Maximum Reliability: Your Network Runs. Always.
The core feature of the ALFA Network APOE03 is its redundancy. Thanks to two independent power inputs – a standard barrel jack and a robust screw terminal – you can connect the device to two separate power sources. Connect it to the main grid and an emergency Power Supply (UPS) or two different circuits. If one source fails, the other takes over immediately and without interruption. This makes it the perfect fail-safe PoE Injector redundant for critical systems such as IP Cameras, important WiFi Access Points, or sensitive IoT sensors.
Universally Applicable: The PoE Injector for 12V, 24V, and More
Forget compatibility issues. The extremely wide voltage input of 5 Volts to 57 Volts makes the APOE03 a true all-rounder. You can easily operate it in vehicles, campers, or on boats with a 12V or 24V battery. It works just as well in industrial control cabinets with 24V systems or with a 48V Power Supply for standard PoE applications. This enormous flexibility makes it the first choice if you are looking for a versatile PoE Adapter with 12V input or for other voltage levels.
Power and Data via One Cable – Simple and Robust
With the APOE03, you drastically simplify your Network installations. Instead of laying two Cabling (network and power) to a device, you only need a single Ethernet Cable. This not only saves time and money during installation but also ensures clean and tidy Cabling. The robust housing with practical mounting tabs is specifically designed for fixed and permanent installation, not just for the desktop.
Important Notes for Safe Operation
The APOE03 is a passive PoE Injector. This means it does not perform automatic negotiation (handshake) with the end device but applies the input voltage directly to the wires of the network cable. This is efficient but carries a risk: make absolutely sure that the voltage of your power source matches the requirements of your end device. Connecting a non-PoE device or using an incorrect voltage can permanently damage the connected device. Therefore, always check the specifications of your device before connecting it.

Frequently Asked Questions (FAQ)
What does 'redundant PoE Injector' mean?
A redundant PoE Injector like the ALFA APOE03 has two independent power inputs. If one power source fails, the device automatically switches to the second source, ensuring uninterrupted operation of the connected network device. This is crucial for critical systems such as IP Cameras.
Which devices can I operate with the ALFA APOE03?
You can operate passive PoE-enabled devices that require a voltage between 5V and 57V and can handle a data rate of 100 Mbps. Typical examples include IP Cameras, IoT sensors, VoIP phones, and many WiFi Access Points that do not require a Gigabit standard.
What is the difference between passive and active PoE?
Passive PoE (as with the APOE03) permanently applies the input voltage to the Ethernet wires without checking if the end device is compatible. Active PoE (according to IEEE 802.3af/at standard) first performs a 'handshake' to check compatibility and power requirements, which prevents device damage.
Can I use the APOE03 in a car or motorhome?
Yes, absolutely. Due to its wide voltage input range (5V-57V DC) and screw terminal connection, it is ideal for operation with a 12V or 24V vehicle battery, for example, to power a mobile WiFi Access Point.
Do I need a separate power supply for the APOE03?
Yes, the ALFA APOE03 is supplied without a power adapter. You must provide one or two suitable DC power sources whose voltage and power meet the requirements of the end device.
Why should I use the APOE03 instead of a PoE Switch?
A PoE Injector is a cost-effective solution if you only need to power a single device and already own a normal Ethernet Switch. It is ideal for selectively upgrading an existing network with redundancy for a critical device.
