Why Choose an Isolated PoE Splitter?
Unlike non-isolated splitters, an isolated module uses a transformer-based DC-DC converter to fully separate input and output circuits. This protects your devices from common-mode noise and voltage transients present on network cabling — especially important in longer cable runs or electrically noisy environments such as industrial or outdoor security installations.

Frequently Asked Questions
Q: What is a 48V to 5V PoE splitter and what does it do?
A: A PoE (Power over Ethernet) splitter taps the 48V DC power delivered over an Ethernet cable and converts it to a lower voltage — in this case 5V DC — so you can power devices that don't have a built-in PoE port. This isolated module uses a galvanic DC-DC converter to keep input and output circuits fully separated, providing cleaner, safer power to your connected device.
Q: Which devices is this PoE splitter compatible with?
A: This splitter is compatible with any IEEE 802.3af or 802.3at PoE switch or injector on the input side, and powers any device that accepts a regulated 5V DC input — including security cameras, IP phones, wireless access points, and single-board computers like the Raspberry Pi.
Q: Why is isolation important in a PoE splitter module?
A: Galvanic isolation prevents ground loops and shields your downstream device from voltage spikes or noise on the network cable. This is especially valuable in longer cable runs, outdoor installations, or environments with electrical interference, where a non-isolated splitter could allow unwanted currents to affect sensitive electronics.
Q: Is this PoE splitter easy to install?
A: Yes — it's a plug-and-play inline cable module. Simply connect the Ethernet input from your PoE switch or injector and plug the 5V output into your device. No tools, configuration, or additional software are required.
