WHAT IS POE AND HOW IS IT DIFFERENT?
PoE lighting uses Power over Ethernet technology to connect, monitor, and control LED light fixtures – typically used in Smart Building solutions. Figure 13 illustrates a typical PoE system.
PoE systems provide low-voltage (less than 100W), direct current (DC) electrical power to network devices via the same twisted-pair copper Ethernet cables that are used to for data transmission. This removes the need for a separate AC power source and thus allows for more placement options without the need to provide a power outlet.
The major components needed are a PoE switch (Cisco, Ubiquiti, Netgear, etc.), a PoE server/gateway, the Poe Software, located on the PoE server and wiring. Most PoE platforms use standard CAT5/6 cable.
Contrast this to a typical Class 2 DC Distributive Lighting system architecture as shown in Figure 14 below:
Since communication to each fixture is not needed, the system architecture is greatly simplified. There is no need for the expensive hardware and software that is required for PoE systems. Additionally, the CLEANLIFE 24VDC Class 2 driver can be conveniently installed in multiple locations such as in a closet, media enclosure (see Figure 15), a utility room or in a wall behind an access panel, where they are out of the way, yet serviceable if needed. To further simplify the system, the drivers do not need to all be in one location but could be distributed throughout the home in various convenient locations. This can save time and cost by reducing the required length of the cable runs.
