Power over Ethernet (PoE) is a technology that enables network devices such as switches, routers, access points, VoIP phones, and surveillance cameras to be powered by electricity that is transmitted over standard Ethernet cabling. PoE eliminates the need for external power supplies and reduces the cost and complexity associated with providing power to network devices. POE21W-1AF is the latest advancement in PoE technology and is designed to deliver up to 30 watts of power over a single Ethernet cable.

The POE21W-1AF provides 30 watts of power across four twisted-pair cables using a four-pair, differential-mode, transmission technique and is backward compatible with existing two-pair PoE systems. This allows the device to be used for a wide range of applications, from powering small devices such as IP phones and access points, to larger devices such as thin clients and ultrasound equipment. The POE21W-1AF is also compatible with all IEEE 802.3af and IEEE 802.3at compliant Power over Ethernet (PoE) devices and can be used in any environment where PoE is used.

The POE21W-1AF is designed to support a wide range of applications in any type of environment. It is equipped with multiple safety features, including overvoltage, over current,short-circuit, and reverse polarity protection. Additionally, the device supports a wide range of operating temperatures and is protected from power spikes and surges. The POE21W-1AF also features a self-healing feature that allows the device to automatically reset itself in the event of a power failure.

The POE21W-1AF is designed to be easy to install and configure. It is equipped with two power pins for connecting to the power input and two data pins for connecting to the Ethernet network. The device also features an autonegotiation mode, so that it can automatically detect the speed and type of cabling being used. The device can also be configured using the included management software, which allows administrators to adjust the power levels, monitor power consumption, and set alarms.

The working principle of the POE21W-1AF is based on the IEEE 802.3af and IEEE 802.3at standards. The device works by sending a DC voltage over the four pairs of the twisted-pair cables in such a way that each cable transmits a different voltage than the other three. This allows for the device to deliver a stable current of up to 30 watts over a single cable. The POE21W-1AF also includes a controller, which performs voltage and current detection and monitoring of the cable to ensure that the device is functioning as intended.

The POE21W-1AF is a versatile and cost-effective solution for powering network devices in any environment where PoE is used. It is designed to deliver up to 30 watts of power over a single cable and is backward compatible with existing two-pair PoE systems. The device is equipped with multiple safety features, is designed to be easy to install and setup, and includes a self-healing feature that allows the device to automatically reset itself in the event of a power failure. The POE21W-1AF is the perfect solution for powering any type of network device in any type of environment.
