When it comes to choosing between a PoE to 12 volt converter and a PoE to 5 volt converter, it is important to understand the key differences between these two options. Let us take a closer look at some of the important aspects to consider when comparing these converters:

4.1. Output voltage: The main difference lies in the output voltage supplied by each converter. The PoE to 12 volt converter delivers 12 volts, while the PoE to 5 volt converter supplies 5 volts. It is crucial to check the specifications of the devices you want to power so that you choose the converter that matches their voltage requirements. The supply voltage is usually shown on the device’s original power adapter. If it is not, a quick Google search should give you the right information.

4.2. Output current: Besides the output voltage, it is also important to take into account the output current required by the devices. Different devices have different current requirements. Make sure the PoE converter you choose can supply enough current to power the connected devices properly. The converter’s specifications must match the needs of your devices.

4.3. Compatibility and flexibility: Both types of PoE converter offer a high level of compatibility with PoE equipment that complies with the IEEE 802.3af or 802.3at standards. This gives you flexibility in your choice of devices and makes integration into existing infrastructure easier. Be sure to check that the converter is compatible with your PoE equipment and its associated standards.

When choosing between a PoE to 12 volt converter and a PoE to 5 volt converter, it is essential to take into account the specific needs of your devices, particularly in terms of voltage and current. We recommend that you consult the specifications of the devices you want to power and choose the converter that best meets their requirements.

5. Use cases and practical examples

PoE to 12 volt and PoE to 5 volt converters offer a practical way to power a range of devices in different fields. Here are a few common use cases and practical examples to illustrate how useful they are:

1. Door intercoms and intercom systems: Door intercoms and intercom systems are often powered by PoE to 12 volt converters. These converters provide a stable power supply to the intercom units, enabling two-way audio communication between visitors and residents. PoE power removes the need for separate electrical wiring and simplifies installation.

2. IP surveillance cameras: IP surveillance cameras are often powered by PoE converters when they do not have built-in PoE power. PoE to 12 volt or PoE to 5 volt converters are used depending on the cameras’ specifications. They power the cameras and carry the video streams at the same time over a single Ethernet cable, simplifying the cabling and installation of security systems.

3. Wireless access points: Wireless access points used to provide Wi-Fi connectivity are also powered by PoE converters. PoE to 12 volt or PoE to 5 volt converters are used depending on the needs of the access points. This approach avoids having a dedicated power supply for each access point, reducing the cost and clutter of installations.

4. Outdoor lighting: Outdoor lighting systems, such as street lamps, floodlights or garden lights, can be powered by PoE to 12 volt converters.

6. Power limitations

It is important to note that network cables have a limit to the power they can handle efficiently. This limit is mainly determined by the cable’s conductor cross-section, its shielding and its build quality. Standard Ethernet cables, such as Category 5e or Category 6 cables, are designed to carry data signals at specific frequencies and to power devices with a limited amount of power. So when you use PoE converters, it is essential to take into account the total power required by your connected devices and to make sure the network cable used can handle that power load.

If the power demanded exceeds the cable’s capabilities, this can lead to degraded signal quality, interference or even a complete failure of both data transmission and power. In such cases, we recommend using higher-category cables, such as Category 6A or Category 7 cables, which offer better power handling and optimal performance for PoE applications.

It is also important to note that the length of the cable can affect the power available at the other end. The longer the cable, the more likely power losses are to occur because of resistance and signal attenuation over the distance. We therefore recommend keeping cables as short as possible to minimise power losses and ensure reliable operation of PoE-powered devices.

7. Conclusion
