This is a hand-drawn schematic diagram of a 0-30V/0-3A dual DC adjustable power supply, designed for constant voltage and constant current output. I created this many years ago while working on an export product for a company. Due to strict technical confidentiality policies, the full schematic cannot be shared publicly. However, the drawing accurately reflects the core principle of the product, and it's a complete representation of the circuit design. If you're interested in understanding the internal workings or analyzing the design, feel free to take a closer look. It's a great example of how such power supplies are structured and operated.
Utility pole is a tall structure that supports overhead power lines, telephone lines, or other utilities. Typically made of wood, metal or concrete, these poles are installed along roads, streets and highways to provide power and communications services to homes and businesses. Utility poles are critical to the distribution of electricity and telecommunications throughout the community.
