The image shows a close-up of a green printed circuit board (PCB) with various electronic components attached to it. The board is rectangular in shape and appears to be made of metal. On the left side of the board, there is a white rectangular component with a small hole in the center. Next to it, there are several smaller electronic components such as capacitors, resistors, transistors, and integrated circuits. 

On the top right corner of the image, there has a blue button with the number "220" on it, which is likely used to control the power supply. On top of the green circuit board, on the top left corner, there appears to have a small white connector, which may be a power supply unit or a control panel.

There are also several other electronic components scattered throughout the board. Some of the components are black, while others are white. There are also two silver-colored knobs on the bottom right corner, which could be switches or switches. The overall appearance of the PCB is clean and well-maintained.
