The 12V Transformer 5A AC to DC Power Supply is a regulated power conversion unit designed to deliver stable 12V DC at up to 5A current. It steps down and rectifies AC mains voltage (110–240V) into a reliable DC output, making it suitable for Arduino and ESP32 projects, LED lighting, CCTV cameras, routers, robotics kits, battery charging circuits, and industrial automation systems. Available as SMPS modules, desktop adapters, and open-frame power supplies, the 12V 5A unit provides short-circuit, over-voltage, and overload protection for safe operation. Its compact design, high efficiency, and durability make it an essential component for IoT devices, embedded electronics, and industrial controllers. NeoGiga India supplies genuine, RoHS-compliant 12V 5A transformers with options for bulk orders, institutional packs, and nationwide delivery to support OEMs, startups, and educational institutes.
