# Power supply

The Enless LoRaWAN gateway offers three power supply options to meet the needs of every installation.

## 1. Removable terminal block 12-24V AC/DC

{% endcolumn %}

{% column %}
Designed for integration into electrical cabinets or on DIN rail, this mode uses a removable terminal block.

* **Versatility** : Accepts both direct current (DC) and alternating current (AC).
* **Voltage range** : Supports a wide range from 12V to 24V, offering great tolerance to common voltage variations in industrial environments.

The **12V power supply unit** (Ref : **POWER 1000-002**) can be used on this terminal block.

## 2. Power over Ethernet (PoE)

{% endcolumn %}

{% column %}
The PoE mode allows the Gateway to be powered directly via the RJ45 network cable. It is the ideal solution for simplifying wiring. It requires a PoE switch or a PoE injector compliant with standard norms (**802.3af/at**).

{% endcolumn %}
{% endcolumns %}

## 3. 12V DC Mains Adapter (Optional)

{% column %}
This mode uses a standard jack plug for power via a conventional wall outlet.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/rx-lorawan/installation/power-supply.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
