Phihong 33.6W Power over Ethernet Single Port Midspan IP67 Waterproof Power Injector - POE33U-1AT

33.6W Power over Ethernet single port IP67 midspan waterproof power injector with IEEE802.3at compliance for use with outdoor equipment such as security cameras with pan/tilt/zoom, outdoor wireless access points and outdoor emergency lighting in residential, commercial and industrial applications. The 33.6W at 56V output of this Power over Ethernet single port midspan power injector compensates for up to 7.65W in wire drops to devices that are up to 100m away from the network switch which is ideal for users wanting to expand their security or wireless networks. This Power over Ethernet midspan waterproof power Injector has a wide operating temperature range of -40 to +60°C, an efficiency of 70% typically and can also operate at gigabit Base-T data rates. The three ports on the front of the power injector unit accommodate standard 3/4 NPT waterproof/watertight conduit and or cable glands. The unit has a non-vented case with a mounting bracket.

Spare Pair and Data Pair powering - ULTRA Power midspans stk nos. 666-8211 (POE60U single-port) and 666-8220 (POE80U single-port), have a combination of Spare Pair and Data Pair powering over the full 8 wires. There are no specific IEEE standards for these yet. The midspans are compliant to the performance of 10baseT, 100baseT and 1000baseT (Gigabit). They have safety features, such as handshake detection, overload, connect and disconnect functionality as for the IEEE802.3af and IEEE802.3at standards but the handshake detection resistance is 12.5KΩ, instead of 25KΩ for the IEEE802.3af and IEEE802.3at standards
