduces starting surge currents for motors.
• Suitable for high torque loads. Applications of three-phase inverters, such as water pumps, fans, conveyor belts, and industrial machinery.
• HVAC systems (heating and cooling in buildings).
• Advantages of using Inverter Three Phase include energy savings.

• Extend motor lifespan
• Achieve more precise system control
• Reduce wear and tear from traditional motor starts
