Antaira LNP-0500G-bt 5-Port Gigabit Unmanaged PoE++ Switches with 4x PoE++ (180W) and Extended Temperature Options

PTZ cameras with heaters and wipers, multi-radio access points and small edge devices can draw well beyond the 30 W that PoE+ allows. The Antaira LNP-0500G-bt series is a five-port Gigabit industrial unmanaged PoE++ switch for those loads, delivering IEEE 802.3bt power to four devices from one DIN-rail unit while staying compatible with 802.3af and 802.3at devices.

Every LNP-0500G-bt shares the same design. Four 10/100/1000Base-T RJ45 ports deliver up to 90 W per port within a 180 W PoE budget, and a fifth 10/100/1000Base-T port carries the uplink. If the load reaches the budget, PoE priority runs from port one down to port four, and a DIP switch turns PoE on or off by port, which helps when a device needs a power cycle or when a port should stay unpowered for a non-PoE device. Switching is unmanaged and store-and-forward on a 10 Gbps backplane with an 8K MAC address table, a 1 Mbit buffer and 10 KB jumbo frames. Redundant 48 to 55 V DC inputs arrive on a 6-contact terminal block, and Antaira recommends at least 53 V for full 802.3bt output.

The series comes in two temperature grades. The LNP-0500G-bt is the standard build, rated -10 °C to 65 °C for heated or indoor cabinets. The LNP-0500G-bt-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures, with the same ports, budget and approvals. For a 12 to 55 V DC supply the LNP-0500G-bt-24 series keeps the same ports, and the LNP-0500G series offers 30 W PoE+ where devices draw less.

Antaira lists the LNP-0500G-bt series as UL 61010-1 certified, with FCC and CE marks and RoHS compliance, and tests it to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. The switch draws 5 W itself, reverse polarity and overload current protection are built in, and one relay output rated 24 V DC at 1 A gives a power failure warning. Both models carry Antaira’s 5-year warranty. Antaira names security surveillance, ITS traffic monitoring, oil and gas, mining, power and utility, water treatment and factory automation as typical homes for these PoE++ switches.
