Antaira LNP-C501G-SFP-bt 5-Port Compact Gigabit Unmanaged PoE++ Switches with 4x PoE++ (240W), 1x SFP and Extended Temperature Options

PoE+ tops out at 30 W, which is not enough for PTZ cameras with heaters, multi-radio access points or small displays. The Antaira LNP-C501G-SFP-bt series raises that to 90 W per port in a small unmanaged industrial PoE++ switch for a DIN rail, with an SFP slot so the high-power devices can sit a long way from the network core. Putting 90 W PoE and the fiber link in one unit removes the separate injectors and media converters that high-power devices often need.

Every LNP-C501G-SFP-bt shares the same design. Four 10/100/1000Base-T(X) RJ45 ports follow IEEE 802.3bt at up to 90 W per port, supporting Mode A, Mode B and 4-pair delivery, and the 240 W budget covers two ports at the full 90 W or all four at an average of 60 W. One dual-rate 100/1000 SFP slot takes the fiber uplink. DIP switches enable Antaira’s PD Remote Reset Technology (PRRT), set the SFP speed and control PoE by port, and PoE load LEDs light at 70% and 90%. Switching is store-and-forward on a 10 Gbps fabric with an 8K MAC table. Power arrives on redundant 48 to 55 V DC inputs, with 53 to 55 V DC needed for 802.3bt output, plus a supply-failure relay, a slow-blow fuse and reverse polarity protection.

The series comes in two temperature grades. The LNP-C501G-SFP-bt is the standard build, rated -10 °C to 65 °C for heated or indoor panels. The LNP-C501G-SFP-bt-T is the extended temperature build, rated -40 °C to 75 °C for unheated enclosures exposed to outdoor temperatures. For cabinets that run from 12 V or 24 V supplies, the LNP-C501G-SFP-bt-24 series accepts 9 to 55 V DC with the same ports.

Antaira names power and utility, water and wastewater, oil, gas and mining, factory automation, security surveillance and ITS as applications for the LNP-C501G-SFP-bt series. PRRT lets a powered device be reset without a site visit, which suits hard-to-reach cameras. Both builds sit in an IP40 metal case for DIN rail or wall mounting, with shock and vibration ratings to IEC 60068-2-27 and IEC 60068-2-6, UL 61010-1 certification and FCC, CE and RoHS marks, and Antaira backs them with its 5-year warranty. Our team can help check the PoE draw of the devices planned against the budget and the supply voltage.
