Digitus DN-651141 — 802.3bt PoE++ injector for DIN-rail cabinets
IEEE 802.3bt · up to 85 WGigabitDIN rail-40 °C to 75 °C
The Digitus DN-651141 is an industrial single-port Gigabit PoE++ injector that adds IEEE 802.3bt Type 3 or Type 4 power — up to 85 W — to an Ethernet link inside a DIN-rail cabinet. It is aimed at system integrators powering PTZ cameras, Wi-Fi 6/7 access points, small-cell radios or displays from an industrial control panel where only a DC bus is available.
Unlike desktop injectors, it does not plug into the mains: it is fed from an external 45–56 V DC power supply through a 3-contact terminal block. Data passes through shielded RJ45 ports at 10/100/1000 Mbps, and power is delivered on all four pairs (Alternative A and B). It operates from -40 °C to 75 °C.
Before you order: No power supply is included. You need a separate 45–56 V DC DIN-rail power supply sized for the load (for 85 W output, plan roughly 100 W of PSU capacity). Without it the injector does nothing.
What's in the Box
- DN-651141 PoE++ injector
- DIN-rail kit (clip pre-attached)
- User manual
What It Means in Practice
- Lets a non-PoE industrial switch power one high-demand device without replacing the switch.
- Fits next to the existing 48 V DC supply in a control cabinet; one DC feed can serve the injector and other loads.
- 4-pair power reaches 802.3bt Type 3 (60 W) and Type 4 devices; 802.3af/at devices are detected and powered at their own class.
- The wide temperature range suits unheated outdoor cabinets and machine enclosures.
What Will Not Work
- It cannot be plugged into a wall socket — there is no AC input.
- It does not include the 45–56 V DC power supply.
- It is not a switch: one data input, one data + power output.
- It does not convert PoE to 12 V or 24 V DC for non-PoE devices.
Key Features
Up to 85 W
IEEE 802.3bt Type 3 and Type 4 on four pairs, backward compatible with 802.3af/at.
DC terminal input
45–56 V DC on a 3-contact terminal block (12–24 AWG wire).
Industrial range
-40 °C to 75 °C operation, DIN-rail mounting.
Status LEDs
PWR and PoE LEDs; PoE stays lit when an 802.3bt device is detected.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
This is the injector for cabinets that already have a 48 V DC bus, not for desks. Before ordering, confirm the DC supply and the power class of the device. If you would rather replace the switch, see our industrial and PoE switches.
✓ Buy it if you need up to 85 W of 802.3bt PoE in a DIN-rail cabinet with a 45–56 V DC supply.
✕ Skip it if you only have mains power — an AC-powered PoE++ injector is the simpler choice.
→ Also consider an AC-powered 802.3bt injector for office or rack installations.
