Industrial Gigabit PoE++ Injector

The StarTech POEINJ1G90W is a hardened Gigabit Power over Ethernet injector that delivers up to 90 W of auto-negotiated power over a single RJ-45 port. It accepts 52 V to 56 V DC through a four-wire terminal block and mounts on DIN rail or wall brackets. The aluminium IP30 housing is rated for vibration, shock and free-fall, with an operating range of -40 °C to 75 °C and an MTBF exceeding 500,000 hours at 50 °C.

Installers needing one high-power PoE link

Network technicians deploying IEEE 802.3bt Type 3 or Type 4 devices such as pan-tilt-zoom cameras or high-power wireless access points will find the 90-watt budget and wide standard compatibility fit the requirement. The unit also supports legacy 90 W proprietary modes including Cisco uPoE, Bosch, AXIS and HDBase-T PoH. Sites that require AC mains input, multi-port injection or fiber uplinks should look at alternative equipment.

90 W PoE++ power budget

The single specification that decides suitability is the 90 W maximum output compliant with IEEE 802.3bt. If the powered device demands more than 90 W, or requires a different voltage range than the 48 V to 56 V DC input, this injector will not meet the need.

Questions about this item

Will this injector power my older IEEE 802.3af and 802.3at cameras while running on the same Gigabit link?

Yes, it supports IEEE 802.3af, 802.3at and 802.3bt up to 90 W, so legacy 10/100/1000 Mbps devices negotiate their class automatically.

How can I verify the injector is delivering power after I connect a PoE++ access point?

The port negotiates 802.3bt Type 3 or 4 and supplies up to 90 W; check the AP's management interface for confirmed PoE class and power draw.

What cables and power source do I need to buy separately for a DIN-rail installation?

The unit has one RJ-45 data port, one RJ-45 PoE++ port and a 4-wire terminal block for 48 V–56 V DC input; supply a DC source and Ethernet patch cords yourself.
