Why does Ubiquiti use 24V PoE?

Why does Ubiquiti use 24V PoE?

Original Post: UniFi Access Points have always been built to be powered by PoE – it’s convenient, easy to setup and scalable. When we first started producing UniFi nearly 7 years ago, 24v Passive PoE was the standard in the operator space so we opted to use 24v passive for our Enterprise lines (UniFi, EdgeMAX).

Is PoE 24 or 48V?

802.3af Active PoE IEEE standard that supports low power devices and provides a maximum of 15.4W at the PSE. 24V Passive PoE Provides 24V power. 48V Passive PoE Provides 48V power.

How does Ubiquiti PoE injector work?

With PoE injectors, you send power and data through the Ethernet cable between the IP Camera and the injector. The data travels from the switch into the injector, which feeds it to the IP camera over 2 pairs of wires in the Ethernet cable.

Is PoE always 48v?

POE can be anything up to 48 volts. While there are some standards (802.3af), there are many systems which run lower voltages – 12 volts is common.

What voltage is Power over Ethernet?

Power over Ethernet is injected onto the cable at a voltage between 44 and 57 volts DC, and typically 48 volts is used. This relatively high voltage allows efficient power transfer along the cable, while still being low enough to be regarded as safe.

Is PoE always 48V?

Can I use a 48V PoE on 24V?

If your PoE device uses the PoE standard 48V 802.3af or 802.3at, it is considered to use active POE. This includes devices such as cameras and radio antennas that run on 24V PoE.

What voltage is PoE 802.3 af?
