Pure Sine Wave Inverter Driver Board EGS002 LCD Display

Pure Sine Wave Inverter Driver Board EGS002 LCD Display is a comprehensive, high-performance driver module designed for single-phase pure sine wave inverter systems. This board utilizes the EG8010 digital generator chip as its core and couples it with the IR2110S high-voltage half-bridge driver to provide a complete SPWM (Sinusoidal Pulse Width Modulation) control solution. Consequently, it enables users to build reliable, high-efficiency power inverters with minimal external circuitry. The module also features a dedicated interface for the included LCD display, which provides real-time monitoring of critical parameters like voltage, current, and temperature. Furthermore, its robust protection logic ensures the safety of both the inverter and the connected load. Therefore, the EGS002 remains the top choice for DIY enthusiasts and industrial engineers seeking a stable 50/60Hz AC power source.

Key Features:

• Pure Sine Wave Output: The module generates a high-precision pure sine wave signal, ensuring compatibility with sensitive medical and laboratory equipment.
• Integrated Protection Logic: It offers built-in protection against overvoltage, undervoltage, overcurrent, and overheating to prevent system failure.
• Adjustable Frequency: Users can easily select between fixed 50Hz and 60Hz frequencies or use the variable 0−400Hz mode via jumper settings.
• LCD Real-Time Display: The included 12832 LCD screen displays essential data, allowing for immediate diagnostics and performance tracking.
• Dead-Time Control: Four adjustable dead-time settings (300ns, 500ns, 1.0us, and 1.5us) help prevent “shoot-through” in the power MOSFET stage.
