48V PASSIVE POE ADAPTER

provides power using all four pairs of a twisted-pair cable. This enables higher power for applications like pan–tilt–zoom cameras (PTZ), high-performance WAPs, or even charging laptop batteries.

In mode B, pins 4–5 (pair #1 in both T568A and T568B) form one side of the DC supply and pins 7–8 (pair #4 in both T568A and T568B) provide the return; these are the "spare" pairs in 10BASE-T and 100BASE-TX. Mode B, therefore, requires a 4-pair cable. PoE Splitters that output the power, often at a different voltage (e.g. 5V), to power a remote device or charge a mobile phone

Minimal investment budget: Utilizing the existing Ethernet equipment and cabling infrastructure, the relevant costs will be minimized in a PoE injector solution.

How do you install a PoE injector?

Versa Technology has a line of high-quality PoE injectors that will enable you to couple non-PoE power sourcing equipment (PSE) with PoE PDs. We will not sell, distribute or lease your personal information to third parties unless we have your permission or are required to do so by law Mount the IP camera where there is adequate light to ensure it can capture a clear image on the screen. Most switched-mode power supplies within the powered device will lose another 10 to 25% of the available power to heat. PoE port power supply – PoE vs PoE+ vs PoE++: Make sure your injector's PoE standard is compliant with your PDs. There are three main PoE standards—802.3af (PoE), 802.3at (PoE+), 802.3bt (PoE++). They support a power supply of up to 15.4 W, up to 30 W, and up to 60 W /100 W respectively.

The integration of PoE with the IEEE 802.3az Energy-Efficient Ethernet (EEE) standard potentially produces additional energy savings. Pre-standard integrations of EEE and PoE (such as Marvell's EEPoE outlined in a May 2011 white paper) claim to achieve a savings upwards of 3W per link. This saving is especially significant as higher power devices come online.

A distinction is made between two scenarios: To retain power, the PD must use at least 5–10mA for at least 60ms at a time. If the PD goes more than 400ms without meeting this requirement, the PSE will consider the device disconnected and, for safety reasons, remove power. [35] Advocates of PoE expect PoE to become a global long term DC power cabling standard and replace a multiplicity of individual AC adapters, which cannot be easily centrally managed. [22] Critics of this approach argue that PoE is inherently less efficient than AC power due to the lower voltage, and this is made worse by the thin conductors of Ethernet. Advocates of PoE, like the Ethernet Alliance, point out that quoted losses are for worst case scenarios in terms of cable quality, length and power consumption by powered devices. [23] In any case, where the central PoE supply replaces several dedicated AC circuits, transformers and inverters, the power loss in cabling can be justifiable.
