PT-POS401GRF-OT is a 4-ports ourdoor use PoE switch with 2 Pair PoE, each port up to 30 watts of power at 55 VDC at 0.55 amp. It has sealing gasket inside which passed extension, bearing, corrosion, aging test. 4 ports includ 1 SFP port and 3 PoE output ports with 6KV (10/700us) surge protection. PoE Switch for VoIP phone It suppots 10/100/1000-Mbps of data speed. It is compliant with IEEE802.3af/at standard equipments, such as wireless APs, network camera, VoIP phone, base stations, and other high power Ethernet terminals.It has detection chip inside, which will detect and classify PD before powering it. It will not provide power until a standard-compliant PD is detected. PoE Switch for base stations Enclosed in an IP67 waterproof metal casing, designed for outdoor installation with installation kit PT-POT-MBK, no need to open the equipment. It operates with input voltage of 100-240Vdc, 50 or 60 Hz. The effective distance limitation of 100 meters over Cat5e/Cat6 cables can be extended with the PT-PEX-01G-OT(Outdoor or Indoor PoE Extender). switch industrial poe Specifications Parameter Description PoE Switch for network camera Key Features 1 SFP +3 PoE ports PoE Switch   Wide temperature solutions Lighting Protection Part Number PT-POS401GRF-OT Ports condition SFP Port*1, AC Input Port*1, PoE Output Port*3,Earth Port*1 Regulatory Compliance IEEE802.3 af/at RoHS Compliance WEEE Compliance Pass Through Data Rates 10/100/1000 Mbps Output Pin Assignment and Polarity: 3/6 (+), 1/2 () Output Power Voltage: 55Vdc Output Current: 550mA (Per Port) User Port Power: 30W Guaranteen(Per Port) Input AC Input Voltage: 100 to 240 Vac AC Input Current: 2A Frequency: 47 to 63Hz (50/60Hz Typ.)
