CTC's industrial High Power PoE switches are specifically designed to meet IEEE 802.3af/at standards for powering network devices with up to 30 watts output per PoE port. With PoE function, It becomes simplified to install network devices such as IP surveillance cameras, wireless access points, IP phones, and other PoE enabled devices in outdoor or remote areas where are hard-to-reach power source. The IGS-402S-4PH(E)24, 6-port unmanaged full-gigabit Ethernet switches, support 4-port Power-over-Ethernet on ports 1 to 4 and 2-port 1000Base-X (SFP slot) optical fiber. Switchable 100Base SFP or 1000Base SFP can set up easily using the DIP switches located on the front panel. The switches are classified as power source equipment (PSE) can be used to power IEEE 802.3af/ at standard devices (PD), eliminating the need of additional power cable wiring. Moreover, it built-in power input booster of 24 VDC and 48VDC for PoE/PoE+ output without external power converters or power supplies, it is able to fit all the common 24/48 VDC power system found in industrial fields or cabinets. The switches support IEEE 802.3/802.3u/802.3x/802.3ab with 10/100/1000M, full/ half-duplex, MDI/MDI-X auto-sensing to provide an economical high-bandwidth solution for your industrial Ethernet network. Wide operating temperature (-40 ~ 75°C), E models, especially for industrial harsh environment applications.
