This industrial 5 port gigabit PoE switch ( 4-port PoE) features 30W of power and is designed to be installed in harsh environments and supports up to a total of 120W power outputs. For Demanding Environments Where No Fiber Connections Are Required Using Cat 5e (or higher rated) Ethernet cabling, this Ethernet switch Provides up to 30W of PSE power per PoE port (PSE) to IEEE 802.3af (PoE / Type 1) and IEEE 802.3at (PoE+ / Type 2) PD devices like: Cameras Sensors Wi-Fi Access Points High total power budget with high PoE port count at a maximum of 30 watts per port, up to 120 watts max. Power provided in order of device connection; max four 802.3at (30W) devices (120W total) at any time. Truly Industrial for Devices That Must Function Under Harsh Conditions Industrial features include: Operating Temperature Range: -40 C to 75 C IP-30 rated housing Vibration, shock, and free-fall standard testing This Ethernet switch supports additional features such as redundant power inputs, 2kV surge protection on RJ45 ports, and an MTBF of 600,000+ hrs (Telcordia/Bellcore ) at 50°C, for long-term reliability. A Flexible & Easy-to-Deploy Solution Includes hardware for DIN rail or wall mounting, right out of the box. The unique barrel power adapter allows for standard wall adapters to be used instead of being hardwired and the alarm relay can be integrated into any solution.
