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

PoE devices expect power at around 48 V on the cable, yet a great many control cabinets are built around a 12 or 24 V DC supply. The Antaira LNP-0500-24 series bridges that gap: a five-port industrial unmanaged PoE switch that accepts 12 to 36 V DC and still delivers 30 W PoE+ to four devices, so the cabinet needs no second power supply.

Every LNP-0500-24 shares the same design. Four 10/100Base-TX RJ45 ports on ports one to four deliver IEEE 802.3at PoE+ at up to 30 W per port and power IEEE 802.3af or 802.3at devices, and a fifth 10/100Base-TX port carries the uplink. Switching is unmanaged and store-and-forward on a 1.0 Gbps backplane with a 2K MAC address table, auto MDI/MDI-X and broadcast storm protection. Redundant 12 to 36 V DC inputs arrive on a 6-contact terminal block, with total consumption of 145 W at full 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-0500-24 is the standard build, rated -10 °C to 70 °C for heated or indoor cabinets. The LNP-0500-24-T is the extended temperature build, rated -40 °C to 75 °C for unheated outdoor enclosures. The ports, power input and approvals are the same on both. Where the cabinet already has a 48 V DC supply, the LNP-0500 series is the matching family, and the LNP-0500G-24 series moves to Gigabit ports on a low-voltage input.

Antaira lists the LNP-0500-24 series as UL Class 1 Division 2 and UL 508 certified, with FCC and CE marks and RoHS compliance, and tests it to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. Power 1, Power 2 and Fault LEDs show the supply state at a glance, and a built-in relay output alerts engineers when a power failure or port break occurs. Both models carry Antaira’s 5-year warranty, and the low-voltage input makes the series a good fit wherever cameras and access points share a 12 or 24 V DC supply with the rest of the control equipment.
