NCP1090DRG

Power Over Ethernet (PoE) Controllers

Power Over Ethernet (PoE) controllers are devices that provide power to Ethernet-enabled devices, using the same cable used to transmit data. PoE controllers, like the NCP1090DRG, allow for faster deployment and increased flexibility in settings where the device is not located near an AC outlet or in an area that does not have access to AC power.

NCP1090DRG Application Field

The NCP1090DRG is a PoE adapted controller that allows to delivery of power across Ethernet cables, while still providing the ability to transmit data. It supports Power over Ethernet (PoE) at power levels up to 15.4 W, making it ideal for a variety of applications such as IP phones, VoIP adapters and surveillance systems. It is designed to allow the connection of several Ethernet-enabled devices at once, providing the ability to power several devices at once, thus reducing installation and maintenance costs.

NCP1090DRG Working Principle

The NCP1090DRG follows the IEEE 802.3af standard, using a proprietary Ethernet packet structure to detect and disconnect devices requesting more current than allowed by the PoE specification. The Ethernet packet follows the sequence S--D--S--D--S to detect the signature of a powered device. During the first D--S sequence the Mac address of the device is ascertained using the IEEE standardized message exchange. Using this information the NCP1090DRG assesses the power needs of the device, and if needed/available, allocates the adequate amount of power in the range of 0.44 W to 15.4 W.

The NCP1090DRG ensures maximization of power delivery, detecting the amount of power needed by the device and controlling the output of power accordingly. It also reduces the Overvoltage Protection (OVP) trigger levels, providing a cost effective solution for PoE applications. In addition, the NCP1090DRG comes with a Battery Backup Control (BBC) system, allowing it to reverse the roles between the power supply and the device in case of an outage, delivering the power from the device to the power source via an Ethernet cable.

NCP1090DRG Benefits

The NCP1090DRG offers an efficient, simple and safe solution for power over Ethernet applications, allowing for easy and fast installation and maintenance. It also provides increased safety, as it eliminates the need for additional wiring and cabling, thus saving time and cost. Additionally, it uses advanced power saving techniques to significantly reduce the power consumption of the device, thus increasing the efficiency and power savings. In addition, it is compliant with the IEEE 802.3af PoE standard, making it suitable for a variety of applications.

Conclusion

The NCP1090DRG is a reliable, efficient and safe solution for powering Ethernet-enabled devices. It provides increased safety and flexibility, eliminating the need for extra wiring and cabling, and reduces power consumption, making it ideal for a variety of applications such as IP phones, VoIP adapters and surveillance systems. Additionally, it is compliant with the IEEE 802.3af PoE standard, making it suitable for a variety of applications. In conclusion, the NCP1090DRG is an ideal solution for Power Over Ethernet needs.
