Functions: Made of plastic, sturdy and durable to use. They comply with international safety standards and are safe to use. This custom passive PoE injector is a simple and convenient device for PoE or Non PoE devices via Ethernet cable. This PoE injector is compatible with IEEE802.3af/at network devices. Apply for IEEE802.3af/in standard POE powered devices such as DAHUA, HIKVISION and other IP cameras, or equipped together with IEEE802.3af/802.3at standard PoE splitter for non-POE devices. There is no automatic detection function and directly powers network devices by force as soon as you connect them, the powered device or PoE splitter must comply with IEEE 802.3af/at standard, at the same time your powered device must support Poe Pin 4/5 (and), 7/8(-) midspan connector. Technical data: Voltage: DC12V-48V (up to 10A) Led: indicates the working status Power Pin: 4 5 (and), 7 8 (-); Data Pin: 1236 LAN port: 8 ports in RJ45 (data input), 8 ports poe RJ45 (data power output) LAN environment: 10/100 Mbps Base-T, Ethernet cable: TIA/EIA 568 cat. 5 or cat. 5e Data in: PC / Hub / Switch / Router etc. Operating temperature: 0-and40°C Operating Humidity: 20-90% RH non-condensing Storage temperature humidity: -20-and85°C, relative humidity 10-95% Size: 10 cm x 4,7 cm x 3,1 cm / 3,9 x 1,9 x 1,2 inch Package Weight: 98 g / 3,5 oz 1. Choose the power consumption of the device accordingly to ensure stable operation, the total power consumption must be lower than the total power supply. 2. Tip: the supply voltage should not exceed 48 V DC.
