Introduction

Power over Ethernet (PoE) Controllers are devices that are designed to provide power to remote endpoints without the need of an additional power source. By utilizing standard Ethernet cabling, PoE Controllers are able to deliver power to PoE compatible endpoints such as IP cameras, IP phones, access control devices, and wireless access points. NCR1082DER2G is a popular PoE controller that is capable of providing power to up to 2 Gigabit Ethernet ports simultaneously.

NCR1082DER2G Application Field and Working Principle

NCR1082DER2G is a single port IEEE802.3af/at compliant PoE controller. It features a maximum output current of 2A @ 54V, and allows for power sourcing up to 2 Gigabit Ethernet ports simultaneously. The NCR1082DER2G\'s working principle is based on the voltage or current that it receives from the PD (Power Device). This voltage enables it to determine the type of PD (Type I or Type II) so that it can deliver the correct amount of power to thePD required.In Type I systems NCR1082DER2G acts as a source of power and the PD (Power Device) is the load. The controller provides the voltage to the PD and the load is then determined by the PD. In Type II systems the controller acts as a load and the PD is the source of power. The PD provides the voltage and current to the controller and the controller then provides the correct amount of current/voltage to the PD.The NCR1082DER2G is typically used in applications such as VoIP phones, IP Cameras, access control devices, and wireless access points. It is a popular choice for these applications as it is reliable, cost-effective and easy to set up. The controller also supports up to 2 Gigabit Ethernet ports, making it suitable for applications with high speed data transmission requirements.

Conclusion

The NCR1082DER2G is a highly reliable and cost-effective PoE controller that can provide power to up to two Gigabit Ethernet ports simultaneously. It is typically used in applications such as VoIP phones, IP Cameras, access control devices and wireless access points. The controller is capable of providing power in both Type I and Type II systems and its working principle is based on the voltage or current that it receives from the PD (Power Device). As such, it is well suited to applications that require a reliable and cost-effective solution for providing power over Ethernet cabling.
