Antaira LNP-0500G-24 5-Port Gigabit Unmanaged PoE Switches with 4x PoE+, 12-36V DC Input and Extended Temperature Options

Most PoE switches expect a 48 V supply, which leaves a 24 V DC control cabinet needing an extra power supply just for the cameras. The Antaira LNP-0500G-24 series removes that step: a five-port Gigabit industrial unmanaged PoE switch with a built-in voltage booster that takes 12 to 36 V DC and supplies PoE+ to four devices from the same feed as the rest of the cabinet.

Every LNP-0500G-24 shares the same design. Four 10/100/1000Base-T RJ45 ports deliver IEEE 802.3af/at PoE at up to 30 W per port, and a fifth 10/100/1000Base-T port carries the uplink over Cat.5/5E cable to 100 m. Switching is unmanaged and store-and-forward on a 10 Gbps backplane with an 8K MAC address table, a 4 Mbit packet buffer and jumbo frame support, so there is nothing to set up. Redundant 12 to 36 V DC inputs arrive on a 6-contact terminal block, the switch draws up to 145 W at full PoE load, and reverse polarity and overload current protection, surge protection to 2,000 V DC and ESD protection to 6,000 V DC are built in.

The series comes in two temperature grades. The LNP-0500G-24 is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LNP-0500G-24-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures, with the same ports, power input and approvals. Where a 48 V DC supply is already in place, the LNP-0500G series is the matching family, and the LNP-0500G-bt-24 series raises each port to 90 W PoE++ on a 12 to 55 V DC input.

Antaira lists the LNP-0500G-24 series as UL Class 1 Division 2 and 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. One relay output gives a power failure warning, and both models carry Antaira’s 5-year warranty. Antaira names security surveillance, ITS traffic monitoring, oil and gas, mining, power and utility, water and wastewater treatment and factory automation as typical applications, and the low-voltage input suits any of them where the cabinet runs on 12 or 24 V DC.
