แผงวงจร12 V To 220 V Pure Sine Wave Inverter 500 W ตัวควบคุมแรงดันไฟฟ้า
NEW 1PC inverter 12v to 220V pure sine wave inverter Driver board 500W with voltage regulator
The input voltage: 10 v to 15 v
Output waveform: square wave sine wave (according to the use of transformer and 220 v voltage feedback decision no feedback square wave)
Quasi sine wave inverter driven plate
Need external 50 hz 220 v transformer 8-12 v transformer even greater than 10 v above the feedback voltage 220 v also may not be able to voltage stability low pressure side of a winding can (standard transformer silicon steel sheet)
Power transformer is suitable for 800 w the largest output power 500 w
Small transformer cant be output power such as 50 w transformer cannot output power 80 w
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
Have input reverse connect protection function
With 10 v low voltage under-voltage protection function
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 will consume a certain amount of power reduce the conversion efficiency do not bring the perceptual load plus a capacitor is not recommended
