STEAMEMO AI PoE Switch, 52V 52W (4 POE Ports +2 Uplink) 100Mbps,802.3af/at, Unmanaged Network Extender Power Over Ethernet for IP, Extend Function,Metal Plug and Play

Active poe switch with 802.3 af/at compliantSTEAMEMO poe switches support poe devices and non-poe devices, But when connecting passive poe device or non-poe device, the switch can only transmit data and cannot power your device, so the connected device needs to be separately powered. Or you can use it with active poe splitter.
4 port poe switch*100M@52W PoE switch with 4 port PoE + 2 Uplink port, 4× PoE ports providing up to 30W per port, total PoE budget 52W, 2 port uplink ideal for connecting NVR and Internet, etc.
4KV Lightning ProtectionSTEAMEMO PoE switch have professional lightning protection design-up 4KV port and power supply thunder prevents, with two levels of protection design respectively, effectively restrain the power of lightning from cable, which equivalent to give the entire network monitoring system with a security fence.
AI Watchdog function of poe portWhen the data or electrical transmission between the poe port and the terminal device is abnormal, the corresponding poe port of the device will automatically detect the problem and restart the connection.
AI 250 meters Extend functionTurn on the extension switchit enters the AI modePOE port will judge whether it enters the ultra-long distance (820ft/10Mbps) mode according to the actual situation). Extend function extending max power and data transmission distance from 100 meters (330ft) to 250 meters (820ft). which is easy to expand network via ethernet cable to somewhere without power supply but need fix device such as IP Cameras.
AI PD DetectionThe poe port will intelligently judge whether the device connected to the port needs power supply. If it is a non-poe device that does not need power supply, the switch will not supply power to these devices and will not damage the device.
Network cable short-circuit protection mechanismSTEAMEMO POE switch is stable and has strong anti-interference ability, protect the fault caused by the short circuit of the network port. Short Circuit, Over Current and Over Voltage Protection.
