PoE (Power over Ethernet) - is a technology that allows you to transfer power and data through a single Ethernet cable. All that is required is to connect a PoE-issuing device to a PoE-powered device via an RJ-45 network connector. Paired with a controller board, this module will allow you to power your project via Ethernet.
PoE has many advantages for use in different projects:
You can save time and money electrical power cables with network cables, which do not require a qualified electrician to fit them, and can be located anywhere.
Without being bound to an electrical outlet, devices such as IP cameras and wireless access points can be fitted to where they are most needed and be easily moved.
POE is designed to protect network equipment from overload, insufficient power or improper installation.
POE power comes from a central and universally compatible source, not from a collection of distributed wall adapters.
Having power on the network means that installing and distributing network connection is simple and efficient.
Active PoE - is an intelligent workflow that helps equipment to save energy through automatic remote power supply control, which allows you to avoid equipment breakdowns and work longer.
So, before applying power to the desired device, the active PoE source of the 802.3af/at standard (can be an adapter or switch) checks and recognizes the following:
1. Does device supports PoE? If there is no support for it, the power over the twisted pair will simply not be supplied.
2. Checks the voltage consumed by the device, and after setting the power class, it will supply only the required voltage value to the connected port.
