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

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. 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 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. 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.
