The original 220V line of transformer input has 220V voltage. Power consumption: 300 The board will fluctuate due to input voltage fluctuation (50HZ) 1. The 12V end of the transformer must be a 12V+12V dual 12V structure (the 12V end is a three-wire structure) 2. Single 12V (only two lines on the 12V end) cannot be used. 3. Wiring must be connected to all the wires of the transformer before the power can be tested. 4. The output of this inverter board is square wave, which is not suitable for fan motor type load, because the fan motor will generate heat and squeak. Low speed and so on. A series of electric motors for hand drills can be used. 5. If you want to output enough power, you need to ensure the input power, small battery, thin input line, small transformer, it is impossible to output high power. 6, leakage inductance transformer can not be used for this board, such as microwave oven transformers, paging station, transformer on the launch pad, there are more than a few silicon steel sheets between the two primary and secondary of this type of transformer, and no-load current, power consumption Very high. 7. This board does not support the removed transformer on the UPS. 8. The transformer that is self-wrapping is not suitable for this board. Most of the transformers wound by the friends themselves are less than the standard because of the number of turns. As a result, after the drive board is connected, the no-load current is huge and the drive board is burned out. 9. This board is strictly forbidden to connect high frequency transformer, otherwise the drive board will be damaged.
