Pure Sine Wave Inverter Board Sinusoidal DC Inverter Driver EGS002 Inverter Board Uses EG8010 IR2110S Chip
Product Description
EGS002 is a driver board specific for single phase sinusoid inverter. It uses ASIC EG8010 as control chip and IR2110S as driver chip. The driver board integrates functions of voltage, current and temperature protection, LED warning indication and fan control.Jumper configures 50/60Hz AC output, soft start mode and dead time. EGS002 is an improved version of EGS001 that is compatible of EGS001’s original interfaces. EGS002 also integratescross-conduction prevention logic to enhance its ability of anti-interference, and LCD display interface for users’ convenience to use chip’s built-in display function.
EG8010 is a digital pure sine wave inverter ASIC (Application Specific Integrated Circuit) with complete function of built-in dead time control. It applies to DC-DC-AC two stage power converter system or DC-AC single stage low power frequency transformer system for boosting. EG8010 can achieve 50/60Hz pure sine wave with high accuracy, low harmonic and distortion by external 12MHz crystal oscillator. EG8010 is a CMOS IC that integrates SPWM sinusoid generator, dead time control circuit, range divider，soft start circuit, circuit protection, RS232 serial communication, 12832 serial LCD unit, and etc

Note
LCD Type: 1. Special LCD; 2. Ordinary 128*32 LCD, (LCD needs to be purchased separately) without wiring. This driver board has: A: Under-voltage protection+128*32 LCD B: Under-voltage protection + special LCD A and B use the same function. If you want to use the screen, you have to look carefully. Different screens need to use different programs. (This LCD screen does not have a blue backlight) Q: The display does not light up If the display can not be displayed, first test with 1 pin and 2 pins with 5V to see if it is normal. Pay attention to the connection method, you need to have a driver, and it will light up when there is a signal.
