48V to 12V POE Splitter — stable DC conversion with built-in protections What it does Converts 48V PoE input to a regulated 12V DC output using a standard DC 5.5 x 2.1 mm connector. Provides isolated design for enhanced safety and includes protections against overcurrent and overheating. Delivers stable and efficient voltage regulation so high-powered devices run reliably from PoE sources. Key benefits — why you need it Power non-PoE 12V devices from existing PoE switches or injectors without running separate AC power lines. Reduce cabling and installation cost by centralizing power over Ethernet while keeping device voltages correct and stable. Protect connected equipment with isolation and built-in overcurrent/overheat safeguards to minimize downtime and equipment risk. What makes it stand out Standard DC 5.5 x 2.1 mm output for broad compatibility with cameras, routers, and other 12V devices. Isolated internal design to reduce interference and improve safety between PoE input and DC output. Multiple protection mechanisms to prevent damage from excessive current or temperature rises. Compatibility and intended users Designed for networking equipment, IP cameras, wireless routers, access points, and any 12V device using a DC 5.5 x 2.1 mm jack. Suited to enthusiasts, integrators, and IT professionals who need a reliable PoE-to-12V power solution. Installation and use Connect to a 48V PoE source and plug the 12V DC 5.5 x 2.1 mm output into your device — no additional power supply required. Works well in rack-mounted network setups, wall-mounted camera installations, and distributed networking points where AC outlets are limited. Practical use scenarios Home security: Power a 12V CCTV camera from a PoE switch to eliminate separate power runs and simplify installation. Office Wi-Fi: Feed a 12V wireless router or access point from a central PoE source to streamline cabling and backup power management. Small business or branch sites: Power network appliances in locations without convenient AC outlets while maintaining safety and device protection. Performance and reliability Engineered for stable 12V output and efficient conversion from 48V PoE sources, with protective features to maintain long-term operation and device safety. Suitable environments Office networking, retail locations, home security systems, small enterprise deployments, and other environments where PoE is available but devices require 12V DC.
