User less batch stage, you can buy this drive board directly to produce inverter. After production, the user simply buy a EG8030 chip, we provide the driver board schematics, PCB board file, the user can produce their own driver board. EGS031 driver board, can be used as EG8030 evaluation board, can also be used for three-phase inverter, three-phase UPS, three-phase EPS mass production of the driver board. EGS031 is a three-phase pure sine wave inverter drive board using EG8030 as the core control chip. A three-phase pure sine wave inverter with external power board and three-phase power frequency transformer has been successfully operated on the 2000W inverter prototype. Drive board pressure 100V, applicable to the full bridge bus voltage below 100V occasions, temporarily does not support communication and fm., Weight: 44.0 pounds, Manufacturer: Xnuiasqe
