This driver board easy to install, high efficiency. just find a transformer, input AC 220 V to test this board, it will output double 12 V (12V-0-12V) you can choose our board driver.

The output power of the inverter is the actual efficiency of your transformer, but the maximum power must be below or equal to the power of the conductor board (300 W).
It does not mean that our driver board with 1000W transformer can output 1000W, the maximum output is recommended to use the valid range, 300W driver board supports a maximum output of 300W power, 600W driver board 12 V output recommendations with less than 500 W, but in addition to cooling fan, otherwise it will burn pipe field.
Before your shipment have been tested and debugging, 50Hz delivery frequency. Chips: IRS2153D
Applicable Transformers: steel core transformer 220V Variable 12V ~ 0 ~ 12V (if it is not the correct voltage, the output will be wrong, it is not 220V output ,) 12V-0-12V connect circuit board port (A + B), power port (input) connect the battery, you can output AC 220V, radiator height 35mm!
Protection: reverse battery protection, try to use all the power plus the cooling fan, help cooling tube feed good.
