802.3at PoE Input to 802.3af and Passive PoE Outputs, Active Splitter (POE-SPLT-48G-VUB)



The POE-SPLT-48G-VUB is an active splitter which accepts an 802.3at Mode A/B or passive PoE (2 or 4 pair) input and provides two PoE outputs. Output 1 is an 802.3af Mode B PoE output with Data and PoE. Output 2 is a 48V Passive PoE Mode B output with PoE only, no data. The splitter is designed to supply power and data to one device and power only to the second device. It is Gigabit compatible providing speeds to 1000MB. There are various protections for short circuit, overload and low voltage disconnect.
