POE75U Series, Power over Ethernet (PoE)

Power over Ethernet (PoE) power supplies are an innovative solution that allows designers to transmit both electrical power and data signals over a single Ethernet connection. This technology enables remote devices to be powered through the Ethernet cable, eliminating the need for local power sources such as batteries or separate power adaptors. With PoE, power is delivered to devices through the same Ethernet cable that transmits data, providing a simple, reliable, and cost-effective solution for powering remote devices. This approach eliminates the need for additional power cabling, reducing installation complexity and costs. Moreover, PoE allows for centralized power management, enabling remote devices to be monitored and controlled more easily. The PoE power supply converts the AC or DC power from the mains into low-voltage DC power suitable for powering Ethernet-connected devices. This is achieved through the use of a PoE injector, which sends power and data signals to the remote device through the Ethernet cable. The remote device receives the power and data signals through a PoE splitter, which separates the power from the data signal and delivers the correct voltage and current to the device. PoE power supplies have become increasingly popular in a variety of applications, including IP cameras, wireless access points, VoIP phones, and other networked devices. They provide a flexible and scalable solution for powering remote devices, allowing for easy installation and maintenance. In summary, PoE power supplies offer a convenient and efficient way to power remote devices through an Ethernet connection. By eliminating the need for additional power cabling and local power sources, PoE simplifies installation and maintenance, reduces costs, and enables centralized power management. With their versatility and reliability, PoE power supplies have become an essential component in modern networked systems.
