The ULTIPOWER 311SFP-POE Ethernet industrial switch enables data transmission at rates of 10/100/1000 Mbps. Its GigabitEthernet RJ45 port supports auto-negotiation and Power over Ethernet (PoE) functions. The device automatically discoveries a PD device (Power Device) compliant with IEEE 802.3af standard and supplies power to it. This way, it is easy to power any network device located in a place without access to AC line, such as access point, IP camera, IP phone etc. The switch has been equipped with optical 1000 Mbps SFP port.
ULTIPOWER 311SFP-POE belongs to the group of industrial switches, capable of reliable operation in harsh environmental conditions like increased dust levels, high or low temperature, high humidity. Such switches should also be mounted in hermetic enclosures installed on poles or other structures located outdoors. The ULTIPOWER switches are equipped with Ethernet ports (Fast Ethernet or Gigabit Ethernet, depending on the model) for connecting IP cameras, computers etc. The ULTIPOWER industrial switches are protected by housings with IP40 ingress protection rating (against solid foreign objects greater than 1 mm in diameter). All the Ethernet PoE ports can power the connected devices (after supplying the switch with 48-50 VDC). Each of the industrial switches has been equipped with optical module converting the transmission medium into fiber.
