The H51 series of L2 PoE Switches are designed with IP67, 6KV Ethernet port surge protection, 40KV surge protection in power supply , and harden-graded standard to operate between -40° C and 65° C for harsh weather conditions.
They enable outdoor connections of PoE PDs to the network such as outdoor IP cameras, wireless APs, and other outdoor industrial applications.
The H51 series providesmulti-port Gigabit PoE (10M/100M/1G) delivering data and power to PoE PDs over a single network cable and additional SFP transceiver slots for flexible uplink. The H51 series has three sub models classified as power source equipment (PSE) and provide PoE budget up to 30W or 90W per port.
