# iEM3000 series

Our EMS supports the Schneider Electric **iEM3000 series** of three-phase DIN-rail energy meters with Modbus communication, used for grid and sub-circuit measurement in commercial and industrial installations.

These meters communicate with our EMS over Modbus and share the same Modbus register map, so a single integration covers the supported models.

### Supported devices

* **iEM3555**: three-phase energy meter with Modbus communication
* **iEM3155** *(beta)*: three-phase energy meter with Modbus communication
* **iEM3255** *(beta)*: three-phase energy meter with Modbus communication
* **iEM3355** *(beta)*: three-phase energy meter with Modbus communication
* **iEM3455** *(beta)*: three-phase energy meter with Modbus communication

{% hint style="info" %}
The iEM3155, iEM3255, iEM3355 and iEM3455 integrations are currently available as a beta integration.
{% endhint %}

### EMS functionality

With the current integration, our EMS enables:

* Accurate measurement of grid and sub-circuit energy flows
* Real-time monitoring of power and energy data
* Use of the meter as a reference point for control strategies such as peak shaving and capacity management
