The POE-PT151 is an IEEE 802.3af Power over Ethernet Injector that provides DC 48V over Ethernet cables. The POE-151 IEEE 802.3af Power over Ethernet Injector inserts DC voltage into Cat.5 cable, allowing the cable between the Injector (POE-PT151) and Splitter (POE-PT151S or POE-PT152S) to transfer data and power simultaneously. The maximum distance between the Injector and Splitter is 100 meters. With POE-151 being installed, it combines the Ethernet digital data with power over the twisted pair cables as an IEEE 802.3af Power over Ethernet Injector. And the IEEE 802.3af Power over Ethernet splitter will split the digital data and the power into two outputs.With IEEE 802.3af Power over Ethernet devices being installed, the system administrator only has to use a single RJ-45 Ethernet cable to carry both power and data to each device. Besides, when used with the POE-PT151S or POE-PT152S, the POE-PT151 can offer the benefits of cost saving, easy networking planning and higher reliability. What’s more, upon any IEEE 802.3af devices being installed, the POE-PT151 or together with POE-PT151S/POE-PT152S can make the connection while migrating or splitting the power and the Ethernet digital packets, such as connecting the POE-PT151 to an IEEE 802.3af complied device, AP or IP phone.
