I have a UPS circuit. I want to replicate it. I want its circuit schematics, Bill of materials, and Gerber file. The circuit is designed to support a wide AC power range, from 110V to 220V, providing flexibility for various power sources. It includes voltage surge protection to shield the device from fluctuations. The battery features overcharge protection, promoting long-term battery health. When AC power is available, the circuit operates with AC power and charges the battery. In the absence of AC power, it seamlessly switches to a battery backup. It should have a step-up converter during battery backup as one the output should be 24V. A safety cut-off activates if the battery voltage drops below 10V, ensuring reliable performance and protection for the connected device. The first...
