Power over Ethernet (PoE) technology is an emerging technology allowing devices to be powered over Ethernet data cables. POE14-120 is one of the standards used in the Power over Ethernet technology. POE14-120 is designed for high current applications such as CCTV cameras, Wi-Fi access points and LED lighting. This article will discuss the application field and working principle of POE14-120.

The POE14-120 power supply specification is used to power devices that require larger amounts of power than what the POE10-100 specification can provide. POE14-120 provides up to 30W of power per connection and is best suited for devices that require higher power such as CCTV cameras, Wi-Fi access points and LED lighting. The voltage range of POE14-120 is adjustable from 14V up to 120V.

As far as applications go, the main uses of POE14-120 are to power network connected such as CCTV cameras, Wi-Fi access points and LED lighting. CCTV cameras benefit from POE14-120 because the power supply for the camera is distributed through the data cable, making installation and setup of the camera much simpler. Wi-Fi access points also benefit from POE14-120 because the multiple-input/multiple-output (MIMO) antenna configuration can require more power than what is available from the POE10-100 standard. Finally, LED lighting which can also require more power than the POE10-100 specification can offer, will benefit from POE14-120.

The working principle of POE14-120 is based on the IEEE 802.3af and 802.3at. The 802.3af and 802.3at standards regulate the voltage and power and is the basis for POE14-120. In the 802.3at standard, a powered device is required to conform to the standard to ensure compatibility. The standard specifies a DC power output voltage of 48V. The power supply of POE14-120 is based on the 48V DC voltage but with adjustable range up to 120V DC.

The voltage is regulated by the POE14-120 power supply which converts the 48V DC into a 14 – 120V DC output voltage. The voltage is regulated by the controller board. The power supply board provides isolation between the power input and the power output. The power is transmitted through CAT-5e cabling and is detected through the RJ-45 connector of the device to be powered. IF the device is compatible and the power is detected, then the power is transmitted through the CAT-5e cable.

In conclusion, POE14-120 is a power supply specification designed for high current applications such as CCTV cameras, Wi-Fi access points and LED lighting. The voltage range of POE14-120 is adjustable from 14V up to 120V. This allows the device to be powered with the correct amount of power. The working principle of POE14-120 is based on the IEEE 802.3af and 802.3at standards and is regulated by the controller board and power supply board.
