Industrial PoE Switch: ULTIPOWER 312SFP-2POE-20 (2xGE PoE, 1xFO 2xSC 1000Mbps 20 km)

The ULTIPOWER 312SFP-2POE-20 Ethernet industrial switch enables data transmission at rates of 10/100/1000 Mbps. Its two GigabitEthernet RJ45 ports support auto-negotiation and Power over Ethernet (PoE) functions. The device automatically discoveries PD devices (Power Device) compliant with IEEE 802.3af standard and supplies power to them. This way, it is easy to power network devices located in places without access to AC lines, such as access points, IP cameras, IP phones etc. The switch has been equipped with two optical ports allowing for transmission over a distance up to 20 km.

ULTIPOWER 312SFP-2POE-20 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.
