Pure Sine Wave 12V To 220V Inverter Circuit Board Solar Converter Board 800W

Pure sine wave inverter circuit board 12V turn 220v1000w foot 700 watts sine wave circuit board.

PCB size 170*119*50mm single board weight 0.9G

The main transformer is two EC40 primary stage 8 power transistors with absolute solid material winded by copper strip. The rated power is 600 watts and the maximum power is 700 watts.

No load current is 300MA or so, fan is intelligent control, rotate speed varies with load power.

Protection function, short circuit protection, overload protection, high temperature protection, low voltage protection, over voltage protection.

Precautions 12V input and output are strictly prohibited, and it is strictly prohibited to merge into the market. Please use it in ventilated and dry areas.

Pure sine wave inverter circuit board 12V turn 220v1000w foot 750 watts sine wave circuit board.

The ed ST is used to dismantle the high power field effect transistor, and has been tested for a long time. ST power tube compatibility stability is relatively good. Too many domestic products are too afraid to use.

Functional description of 4 adjustable potentiometers on board

W1 multi cycle high precision adjustable resistor regulated output voltage between 180-230v

W2 blue and adjustable resistor can regulate the output voltage of two transformers ar rectification.

W3 Blue and adjustable resistor Input Sampling Voltage Adjustment can adjust the lowest operating voltage in the working voltage range, and the lowest closing voltage is the lowest 10 V by default. Close About

W4 Multi cycle high precision adjustable resistor. Pre-stage power transistor current sampling regulates pre-stage power transistor input overcurrent protection function overload protection clockwise power increase Note that if it is counterclockwise, it will not be able to carry 100 watts of power to protect the clockwise can be adjusted 20 circles to hear the click is to adjust 6 circles counterclockwise is about 800 watts of power.

Standard configuration 40A medium insurance two, such as carele, positive and negative connection, ar the insurance is burned, you can change it yourself.

InvertBoard test notes

12V to 220V inverters can only be connected to a 12V battery for testing. Do not connect other voltages exceeding 16V will damage the circuit board.

2 input the positive and negative pole must be optimistic about the standard, need to match 6 square copper wire length should not exceed 1 meters. Otherwise, the performance will be affected. Battery configuration 10AH takes 100 watts 20AH with 200 watts and so on.

3 Sinusoidal board has about 350 V DC high voltage. The bottom board must be insulated. Please do not put it on the board for power test. The leakage of the board will damage the circuit of the high voltage part of the circuit board. Good insulation materials such as plastic boards or foam board should be padded. No metal material should be touched on the circuit board during power test.

4 the inverter has no charging function. It is strictly forbidden to acce power on the output line, otherwise the consequences will be conceited.

5 although the inverter has short circuit overload protection function, electronic products can not be 100%. If the high-power electrical appliances are connected to the inverter board for protection and alarm, the electrical appliances must be disconnected in a short time to prevent damage to the circuit board.
