POE (Power Over Ethernet)Refers to the existing EthernetCat.5Cabling infrastructure do not make any alteration in the case , based on the number ofIPA terminal ( such asIPTelephones, wireless LAN access pointsAP, Network cameras , etc. ) transmit data signals at the same time , but also for providing DC power supply such equipment technology.
POEThe principle of supply through the cable
Standard UTP cable has four twisted pairs,However, inl0M BASE-TAnd100M BASE-TUses only one of the two pair.IEEE80 2.3afAllows two kinds of usage,When the application is idle foot-powered, 4,5Pin connector for the positive7,8Pin connector is negative. Application data when powered foot,WillDCIncrease in the transmission power transformer midpoint,Does not affect the data transmission . In this way right off the assembly line1,2And wire3,6Can be of either polarity . Standard does not allow application of the above two cases simultaneously . Power supply equipmentPSEOffer only one usage,But the power application equipmentPDMust be able to accommodate both cases .
POEBenefits of power supply :1It cost savings. Because it only needs to install a cable instead of two . In many cases , difficult to deploy to be installed in place of the AC power . With the device connected to the Ethernet increases if do not need to provide local power equipment , will greatly reduce the cost of deployment and simplify manageability.2It is easy to install and manage . Customers can automatically and safely mix legacy devices on the network andPoEApparatus capable of coexistence with the existing Ethernet cable .3, It is safe . BecausePoESupply terminal equipment powered devices will only need to supply. Only powered device is connected to the Ethernet cable will have a voltage is present , thereby eliminating the risk of leakage current on the line .4, It is easy to manage network devices .
Features:Single-port network remote power supply has the following excellent properties :1 .Power supply with input over- voltage, output over -voltage, output over-current and short circuit protection .2Ethernet port speed:10M/100Mbps;3 .Conducted interference (CE), compliant with IEEE802.3af Power over Ethernet standard .4 .Lightning Features: AC input , can withstand5KB,8/20uSThe impact of current waveforms, plus or minus5Times between1Minutes ; lightning protection circuit failure alarm function and insurance management and other security components.
Operating environment:1 .Temperature :-10 ° -50 °;2 .Relative humidity:5%~90% RH; 3.Ventilation , clean, non-conductive dust , corrosive gases ;4 .No explosion hazard
Technical characteristics and parameters:1 .Input voltage:165VAC~280VAC,47Hz~63Hz.2 .Maximum power output :12W: 3.Output voltage accuracy :-12VDC ± 2% 4.Load Regulation:-12VDC ± 1%; 5.Operating ambient temperature range :-10 ° ~ 50°;6 .Broadband noise DC output voltage:3.4kHz~150kHz ≤ 50mv
Power indicator:Indicator light : Indicates that the power is working properly , the normal power supply.LED OFF : Indicates that the power does not work.Power during normal operation , insert the output lines , the light is off when overload or short circuit protection ; possible high power electrical equipment , cable short circuit or electrical equipment damage.
