Low frequency 50Hz Inverter Driver Board 300W Iron Core 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 wiring figure : the 12v connected to the board output The 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 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 s 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 s.It is impoible to output high power. 6. The leakage inductance cannot be used for this board, such as a microwave oven , a paging station, and a on a launcher. There are several silicon steel sheets inserted between the two primary stages of such s, and the no-load current and power consumption Very high. 7. This board does not support the removed on the UPS. 8. Do-it-yourself s are not suitable for this board. Most of the s 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 , otherwise it will cause damage to the drive board.
