Description
This rugged designed high power 4 port industrial POE+ Injector is equipped with our high efficiency ColdDesign technology which accept input voltage from 44-56VDC to meet IEEE802.3af/at standard, and to reduce the excessive heat problem to a minimum. It is equipped with 4 port 10/100M TX PSE to power up PD device and to provide power 15.4Watts for IEEE802.3af or 30Watts (Max 36W) for IEEE802.3at per port . With our optional models with Fiber uplinks, that can be used as fiber redundancy, cascaded to your other devices to expand your network application. It is being rigorously tested for your Security, Transportation and Telco application.
