Fuhjythy 50HZ Inverter 12V to 220V Sine Wave Inverter Driver Board 500W with Voltage Regulator

Power transformer is suitable for 800 w, the largest output power 500 w. Small transformer can't be output power, such as 50 w transformer cannot output power 80 w. Have input reverse connect protection function, With 10 v low voltage under-voltage protection function. Voltage stabilizing function: when the transformer is close to 12 v, no voltage stabilizing function, the output pulse, voltage stabilizing function for 8 v to 10 v transformer is, there are fine for the customer to adjust the voltage, voltage stabilizing function to meet the 220 v to 220 v voltage sampling board Output frequency: 50 hz, could be 'tuned' (before shipment has been adjusted to 50 hz), Output voltage, adjusted to about the 220 v before shipment, this kind of ac side voltage regulator has fluctuated. With a small fan when can in transformer output capacitance with fixed waveform, can output approximately sine wave, but a capacitive consume a certain amount of power, reduce the conversion efficiency, do not bring the perceptual load, plus a capacitor is not recommended.
