Energy Meters (MID)

Crucial for trimming costs, comprehensive energy measurement is necessary to optimize energy consumption. WAGO’s portfolio has energy meters that simplify this task while offering several key advantages.

Direct measurement devices are available for currents up to 65 A. For higher currents, we offer an energy meter with transformer connection option.

The devices are compact in size and offer space-saving installation.

New Product

Modbus TCP Module

The new Modbus TCP Module allows direct connection of WAGO’s MID Energy Meters without additional wiring effort, providing the perfect extension to the standard Modbus RTU interface.

The communication module also allows connection of up to 31 additional Modbus RTU subscribers. All modules use push-in connection technology with levers, making connections very easy and time-saving. The module’s flexibility also saves time when retrofitting it into existing systems.

Energy Meters

Reliable data for the energy transition

Decentralized energy generation and electromobility are central elements of the energy transition and require the transition to advanced energy concepts. In addition to many technological challenges, two basic values play a major role: accuracy and trust - the domain of WAGO's MID-certified energy meters.

Watt-Hour Precision

Anyone who pays for energy wants to know exactly how much has been supplied and at what price. WAGO Energy Meters with MID certification are the ideal solution for all tasks in the building and industrial sectors, as well as in charging infrastructure.

Thanks to their MID approval, WAGO Energy Meters for comprehensive energy consumption measurement can also be used for consumption billing. Watch the video to learn more.

The New Energy Meters

Your Benefits at a Glance

Four Interfaces in One Device

A Real Communications Pro

Four interfaces in just one device: Equipped with an M-Bus and Modbus^® interface, as well as two S0 pulse outputs and Bluetooth^®, WAGO’s Energy Meters are true communications pros! This makes the energy meters easy to integrate into any project.

Easy Configuration

Intuitive Configuration

Using our free WAGO Energy Meter Configurator app, the energy meters can be configured easily in no time – no programming required. In addition, the app offers a function for exporting current values to a CSV file and sending them via common messenger apps or email.

Large Display

Total Transparency at a Glance

Especially easy handling: Our energy meters have a large, illuminated display for operation, which makes the most important data available at a glance in a clearly organized form and offers integrated touch-sensitive controls.

Connecting All Conductor Types Quickly

Saving Time at Every Level

Whether solid conductors, fine-stranded conductors or conductors with ferrules: Push-in connection technology with levers makes wiring quick and easy. In addition to saving time, CAGE CLAMP^® connection technology increases safety, since a durable, reliable contact is guaranteed over the entire service life. This prevents problems like overheating of contact points.

Save Space on the DIN-Rail

Real Space Savings

Space within the control cabinet is valuable – so, despite their large displays, we made our energy meters as compact as possible. The direct and DC meters have a width of 72 mm. The version with a transformer connection is especially narrow: just 2 DUs (36 mm).

The Connection Technology for All Conductor Types:

Solid

Fine-Stranded

With Ferrule

Energy Data Acquisition and Energy Data Management

All the energy data can be recorded and displayed in the WAGO Energy Data Management application on clearly organized dashboards.

Plug-In Current Transformers for Billing Measurement

Plug-in current transformers for billing measurements are inductive, single-conductor current transformers. Due to the measurement principle used, these current transformers are exclusively designed for AC network applications.

These plug-in current transformers comply with the conformity assessment procedure (module D) and can be used for billing.

Your Benefits:

Readily combinable with the energy meter with transformer connections
Screwless CAGE CLAMP^® connection technology
Approved for billing purposes

Energy Data Acquisition

The Right Solution for Every Step

The best energy management solution is the one that adapts to you. WAGO offers you several options for achieving this. With our energy management system, you can save a great deal of energy in production, industrial processes and buildings.

Energy Data Management

Parameter Setting – Not Programming

WAGO Energy Data Management – consisting of a software solution combined with a modular control system – records measurement data from different media and variables for energy monitoring. It then processes them for further analysis, archiving and reporting.
