SEL-2725 Таван порттой Ethernet шилжүүлэгч

he SEL-2725 is an unmanaged five-port switch and copper-to-fiber-optic media converter. Apply to build reliable, safe Ethernet networks in electrical substations, plants, and other mission-critical sites. Connect to devices in the same cabinet using shielded twisted-pair Category 5 cable, and communicate with the substation or plant local-area network (LAN) with a fiber-optic link.


Withstands vibration, electrical surges, electrostatic discharge, fast transients, and extreme temperatures. Meets or exceeds IEEE 1613 (class 2) and IEC 61850-3 standards for communications networking devices in electric power substations. The SEL-2725 drops no packets throughout this rigorous testing.

Depend on reliability from SEL. Compare our superior specification compliance, lower price, and worldwide, ten-year warranty to alternatives. Directly power the SEL-2725 from 24/48 Vdc or 125/250 Vdc or Vac sources; observed power supply MTBF exceeds 3,000 years.

Easily apply unmanaged “no-settings” switch/media converter. Just connect power, Ethernet devices, and the fiber-optic Ethernet network. LED indicators simplify commissioning and solving network problems. Copper Ethernet ports automatically configure for crossover cables, speed, and half- or full-duplex operation.

Convert Ethernet links to fiber-optic Ethernet links. Use fiber-optic Ethernet links outside of cabinets for increased safety and electrical noise immunity.
