Develop a wide range of wireless and wired products
to meet various M2M and IoT needs.

Unmanaged PoE Switch



  • Full 10/100 M Ethernet ports
  • IEEE 802.3af PoE & IEEE 802.3at PoE+ complaint
  • 9K jumbo frames
  • L2 wire-speed switching engine
  • 2K MAC forwarding addresses
  • Fanless design and withstand a wide operating temperature range (-40~+75°C)
  • Dual power input (46~57VDC, dual input)
  • DIN-rail and wall mounting option
  • IP30



MLiS unmanaged full 10/100/1000M 5-port Ethernet switches compliant with both IEEE 802.3af and IEEE 802.3at PoE standards and delivering up to 30 watts power per port along with data on standard Ethernet cabling. The switches can be used to power IEEE 802.3af/at standard devices (PD), which eliminates the need for additional wiring and eases the deployment for applications to reach power source.
