‘’Functional description of 4 adjustable potentiometers on board
W1 multi cycle high precision adjustable resistor regulated output voltage between 180-230v
W2 blue and white adjustable resistor can regulate the output voltage of two transformers after rectification.
W3 blue-white adjustable resistance input sampling voltage adjustment can adjust the operating voltage range of the lowest operating voltage, the lowest closing voltage default lowest 10 V off or so
W4 multi-loop high-precision adjustable resistor, front-stage power transistor current sampling adjust the input overcurrent protection function of the front-stage power transistor overload protection clockwise power regulation attention if the anti-clockwise adjustment is not able to carry 100 watts of power will be protected clockwise can be adjusted 20 turns to hear the beep is to adjust to the end and then reverse time The 6 turn of the needle is about 800 watts of power.
Standard configuration 40A medium insurance two, such as careless, positive and negative connection, after the insurance is burned, you can change it yourself.
Points for attention in test of inverter board
1 12V to 220V inverter can only be connected to a 12V battery test do not connect other voltage over 16V voltage will damage the circuit board
2 Input positive and negative poles must be optimistic about the standard 6 square copper wire length can not exceed 1 meter, otherwise affect the performance. Battery configuration 10AH takes 100 watts 20AH with 200 watts and so on.
3 Sinusoidal wave board has 350 V DC high voltage, the bottom board must be insulated do not put on the board power test, board leakage will damage the circuit board high voltage part. Should be padded with high insulation materials such as plastic board or foam board, no human body metal materials touching the circuit board during power-on test.
4 the inverter has no charging function. It is strictly forbidden to access power on the output line, otherwise the consequences will be conceited.
Although the inverter has short-circuit overload protection function, but the electronic products can not be 100%. If you have access to high-power electrical inverter board protection and alarm must be in a short period of time to disconnect electrical appliances to prevent damage to the circuit board
