• 7 Ports Gigabit Switch With 4Ports PoE
• It accepts the input voltage as low as 12VDC, to be boost up to 55VDC
• Operating Temperature -40℃~75℃ fully tested.
• Equipped with high efficiency ColdDesign technology capability
This Super Voltage Booster --- The high power 4 port industrial POE+ Injector is equipped with our high efficiency ColdDesign technology which allows low input voltage, such as 12/24/48VDC be boost up to 55VDC to meet IEEE802.3at requirement. The ColdDesign technology will not only boost up Input Voltage, also reduce the excessive heat problem to a minimum. It accepts the input voltage as low as 12VDC, to be boost up to 55VDC. And it is also equipped with 2 port SFP fiber 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.
