UTP28CH3.5M is a kind of new product which is widely used in many fields. It is a Power Over Ethernet (PoE) Controller which is based on IEEE 802.3af-2003. The controller has 28 output ports with power output of 3.5W per port. It is also suitable for Power Sourcing Equipment (PSE) applications. UTP28CH3.5M is a feature-rich PoE controller, providing unique features for various applications. This article will discuss the application field and working principle of UTP28CH3.5M.

Application Fields of UTP28CH3.5M

UTP28CH3.5M can be used in many fields, including CCTV and access control systems, as well as communication networks and HVAC systems. UTP28CH3.5M supports up to 28 channels of PoE power, so it is suitable for multiple cameras in a surveillance system or multiple access control gates in a door system. Moreover, the low power output of 3.5W per port allows for direct powering of most PoE-enabled security cameras and door controllers without the need for additional power supplies. In addition, UTP28CH3.5M can also be used in computer networks, providing power and data over Ethernet cables.

Working Principle of UTP28CH3.5M

UTP28CH3.5M is a fully featured PoE controller which is compliant with IEEE 802.3af-2003. It supports up to 28 channels of PoE power, with output power of 3.5W per port. The controller utilizes the Advanced Encryption Standard (AES) for secure data transmission and supports up to 4-pair Ethernet cables. Furthermore, it provides galvanic isolation of up to 1.2kV, allowing it to protect any external ports from voltage and current surges.

In order to provide power and data to connected devices, the PoE controller must first detect and classify the attached PoE devices. This is done by sending Remote Management Interface (RMI) frames to attached devices, which contain the device’s classification information. UTP28CH3.5M is equipped with an Autonomous Detection option, which allows the PoE controller to automatically adjust its power output profiles according to the device’s power requirements, assuring maximum power delivery efficiency.Once the PoE devices are classified, UTP28CH3.5M will automatically detect and apply the required power output, delivering up to 3.5W per port. In order to guarantee a reliable and safe power delivery to PoE devices, the controller implements a comprehensive suite of safety measure, such as short-circuit protection, over-voltage protection, and over-current protection.

UTP28CH3.5M is an efficient and feature-rich PoE controller, which can be used in many applications. It is compliant with IEEE 802.3af-2003 and supports up to 28 channels of PoE power, with output of 3.5W per port. Furthermore, it utilizes the Advanced Encryption Standard (AES) for secure data communication and provides industry-leading safety features, ensuring maximum reliability and protection of attached devices.
