<p>It does not have auto detection function and directly supply power to devices by force as soon as you connect them,powered device or poe splitter must conform to standard IEEE 802.3af\/at,the same time your powered device must support poe pin 4\/5(+),7\/8(-)midspan.</p> <p>Power Input = Power Output*channels,Take 4Port POE,injector as example:DC48V 4A Input = DC12 V1A Output per channel,DC48V 2A Input = DC48V 0.5A output per channel.If you only use 3 of 4 channels,DC12V3 A input = DC12V 1A output per channel.</p> <p>Please select according your device power consumption,in order to stable running,the total power consumption must be lower than the total power supply.This POE adapter apply for IEEE802.3af\/at standard POE powered devices like , and other IP cameras,or being equipped together with IEEE802.3af\/802.3at standard poe splitter for non POE devices.</p> <p>Led:Indicate the working state,Lan port:8ports in RJ45(data in),8port poe RJ45(data\u0026power out),Data in:PC\/Hub\/Switch\/Router,etc.Working temp:0~+40 Celsius.Working humidity:20 ~90% RH non-condensing,Storage temp \u0026 humidity:-20~+85 Celsius,10~95% RH,weight:120g</p> <p>Colour:Black </p> <p>Material:ABS + electronic components</p> <p>Product size:10*4.7*3.1cm</p> <p>Package Contents:</p> <p>1 * 4 port POE hub</p> <p>1 * carton</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
