Phihong POE21u-1AF Single Port Mid-Span PoE Injector

[[start tab]] Description This 60W 56V Gigabit PoE Injector (Power over Ethernet) is a single port IEEE 802.3 AF/AT/BT(type 3) compliant midspan solution that is a compact and easy to install with RJ-45 Ethernet cabling. This elegant unit is ideal for installing any Novanex clock or OAX2 messaging sign. It eliminates the need for external power supply and its associated AC/DC power cabling, providing a compact, affordable, safe and reliable power solution over your wiring or existing Ethernet infrastructure. The Gigabit PoE Injector is very lightweight and compact. It is an 802.3 AF/AT/BT compliant device, and uses all 4 pairs in a category rated wiring bundle, i.e. CAT5e (or better) run required for Gigabit Ethernet.  It supports both 2-pair and 4-pair PoE outputs, and is ideal for installing Novanex IP PoE devices. PoE voltage drops over distance. As a rule of thumb you can lose up to 6V per every 100′- 200′ of wiring, depending on the gauge. Lower power also means more amperage mean
