Description
Power Inverter 12v 50HZ to AC220 Square Wave Output Variable Frequency Transformer Low Frequency Inverter Transformer
Product Description
This motherboard is connected to a dual 12V transformer to turn the 12V DC voltage into a 220V square wave AC voltage output. Adapt to the power transformer within 300W. This board is a special product and needs to know the relevant technology before it can be installed and used normally.
The board has been calibrated with a digital oscilloscope before shipment. Generally, do not adjust the potentiometer. The potentiometer on the board is used for frequency trimming (50HZ). The frequency will fluctuate due to input voltage fluctuations! !
