The ITP series models are managed, industrial grade, L2 Fast Ethernet PoE (Power over Ethernet) switches that provide 12/22x10/100Base-TX and 4x 10/100/1000Base-T(X) ports. Up to 12/16 IEEE 802.3at compliant PoE plus ports are classified as power sourceequipment (PSE) and provide up to 30 watts of power per port with a maximum power budget of 120W. Housed in rugged wallmountable enclosures, these switches are designed for IEEE 802.3af/at compliant powered devices (PDs), such as surveillance cameras,wireless access points, and IP phones. The PoE switches use M12 connectors to ensure tight, robust connections and guaranteereliable connections against vibration and shock. These models are also compliant with EN50155, covering power input voltage,surge, EFT, ESD, vibration and shock, making these switches suitable for industrial applications, such as vehicle, rolling stock, or vessel.With a wide power input range of 24/48/72/96/110VDC (operating range 20 to 137.5VDC), this product series is especially suitable forrolling stock and track side installations.
