Power Over Ethernet (PoE) is a technology that has revolutionized the networking industry. It allows for cost-effective and flexible installation of network devices in areas where traditional cabling systems would not be practical. PoE technology combines the power and data communication into one cable, eliminating the need for additional power cables and outlets. The PoE21-120 is a type of industrial power over Ethernet solution that is designed for applications requiring a higher-power output.The PoE21-120 is a bi-directional, passive power source that is capable of delivering power at up to 120W. It is designed to be compatible with a wide variety of network components such as access points, IP cameras, VoIP phones, and similar devices that require higher-power output. The PoE21-120 is designed for use in industrial and commercial environments that require a reliable power supply.One of the main benefits of the PoE21-120 is that it is a cost-effective way to power high-power network components. The system offers flexibility in terms of installation as it does not require additional power outlets or cabling. The plug-and-play design makes it easy to install and configure, with minimal disruption to existing network infrastructure.The PoE21-120 is based around a single cable that carries both power and data. The power transmission is achieved using power and data lines, which are combined into a single twisted pair. This allows for seamless integration of power and data communication. The PoE21-120 uses a standard four-pair power system, which means that multiple devices can be powered using a single cable.The PoE21-120 is also safer to use compared to traditional power sources. It does not require any electrical grounding, which eliminates the potential risks associated with using high-voltage electrical devices. The high-quality insulation and integrated over-current protection reduce the risks of accidental shorts or fire hazards.The working principle of the PoE21-120 is based on the power and data transmission being combined into one cable. A single power source (N + 1) is used to provide the power supply, while data is transmitted simultaneously via the four-pair system. The N + 1 power source ensures that the power supply remains stable and reliable, even under heavy loads.The PoE21-120 is a versatile and cost-effective power source for a wide range of applications. It is ideal for powering high-power network components, such as access points, IP cameras, VoIP phones, and similar devices. It is also suitable for applications in industrial and commercial environments, due to its advanced safety features. As it does not require any additional cabling or outlets, it is easy to install and configure. Furthermore, the use of the N + 1 power source ensures that the power supply remains stable and reliable, even under high loads.
