Ubiquiti 48V PoE Adapter in Kenya – POE-48-24W-G Gigabit PoE Injector

 

The Ubiquiti 48V PoE Adapter is a Power over Ethernet injector designed to deliver 48V DC power and Ethernet connectivity through a single network cable to compatible Ubiquiti equipment. The main Gigabit model is the POE-48-24W-G, which outputs 48V DC at 0.5A, providing up to 24W of power. 

The Gigabit version is particularly useful for installations where a compatible access point, outdoor radio or other network device needs PoE but the existing router or switch does not provide the required power. It allows the network to retain a non-PoE switch while adding power between that switch and the remote device.

An important distinction is that the POE-48-24W-G is not the same product as Ubiquiti's newer U-PoE 15W adapter, even though both output approximately 48V. The POE-48-24W-G delivers 48V at 0.5A and is rated around 24W, while U-PoE outputs 48V at 0.32A.

What Is a Ubiquiti 48V PoE Adapter?

A 48V PoE adapter, commonly called a PoE injector, takes ordinary Ethernet data from a router or switch and adds electrical power before sending the connection to a compatible powered device.

A typical installation looks like:

Router / Network Switch

↓

Ethernet Cable

↓

LAN Port – Ubiquiti POE-48-24W-G

↓

PoE Port

↓

Ethernet Cable carrying Data + 48V Power

↓

Compatible Ubiquiti Device

The adapter itself connects to an AC electrical outlet.

This means the remote device does not need a separate electrical socket beside it.

48V DC at 0.5A Output

The POE-48-24W-G provides:

48V DC @ 0.5A.

Using:

Power = Voltage × Current

gives:

48V × 0.5A = 24W

Therefore, the adapter belongs to Ubiquiti's 24W 48V PoE family.

This does not mean every device consuming less than 24W is automatically compatible. Voltage, pinout and PoE method must also match.

Gigabit Ethernet

The G in POE-48-24W-G is important because this model supports Gigabit Ethernet. 

A typical Gigabit network can therefore use:

Gigabit Router

↓

Gigabit Switch

↓

POE-48-24W-G

↓

Gigabit-compatible Ubiquiti device

This helps avoid creating an unnecessary 100Mbps bottleneck in the wired connection.

POE-48-24W-G vs POE-48-24W

Ubiquiti has also offered a POE-48-24W version without the G suffix.

Feature	POE-48-24W-G	POE-48-24W
Voltage	48V	48V
Current	0.5A	0.5A
Power	24W	24W
Gigabit Ethernet	Yes	No
Powering	2-pair	2-pair
Remote Reset	No	No
Surge Protection	Yes	Yes

The non-Gigabit POE-48-24W is specifically listed by Ubiquiti without a Gigabit LAN port, while the POE-48-24W-G provides Gigabit connectivity. 

For modern Gigabit network installations, the POE-48-24W-G is generally the more appropriate variant when the powered device is compatible.

2-Pair Power Delivery

The POE-48-24W-G uses two-pair power delivery.

Ubiquiti specifies:

Pins 4 and 5 → Positive (+)

Pins 7 and 8 → Negative (-). 

It does not use four-pair powering.

This electrical configuration is an important part of compatibility and should be checked alongside voltage and wattage.

Passive PoE – Important Compatibility Note

The POE-48 family should not be treated as interchangeable with every device labelled "PoE."

Ubiquiti has multiple powering families, including:

24V passive PoE

48V passive PoE

802.3af PoE

802.3at PoE+

802.3bt PoE++

These may use similar Ethernet connectors but have different electrical characteristics.

Therefore:

RJ45 connector compatibility does not guarantee PoE compatibility.

Always verify the exact powered device before connecting a 48V injector.

Ubiquiti 48V PoE vs 24V PoE

One of the most important distinctions is voltage.

Feature	48V POE-48-24W-G	24V POE-24-24W-G
Output Voltage	48V	24V
Output Current	0.5A	1A
Output Power	24W	24W
Gigabit Ethernet	Yes	Yes
Remote Reset	No	Yes
Reset Button	No	Yes
Powering	2-pair	2-pair
Positive	Pins 4/5	Pins 4/5
Negative	Pins 7/8	Pins 7/8

Both provide approximately 24W, but they do so at completely different voltages. Ubiquiti specifies 48V @ 0.5A for POE-48-24W-G and 24V @ 1A for POE-24-24W-G. 

Therefore, equal wattage does not mean the adapters are interchangeable.

Ubiquiti 48V PoE Adapter vs U-PoE 15W

The POE-48-24W-G should also be distinguished from Ubiquiti's current U-PoE.

Feature	POE-48-24W-G	U-PoE
Voltage	48V	48V
Current	0.5A	0.32A
Approx. Power	24W	15W class
Gigabit	Yes	Yes
2-Pair Power	Yes	Yes
Positive Pins	4/5	4/5
Negative Pins	7/8	7/8
Surge Protection	Yes	Yes

The U-PoE is rated at 48V @ 0.32A, while POE-48-24W-G provides 48V @ 0.5A. 

The correct adapter still depends on the powered device's specification rather than simply selecting the model with greater wattage.

48V PoE vs PoE+

A common mistake is assuming that a 48V 24W passive injector is automatically equivalent to an 802.3at PoE+ injector.

It is not safe to make that assumption.

PoE compatibility involves more than:

Voltage + wattage.

It can also involve:

IEEE negotiation

powered pairs

polarity

device detection

and

hardware-specific requirements.

For a modern UniFi access point explicitly requiring PoE+, use the PoE source Ubiquiti specifies for that model.

Built-In Surge Protection

The POE-48-24W-G includes difference-mode and common-mode surge protection.

Ubiquiti specifies:

Maximum surge discharge: 1,500A using an 8/20μs waveform

and

Peak pulse current: 36A using a 10/1000μs waveform. 

The adapter also specifies clamping protection of:

11V for data

and

60V for power.

These protections are useful for network installations, particularly where Ethernet cabling runs toward outdoor equipment.

Surge Protection for Outdoor Installations

The protection built into the PoE adapter should not automatically be considered a complete substitute for proper outdoor network protection.

For exposed installations, consider:

Outdoor-rated Ethernet cable

Shielded cable where appropriate

Proper grounding

Ethernet surge protectors

Correct cable routing

Lightning-risk management

This is particularly important for rooftop, mast, tower and building-to-building installations.

Wide 100–240V AC Input

The POE-48-24W-G accepts:

100–240V AC at 50/60Hz. 

This wide input range allows it to operate across many electrical systems.

The power cable is included, although the exact plug supplied can depend on market and package source.

80%+ Efficiency

Ubiquiti specifies an efficiency rating of:

80%+

for the POE-48-24W-G. 

The adapter converts AC mains electricity into regulated 48V DC output while also passing Ethernet data between its LAN and PoE connections.

Compact Design

The adapter measures approximately:

92 × 60 × 33mm

and weighs:

159g. 

This compact form factor makes it easy to install near:

Routers

Switches

UPS systems

network cabinets

or

desktop network equipment.

How to Connect the Ubiquiti 48V PoE Adapter

The connection order is straightforward:

Step 1: Connect the router or switch to the adapter's LAN/Data port.

Step 2: Connect the compatible powered device to the PoE port.

Step 3: Connect the adapter to AC power.

The architecture becomes:

Internet

↓

Router

↓

Switch

↓

LAN – POE-48-24W-G – PoE

↓

Compatible Powered Device

The powered output should only be connected to equipment confirmed to support the adapter's electrical specification.

Do Not Connect the PoE Port to a Computer

The powered PoE output should not be treated like an ordinary LAN port.

Do not casually connect it to:

Laptop Ethernet ports

Desktop PCs

ordinary printers

non-PoE switches

or other devices that are not designed to receive its PoE output.

The LAN/Data input connects toward the router or switch.

The PoE output connects toward the compatible powered device.

Ubiquiti 48V PoE Adapter for Access Points

A 48V PoE injector can be useful for compatible Ubiquiti access points when a PoE switch is unavailable.

For example:

Router

↓

Non-PoE Gigabit Switch

↓

POE-48-24W-G

↓

Compatible Ubiquiti AP

However, not every UniFi AP should automatically be powered using this injector.

Modern UniFi models may specify PoE, PoE+, PoE++ or another particular power requirement.

Always check the exact AP model first.

Ubiquiti 48V PoE Adapter for Outdoor Radios

The POE-48-24W-G can also be useful for compatible outdoor networking devices requiring its 48V powering arrangement.

A typical installation can be:

Indoor Router

↓

Network Switch

↓

48V PoE Adapter

↓

Outdoor Ethernet Cable

↓

Compatible Outdoor Device

This allows the injector and AC connection to remain indoors while the remote network device receives power through Ethernet.

The injector on each side must match the particular radio used.

Do not assume both ends use the same voltage simply because both radios are Ubiquiti products.

Using the 48V PoE Adapter with MikroTik

The LAN side can operate behind a MikroTik router or switch.

For example:

The same applies to TP-Link networking equipment.

A possible installation is:

TP-Link Router

↓

TP-Link Gigabit Switch

↓

POE-48-24W-G

The switch provides ordinary Ethernet data, while the injector adds electrical power.

Using the Ubiquiti 48V PoE Adapter with Starlink

The adapter can also form part of a Starlink-based network.

For example:

Starlink

↓

Router / Gateway

↓

Gigabit Switch

↓

POE-48-24W-G

↓

Compatible Ubiquiti AP or Radio

The injector powers the downstream network device.

It does not increase Starlink internet speed and should not be assumed to power the Starlink dish itself.

A fibre installation could use:

Fibre ONT

↓

Router / Firewall

↓

Non-PoE Gigabit Switch

Compatible Access Point

This is one of the major benefits of a dedicated injector: an existing non-PoE switch can remain in service.

PoE Adapter vs PoE Switch

Feature	48V PoE Adapter	PoE Switch
Best for	One/few devices	Multiple devices
Dedicated power	Yes	Shared PoE budget
Initial cost	Usually lower	Higher
Cabling at scale	More clutter	Cleaner
Central management	Limited	Better
UPS integration	Possible	Easier centrally
Scalability	Limited	Better

For a single compatible device, the adapter can be a simple solution.

For a network containing many APs, cameras or other PoE devices, a suitable PoE switch usually provides a cleaner architecture.

When Should You Use a Ubiquiti 48V PoE Adapter?

The POE-48-24W-G is useful when:

Your switch has no PoE

You need to power one compatible device

A compatible existing injector has failed

You want dedicated power for one device

Your existing switch has Ethernet capacity but no suitable PoE

You need a Gigabit data path

It can therefore avoid replacing an otherwise functional non-PoE network switch.

When Should You Use a PoE Switch Instead?

A PoE switch is generally preferable when installing:

Several access points

Multiple IP cameras

VoIP phones

door-access equipment

large hotel networks

school networks

enterprise Wi-Fi

For example, ten separate injectors require ten AC connections and twenty injector-side Ethernet connections.

A suitably sized PoE switch can centralize this infrastructure.

POE-48-24W-G Advantages

The Ubiquiti 48V Gigabit PoE adapter provides:

48V DC output

0.5A capacity

24W output

Gigabit Ethernet

100–240V AC input

surge protection

compact installation

shielded RJ45 sockets

included power cable

and a straightforward way to add power to a compatible Ethernet device.

It can be particularly economical when only one compatible PoE device needs power.

POE-48-24W-G Limitations

The main limitation is that it should not be treated as a universal PoE injector.

It does not provide:

Remote reset

A reset button

or

four-pair powering. 

It should also not automatically be substituted for a modern standards-based PoE+ or PoE++ source simply because its voltage and wattage appear sufficient.

Device compatibility comes first.

Who Should Buy the Ubiquiti 48V PoE Adapter?

The POE-48-24W-G is particularly useful for:

Network installers

WISPs

Businesses

Home networks

Wireless installers

Replacement PoE-injector requirements

Compatible Ubiquiti equipment

Networks using non-PoE switches

It is especially useful when Gigabit Ethernet is required alongside a dedicated 48V power source.

How to Choose the Correct Ubiquiti PoE Adapter

Before purchasing, check:

1. Exact device model

Identify the full model number.

2. Required voltage

Confirm whether it needs 24V, 48V or another voltage.

3. Maximum consumption

Confirm that the available power is sufficient.

4. PoE method

Determine whether it requires passive PoE, 802.3af, PoE+, PoE++ or another implementation.

5. Ethernet speed

Confirm whether Gigabit is sufficient or whether the device needs 2.5GbE or faster.

This prevents buying an injector that supplies enough watts but uses the wrong electrical arrangement.

Why Buy Ubiquiti 48V PoE Adapters from Orbitlink Solutions?

The most important part of buying a PoE adapter is matching it correctly to the device being powered. A 24V passive injector, POE-48-24W-G, U-PoE, U-PoE+, and U-PoE++ should not automatically be treated as interchangeable simply because all of them use RJ45 Ethernet connections.

For an existing network, the POE-48-24W-G can be particularly useful because it provides Gigabit Ethernet while adding a dedicated 48V DC power source. This can allow a normal non-PoE switch to continue operating instead of being replaced solely to power one compatible device.

Orbitlink Solutions can help match the injector with compatible Ubiquiti equipment, Ethernet cabling, routers, switches and related network accessories according to the specific installation.

Watch the Ubiquiti 48V PoE Adapter Video

The POE-48-24W-G is fundamentally a 48V, 24W-class Gigabit power injector. Its role is to place the required electrical power onto the Ethernet cable while maintaining the data connection between the network switch and a compatible powered device. Ubiquiti specifies 48V DC at 0.5A, Gigabit Ethernet and two-pair powering. 

One of the most important purchasing considerations is the G suffix. Ubiquiti's POE-48-24W-G supports Gigabit Ethernet, whereas the POE-48-24W variant is documented without a Gigabit LAN port. For a compatible device capable of Gigabit networking, selecting the Gigabit version prevents the injector from unnecessarily reducing the wired link to Fast Ethernet speeds. 

Compatibility remains more important than wattage alone. A 48V 24W injector should not automatically be connected to every Ubiquiti access point or radio. Ubiquiti equipment spans several power architectures, including 24V passive PoE and modern PoE/PoE+/PoE++ products. Always identify the exact powered device before selecting the adapter.
