PoE Splitter 48V to 5V 2.4A Gigabit Power Supply Module
PoE Splitter 48V to 5V 2.4A Gigabit Power Supply Module
PoE Splitter 48V to 5V 2.4A Gigabit Power Supply Module with Isolation
Power your non-PoE devices over an Ethernet cable with ease using this Gigabit PoE Splitter. This compact isolation module converts a 48V Power over Ethernet input down to a clean, stable 5V / 2.4A DC output — perfect for powering Raspberry Pi boards, IP cameras, wireless access points, and other low-voltage devices without running a separate power cable.
Key Features
- Gigabit Ethernet Support: Full 10/100/1000 Mbps data pass-through — no speed compromise while splitting power.
- Isolated Power Conversion: Built-in isolation circuitry separates the power path from the data path, protecting your connected devices from electrical interference and voltage fluctuations.
- Input Voltage: 48V PoE (IEEE 802.3af/at compatible)
- Output Voltage: 5V DC
- Output Current: Up to 2.4A (12W)
- Compact & Plug-and-Play: No configuration required — simply connect and go.
- Wide Compatibility: Works with standard 802.3af/at PoE switches and injectors.
Ideal Applications
- Powering single-board computers (e.g. Raspberry Pi) via Ethernet
- IP surveillance cameras and wireless access points
- Network-attached devices in hard-to-wire locations
- Home automation hubs and IoT devices

Frequently Asked Questions
Q: What does a PoE Splitter do and how does the 48V to 5V isolation module work?
A: A PoE splitter receives Power over Ethernet (48V) from a PoE switch or injector through a standard RJ45 cable, then separates the electrical power from the data signal. This module steps down the 48V input to a stable 5V / 2.4A DC output while passing the Gigabit Ethernet data through untouched — letting you power devices that don't have built-in PoE support without a separate power adapter.
Q: Is this PoE splitter compatible with my existing PoE switch or injector?
A: Yes — this splitter is designed to work with standard IEEE 802.3af and 802.3at compliant PoE switches and injectors that supply 48V. It supports Gigabit speeds (10/100/1000 Mbps), so it is compatible with the vast majority of modern PoE networking equipment.
Q: Why is the isolation feature important in this PoE power supply module?
A: The built-in isolation separates the power conversion circuitry from the data path, which helps protect your connected devices from electrical noise, ground loops, and voltage spikes that can occur over long cable runs. This makes it a safer and more reliable choice compared to non-isolated PoE splitters, especially in professional or semi-permanent installations.
Q: What devices can I power with the 5V 2.4A output?
A: Any device that accepts 5V DC power at up to 2.4A — such as Raspberry Pi single-board computers, mini PCs, IP cameras, small wireless routers or access points, and various IoT or smart home devices — can be powered via this PoE splitter module.
