Univerzální pasivní POE injektor pro vzdálené napájení aktivních prvků s integrovaným extraktorem po UTP kabeláži. Osazen LED indikátorem pro snadnou vizuální kontrolu provozu.
Spec Passive POE (Power Over Ethernet) adapter, uses unused pairs of 100baseT network cable to transmit power to remote device.
Pinout DC jack center positive, 2.1 mm pin. RJ45 pins 4,5 = positive, RJ45 pins 7,8 = negative.
Issues Passive POE does not comply with the IEEE 802.3af specification.
To minimize cable losses, feed the highest allowed voltage, e.g. 18V. Demarc Technology has a nice POE voltage drop calculator. Keep in mind that WRAP input power is fairly constant over input voltage - when the input voltage drops, the current goes up. Power = voltage * current.
To avoid ground loops, ground should be referenced on the receiving end only, that is use a 2 prong (non grounded) AC adapter.
