Low Frequency 50Hz Inverter Driver Board 300W Iron Core Transformer DC 12V To 220V AC Power Supply Module Drive Board

Note : this module it is a driver board . not a boost board! Input voltage: DC12V Output voltage: connected with a center tap 220V to 12V + 12V transformer wiring figure : the 12v connected to the board output The transformer input 220V line voltage .there 220v 300W model use power : le than 300W using two P75NF75(75A TO-220PACKAGE)power PET drive The frequency of this board will fluctuate due to input voltage fluctuations (50HZ) 1. The 12V terminal of the transformer must be a 12V + 12V double 12V structure (the 12V terminal is a three-wire structure) 2. A single 12V (only two wires at the 12V end) cannot be used. 3. The wiring must be connected to all the transformers before the power can be tested. Do not power on while connecting. 4. The output of this inverter board is square wave, which is not suitable for fan motor load, because the fan with square wave will generate heat and buzz. Low speed and other phenomena. A series of electric motors such as hand drills can be used. 5.If you want to output enough power, you need to ensure the input power, small batteries, thin input lines, and small transformers.It is impoible to output high power. 6. The leakage inductance transformer cannot be used for this board, such as a microwave oven transformer, a p station, and a transformer on a launcher. There are several silicon steel sheets inserted between the two primary stages of such transformers, and the no-load current and power consumption Very high. 7. This board does not support the removed transformer on the UPS. 8. Do-it-yourself transformers are not suitable for this board. Most of the transformers made by my own friends do not meet the standard due to the small number of turns. As a result, after connecting the driver board, the no-load current is huge and the driver board is burned. 8. This board is strictly forbidden to connect high frequency transformer, otherwise it will cause damage to the drive board.
