ขาย 50HZ อินเวอร์เตอร์ 12V ถึง 220V คลื่นคลื่นอินเวอร์เตอร์บอร์ดไดร์เวอร์ 500W ราคาที่ดีที่สุด

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. 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 is not recommended. 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) size:88 x 72 x 46mm Material:ABS colour:Green+white Package Contents: 1 x inverter drive boardOnly the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
