VONETS VSP510 5 Ports Ethernet Gigabit Switch with DC Adapter + Rail Fixing Buckle Set 1. Industrial Ethernet switches are specially designed for reliable and stable operation in harsh industrial environments. 2. Supports IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE802.3ab, IEEE 802.3z, IEEE 802.3af, IEEE 802.3at protocols, Gigabit SFP port (optical module) and 101001000Mbps RJ45 port, all DuplexHalf-duplex. 3. Supports DC12V~DC48V wide power input, and POE output is only effective when the power input is 48V (greater than or equal to 96W). 4. The one-piece thickened aluminum alloy shell is more conducive to use in harsh industrial environments, with fast heat dissipation and durability. 5. The use of industrial-grade temperature compensation devices helps the switch maintain a long-lasting and stable communication rate. 6. Can be easily installed on the DIN rail and in the distribution box. DIN rail mounting and metal housing with LED indicators make the switch plug-and-play simple and reliable. 7. Working temperature: -40 degrees Celsius to +55 degrees Celsius 8. Power input: DC 12V-48V 9. Load overcurrent protection: less than 3A 10. Non-POE input power: 10W 11. With POE input power: 10W+90W 12. Input overvoltage protection: less than 54V-59V 13. Input reverse connection protection (reverse voltage): less than 54V
