Power over Ethernet (PoE) is a technology used to transmit power from one device to another over Ethernet cables. PoE is used to enable devices that would otherwise require an external power supply to be powered directly by a PoE-capable device. POE480U-4UP is one of these PoE-capable devices. It is a switch that provides 48V DC power to up to 4 devices simultaneously. In this article, we will discuss the application field and working principle of the POE480U-4UP.

Application Field of POE480U-4UP

The POE480U-4UP is suitable for many applications. It is often used in medical and automotive fields, especially when providing power for low-voltage devices, such as cameras, lighting systems, display screens, and printers. In addition, it can also be used in smart home systems, telecom networks, industrial control and monitoring systems, and access control systems. The POE480U-4UP can be used to power 4 devices with a maximum load of 15.4W each, which is enough to power most low-power devices.

Working Principle of POE480U-4UP

The POE480U-4UP works by using the Ethernet cables to transmit power from the PoE-capable device to the powered device. The device uses the Data and Power over Ethernet (DPoE) protocol to ensure that the power is transmitted safely. The device also uses the Power Distribution Data (PD-Data) protocol, which is derived from the IEEE 802.3af standard. This protocol is responsible for powering the device and setting the correct voltage. It also offers protection against short circuits and overvoltage.

The PoE480U-4UP also uses Automatic Device Detection (ADD) in order to detect the power requirements of the device that it is powering. When the device is plugged in, the PoE480U-4UP will detect the power requirements of the device and adjust its output voltage accordingly. This ensures that the device is powered correctly and there is no risk of damage from incorrect voltage.

The POE480U-4UP also includes features such as overload protection and temperature monitoring. The device has built-in temperature sensors that can detect any overheating and will shut down the power if the temperature exceeds a certain threshold. This ensures that the device is safe and prevents any damage from occurring.

Conclusion

The POE480U-4UP is a powerful and reliable power-over-Ethernet switch. It is suitable for a variety of applications and is easy to install and use. It offers protection against short circuits and overvoltage, and ensures that the device is powered correctly. It also offers temperature monitoring and overload protection. The POE480U-4UP is a great choice for powering low-voltage devices.
