Antaira LNP-0802C-SFP-24 8-Port Gigabit Unmanaged PoE Switches with 6x PoE+ (180W), 2x Combo SFP, 12-55V DC Input and Extended Temperature Options

Six PoE+ devices on a 12 or 24 V DC cabinet supply, with an uplink that might end up copper or fiber, is a hard brief for a standard 48 V switch. The Antaira LNP-0802C-SFP-24 series is built around it: industrial unmanaged PoE+ switches with six Fast Ethernet PoE+ ports, two gigabit combo ports usable as RJ45 or SFP, and a built-in voltage booster that produces the PoE supply from 12 to 55 V DC.

Every LNP-0802C-SFP-24 switch has six 10/100Base-TX RJ45 ports with IEEE 802.3at PoE+ at up to 30 W each, plus two gigabit combo ports, each usable as RJ45 or SFP, so each uplink can be copper or a 100/1000 fiber transceiver. Switching is unmanaged and store-and-forward on a 5.2 Gbps fabric with an 8K MAC address table, 9.6 KB jumbo frames and a 4 Mbit memory buffer, so the switches pass traffic and power devices with no set-up. Power arrives on 12 to 55 V DC redundant inputs on a removable terminal block. A built-in voltage booster produces the PoE supply, and the budget depends on input voltage: 60 W at 12 V DC and 180 W from 36 to 55 V DC. One relay output gives a power failure warning, and antaira builds in high EFT and ESD protection against unregulated voltage, with reverse polarity and overload current protection on the input.

The series comes in two temperature builds. The LNP-0802C-SFP-24 is the standard build, rated -10 °C to 70 °C, for heated or indoor cabinets. The LNP-0802C-SFP-24-T is the extended temperature build, rated -40 °C to 75 °C, for unheated outdoor enclosures and other sites that see hard frosts. Both share the same ports, power input and PoE budget. The PoE budget depends on input voltage in both builds, so a 36 to 55 V supply is the one to choose for six devices at 30 W.

Antaira designs the series for rugged, harsh industrial environments. The LNP-0802C-SFP-24 series is housed in an IP30 metal case for DIN-rail mounting, with wall-mount hardware included, and is rated for shock to IEC 60068-2-27 and vibration to IEC 60068-2-6. Antaira lists the series as UL Class 1 Division 2 and UL 61010-1 certified, with CE and FCC marks and RoHS compliance, and both builds carry Antaira’s 5-year warranty. In practice, the choice between the two builds comes down to the coldest temperature the installation will see.
