Detailed POE power supply module

With the complexity of the network layout, the technical threshold is getting higher and higher. The POE power supply module is rising in the rapid development of network monitoring. With the increasingly diversified usage scenarios, POE power supply modules are also getting more and more. User attention.
What is a POE power supply module?
The POE power supply module is an integrated power supply module that can provide DC power to such devices while transmitting data to the terminal through a cable. PoE technology can guarantee existing ones while ensuring the safety of existing structured wiring. The normal operation of the network minimizes costs.
The role of the POE power supply module
Generally, under the stable Ethernet cabling infrastructure, equipment cannot be easily replaced because it will increase the cost. In order to optimize the above situation, POE power supply module technology emerges as the times require. The main function is to make no changes in the previous architecture. In this case, DC current can also be supplied when data signals are transmitted by IP phones, network cameras, wireless LAN access point APs, and the like.
Difference between POE power supply module and POE switch
Both the POE power supply module and the POE switch can supply power to the network terminal equipment, but there are still significant differences between them:
The 1POE power supply module supplies power to the device through the network cable, and the current is directly output. The POE switch negotiates with the device. The POE device outputs power. Otherwise, only data is exchanged.
2POE switches can work independently, can transmit data and power signals at the same time, and can be powered by connecting devices that need to be powered. The PoE power supply module needs to be used with the switch.
3 From the perspective of the network group network, the POE switch is more convenient, but the POE power supply module is simpler and the price is much lower than the POE switch.
Advantages of the POE power supply module
(1) Cost savings. Because the POE power supply module only needs to install one cable instead of two. In many cases, it needs to be installed where AC power is difficult to deploy. As devices connected to Ethernet increase, there is no need to provide local power to the device, which greatly reduces deployment costs and simplifies manageability.
(2) Easy to install and manage. Customers can automatically and securely mix legacy and POE devices across the network, seamlessly integrating with standard Ethernet and Fast Ethernet standard architectures.
(3) Easy management of network equipment. The wireless AP with the POE power supply module has a remote reset function.
(4) The device is easy to move. The POE power module can be moved to any location with a LAN cable and the movement has minimal impact on the workplace.
(5) Remote monitoring. The POE power supply module can be used to remotely monitor devices connected to the Ethernet.
(6) Security. Eliminates cumbersome AC power supply installation and maintenance, greatly improving construction safety and reducing construction and maintenance difficulties and costs.
POE power supply module classification
Standard and non-standard
Standard type power supply 48V, in line with 802.3af standard, 802.3at standard
Non-standard type common 24V, etc.
How to connect POE power supply modules
A complete POE system connection includes two parts: a power supply device (PSE, PowerSourcing Equipment) and a power receiving device (PD, PoweredDevice). Power supply equipment (PSE) such as: Ethernet switches, routers, hubs or other network switching equipment that support POE. Power receiving equipment (PD) such as: network camera (IPC), IP telephone, wireless LAN access point AP, etc.
As can be seen from the figure below, one port of the POE power supply module is connected to the socket, and the other port is connected to a power supply device such as a non-POE switch, a POE IP phone, a POE dome camera, a POE/non-POE AP access point, etc. The electric terminal device realizes that the data transmitted by the matching switch and the direct current carried by the switch are transmitted to the receiving end device to achieve the purpose of transmitting the data signal while providing the direct current.
