SUK-A0 Series
8*10/100Base Unmanaged PoE Ethernet Switch




The SUK-A0 series is a PoE switch, designed to operate in the harsh environments at the edge of the network. The SUK-A0 series functions at temperatures ranging from -40°C to 75°C. Whether on the factory floor or the street corner, the SUK-A0 series will provide flawless communications when you need it most. The SUK-A0 series is a Switch with the flexibility of eight Ethernet ports, 4 of which are PoE, that may be configured in a variety of copper and fiber optic interfaces. Flexibility is the main feature of the SUK-A0 series, it may be DIN- Rail, Panel, or Rack mounted, and comes with Terminal Block and Power Jack power inputs to match the applications that require a tough, environmentally Hardened Ethernet Switch.
Port 1 ~ port 4 on SUK-A0 series supports IEEE802.3af Power over Ethernet (PoE) Power Sourcing Equipment (PSE) and can detect an IEEE802.3af compliant Powered Device (PD).Using external 48VDC power inputs through Terminal Block or Power Jack, data and power can be transmitted to a Powered Device (PD) over the same twisted-pair Ethernet cable through port 1 ~ port 4 on SUK-A0 series.
