![]() re: testing the egs002 inverter board. ![]() i rewind this transformer to 0 7.5 220v to use for my egs002 inverter which i believe it should give me at least 500watt on 12v system. i savaged a transformer from an old ups, the transformer is 15 0 15 220v which is meant for a 24vdc 1.2kv ups.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. it uses asic eg8010 as control chip and ir2110s as driver chip. Webdescription egs002 is a driver board specific for single phase sinusoid inverter. over voltage: now, slowly turn the vfb variable resistor until the vfb voltage is more …. return the vfb to 3.0v and the egs002 should return to normal conditions. when the voltage gets to approximately 2.55volts, the red led on the egs002 will blink four times and all green led’s should turn off, meaning under voltage has occurred.if you look at it you will see a 12v to 320v step up push pull converter to do the voltage lifting, and then they use the 002 to do the 50hz sine wave. re: testing the egs002 inverter board « reply #60 on: march 22, 2016, 04:39:02 pm » the circuit you alluded to is a hf complete circuit.Egs002 Test Easyeda Open Source Hardware Lab
