48V 0.5A PoE Injector Power Over Ethernet Adapter for Wireless Access Point for AP

What is POE?

POE (Power Over Ethernet) refers to the existing Ethernet Cat.5 cabng infrastructure don't do any changes,
transmit data signals for some based on IP terminal (e.g.,IP telephone,wireless LAN Access Point,webcams, etc.) ,
at the same time also provide such equipment with technology of Power supply.
The principle of POE  power supply through cable.
Standar ategory 5 reticle have four pair twisted-pair cable,but in l0M BASE-T and 100M BASE-T only use two of them.

Category 802.3af(POE) 8023.at(POE plugs) Classification 0~3 0~4 Maximum current 350mA 600mA PSE output voltage 44~57V 50~57V PSE output power ≤15.4W ≤30W PD input voltage 36~57V 42.5~57V PD maximum power 12.95W 25.5W Cabng requirements unsteuctured CAT-5e or better Power supply cable ne pair 2 2

The benefits of POE power supply:
1. The cost savings.Because it only need to install one cable rather than two.In many cases,
all need to install where is difficult to deploy AC power supply.
With the increase of the device connected to the Ethernet,
if do not need to provide the local power supply for equipment,
will greatly reduce the deployment cost,and simpfy its manageabity.

2. Easy to install and manage.Customers can automatically
and safely mixed use original equipment and POE equipment on the network,
able to coexist with the existing Ethernet cable.

3. Safety. POE power supply terminal equipment will only supply for the equipment needed power supply.
Only connected to the equipment needed power supply,Ethernet cable voltage will exist,
thus eminating the risk of electric leakage on ne.

4. Easy to manage network equipment.

IEEE80 2.3 af allows two usage:
1. Appcation of the free foot power supply, 4,5 foot connected are the anode, 7,8 feet connected are the cathode.
2. Appcation of the data feet power supply,add the power supply at the midpoint of the transmission transformer,
not affect the data transmission.In this way,ne pair 1,2 and ne pair 3,6 can be arbitrary polarity.

The standard does not allow apply the above two situations at the same time.
PSE (power supply equipment) can only provide a kind of usage,
but power appcation equipment PD must be able to adapt to the two cases.
