Power over Ethernet (PoE) is a technology that enables an electrical connection to be established over an ethernet cable. This technology has enabled the use of low cost, low power peripherals, such as wireless networking equipment, IP cameras and access points, for increased scope and versatility in the deployment of network-connected devices in areas which were previously unreachable. The PD69200X-GGGG is a Power over Ethernet Controllers which are designed to enable the deployment of PoE applications in high-density, multi-port implementations.

Power Over Ethernet (PoE) Principles

In order to understand the application field and working principles of the PD69200X-GGGG, it is necessary to understand the fundamentals of Power over Ethernet. Power over Ethernet is a technology which uses the 4 pair wiring of an Ethernet cable to transmit both power and data between two devices, such as an End-User Device (EUD) and a PoE switch or midspan. The EUD is the device that requires power from the PoE supply, while the switch or midspan is responsible for providing the electrical power.

In order to ensure the safe transmission of power over the Ethernet cable, PoE relies on specific technologies. One of these is the Power Source Equipment (PSE), which is either integrated into the switch or supplied by a midspan. The other is the Powered Device (PD), which is the endpoint device that utilises the power provided by the PSE. To enable power transmission, the PSE and PD must be compatible and use the same PoE standard.

PD69200X-GGGG Power Over Ethernet Applications

The PD69200X-GGGG is a high-speed, multi-port controller designed for applications that require the deployment of both Power over Ethernet (PoE) and data over an Ethernet cable. It is designed for applications using Ethernet cables up to lengths of 100m and can handle up to 16 PoE ports, with power output of up to 25.5W per port. The controller features multiple protocols for communication, including Power Delivery (PD), Link Layer Discovery Protocol (LLDP) and 802.3bz-2.5G/5G Base-T.

The PD69200X-GGGG is an efficient and cost-effective solution for high-density PoE plus data applications and is suitable for a wide range of industries, including automotive, industrial, telecom, and medical applications. It is an excellent choice for installing PoE-enabled devices in areas where there is limited access to power, such as in remote locations, or in enclosed environments.

Working Principles of the PD69200X-GGGG

The PD69200X-GGGG is an intelligent power-management unit, as it features both a controller and a power supply. The controller is responsible for managing the power delivery, which is why it is referred to as a “controller.” It works in conjunction with the power supply, which is responsible for supplying the power to the PD69200X-GGGG-enabled PDs. The controller is capable of detecting PDs, initiating link-layer discovery, and automatically exchanging power and data. The controller also features protection from overload and surge events, as well as advanced power-management features, such as the ability to switch ports between on and off states, or sleep and wake modes.

The controller also features advanced control systems, such as the monitoring of temperature, current and voltage, which can be adjusted as needed, in order to maximize the efficiency of the power delivery to the PDs.

Conclusion

The PD69200X-GGGG is an advanced Power over Ethernet Controller designed for high-density PoE applications. It enables the deployment of PoE devices in areas with limited access to power, while providing advanced power management features that ensure a safe and efficient power delivery to the PDs. The PD69200X-GGGG is a cost-effective solution for a wide range of PoE applications, in industries such as automotive, industrial, telecom, and medical.
