One of the key technologies needed for the successful deployment of connected technology is Power over Ethernet (PoE). PoE is a protocol that allows Ethernet jacks to deliver power to connected devices through the same connector used for data. This protocol makes it possible to deploy powered devices such as IP phones, wireless access points, and IP cameras without the need for a dedicated power connection. The PoE standard is divided into several different classes, each of which defines the maximum power delivered to the end device. The POE21-240 is the most commonly used PoE standard, and it is capable of delivering up to 240 watts of power.
The POE21-240 application field and working principle are two important elements to understand the effectiveness of this protocol. POE21-240 has many application fields, such as telecommunication, security and surveillance, networking, industrial control, and home automation. For example, in telecommunications, POE21-240 can be used to power phones, VoIP phones, PBX, PoE switches, and other such devices. In security and surveillance, POE21-240 is used to power surveillance cameras, Wi-Fi access points, and signaling systems. In networking, POE21-240 is used to power network-attached storage systems, servers, routers, and switches. In industrial control, POE21-240 is used to power sensors, actuators, and industrial controllers. In home automation, POE21-240 is used to power lighting, HVAC systems, and home security systems.
The POE21-240 protocol works by utilizing the unused pairs of copper wire in a regular Ethernet cable to deliver power to connected devices. This allows the use of a single cable to provide both data and power. Typically, the cable will be used as a normal Category 5 (Cat5) or Category 6 (Cat6) cable, with one pair used for data and the other two pairs for power. The POE21-240 protocol is designed to ensure the safety and reliability of the power delivery. It supports two modes of operation, Class 0 and Class 1. In Class 0 mode, the power delivery is limited to 15.4 Watts, while in Class 1 mode the power delivery is increased to 48 Watts. For devices that require more than 48 Watts of power, such as access points, PoE switches, and PDUs, the POE21-240 standard provides additional support for a PoE output of up to 240 Watts.
In order for a system to properly detect and utilize the power delivered by a POE21-240-compatible device, it must be able to interpret the signaling voltage 4-pairs of wires. The POE21-240 standard defines a minimum signaling voltage of 20-30 volts for Class 0 and up to 44-57 volts for Class 1. In order for an electrically powered device to recognize and use power from POE21-240, it must implement support for POE21-240. Generally, this is done by employing the usage of PDU in which can monitor and detect the power from POE21-240. PDU also has a feature that prevents short circuit when handling the power from POE21-240.
Overall, the POE21-240 standard provides a cost-effective and highly dependable solution for powering powered devices such as IP phones, wireless access points, and IP cameras without the need for a dedicated power connection. The standard is versatile and can be used in a wide variety of applications, from telecommunication to home automation. The POE21-240 protocol utilizes standard Ethernet cable to deliver power to connected devices, while the use of PDU can ensure the safety and reliability of the power delivery. As such, the POE21-240 standard is an important technology that is helping to power the connected world.
