UltraPoE POE-M931-90W Gigabit IEEE 802.3bt PoE++ Injector
Add up to 90 W of PoE power to a Gigabit Ethernet connection for high-power cameras, wireless access points and other IEEE-compatible powered devices.
The UltraPoE POE-M931-90W is a single-port, 4-pair PoE++ injector with an internal AC/DC converter. It combines data from a non-PoE network connection with power from a 100–240 VAC source and delivers both through the PoE/DATA output—without requiring an external power brick.
Key Features
- High-power PoE output: up to 90 W user-port power over four pairs.
- Gigabit Ethernet: supports 10/100/1000Base-T applications.
- IEEE PoE compatibility: supports IEEE 802.3af, 802.3at and 802.3bt powered devices.
- Universal AC input: 100–240 VAC, 50/60 Hz.
- Integrated power conversion: no external power brick required.
- Automatic powered-device detection: helps protect compatible PoE equipment from incorrect power application.
- Status indicators: LEDs for AC power and PoE pair modes.
- Plug-and-play deployment: suitable for Ethernet links up to 100 m.

Frequently Asked Questions
What does a PoE injector do?
It adds electrical power to an Ethernet data connection so a compatible device can receive network data and power through one cable.
Does the POE-M931-90W support Gigabit Ethernet?
Yes. It supports 10/100/1000 Mbps Ethernet pass-through.
Does it support IEEE 802.3bt PoE++?
Yes. This 4-pair injector supports IEEE 802.3bt as well as IEEE 802.3af and 802.3at devices.
Do I need an external power adapter?
No. The AC/DC converter is built into the metal enclosure; connect an appropriate AC power cord for the installation region.
Can every connected device receive 90 W?
The powered device must be compatible with the injector’s PoE standard and wiring. Actual delivered power is affected by device negotiation, cable length and cable quality.
