PoE Networking Industry PCB/PCBA

We have been engaged in the research and development of POE network power supply equipment for more than 10 years. The POE network power supply modules, power supplies, and PoE network switches we have developed are widely used by home and commercial users in more than 50 countries around the world.
POE (Power Over Ethernet) refers to the power of some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without making any changes to the existing Ethernet Cat.5 cabling infrastructure. etc.) while transmitting data signals, it can also provide DC power supply for such equipment. POE is also called a local area network-based power supply system (POL, Power over LAN) or active Ethernet (Active Ethernet). Sometimes it is also referred to as power over Ethernet. It uses existing standard Ethernet transmission cables to simultaneously transmit data and The latest standard specifications for electrical power and maintaining compatibility with existing Ethernet systems and users.

POE system composition: A complete POE system consists of two parts: power supply equipment (PSE, Power Sourcing Equipment) and power receiving equipment (PD, Powered Device). PSE equipment is a device that supplies power to Ethernet client devices and is also the manager of the entire POE Ethernet power supply process. The PD device is the PSE load that receives power, that is, the client device of the POE system, such as IP phones, network security cameras, APs, and many other Ethernet devices such as PDAs or mobile phone chargers (in fact, any power Devices not exceeding 13W can obtain corresponding power from the RJ45 socket). Based on the IEEE 802.3af standard, the two establish information connections about the connection status, device type, power consumption level, etc. of the powered device PD, and based on this, the PSE supplies power to the PD through Ethernet.
