Detail Description

12V UPS Circuit is an electronic power backup solution designed to automatically switch to a battery source when the main power supply fails, ensuring continuous and stable 12V DC output. The circuit typically includes a charger section, battery protection, automatic changeover control, and voltage regulation.

This UPS circuit is widely used to power WiFi routers, CCTV cameras, access control systems, alarm panels, IoT devices, and embedded electronics. When mains power is available, the circuit powers the load and charges the battery simultaneously. During power failure, it instantly switches to battery mode without noticeable interruption.

The circuit can be built using components such as relays or MOSFETs, voltage regulators, charging controllers, and protection modules. It supports sealed lead-acid (SLA) or Li-ion battery systems (design dependent). Due to its reliability and simplicity, it is ideal for students, hobbyists, technicians, and professionals working on power backup and automation projects.
