Energy measuring devices and energy meters

EMpro energy measuring devices acquire your energy data and communicate it to higher-level control and management systems. Configure and integrate the devices in just a few steps using the web-based, user-guided installation wizard. You can also benefit from the simple, direct connection of conventional Rogowski coils, and from the many practice-oriented web server and device functions.
The integrated REST interface and direct connection to the cloud pave the way to the digital world in the Internet of Things (IoT). 24 V versions complete the portfolio.

The user-guided installation wizard enables intuitive configuration and quick startup. Benefit from the fast basic configuration in only three steps:

• Set up the communication interface
• Select the power grid type
• Configure the current and voltage measuring input

Using versions equipped with a Rogowski measuring input will save you a lot of time when it comes to wiring and configuration:

You can directly connect any commercially available Rogowski coil, regardless of manufacturer. The measuring transducer that is normally used is no longer required.

Export the current configuration data along with historically recorded signal and error lists for rapid troubleshooting. Errors and alarm statuses that occur in the system are quickly and unambiguously detected on site, thanks to a color change on the display.

In local networks, the devices can be easily accessed via the integrated REST API. REST or “Representational State Transfer” is a widely used architecture in the field of IT, which is also gradually being adopted in industrial applications. The user-friendly interface architecture uses well-known Internet protocols. Using any browser, data can be retrieved with just a few commands via an HTTP GET request, for example. You do not need long register tables or special knowledge of industrial communication protocols.

Access your measured data and component data anywhere in the world, without using an additional IoT gateway. You won’t need an IoT gateway to aggregate data, to convert between local network protocols and IoT protocols, or for encryption. The IoT-capable EMpro device is able to transfer its data directly and securely to the cloud using a router.

Protect your energy data from unauthorized access: shutting down operating elements at the device will prevent manipulative operations on site. Deactivating the interfaces, you avoid unwanted access to your energy data or unintentional changes of the configuration.

In addition to interfaces for classic industrial communication, the products also have an integrated REST API. IoT-capable versions for direct cloud connection enable global networking in the Internet of Things.

EMpro energy meters with MID certification in accordance with EN 50470 allow cost-center-specific energy data billing. The measuring devices record key electrical parameters such as currents, voltages, power factors, power ratings, and energy values in all four quadrants. The data is forwarded to your higher-level control system via standard communication interfaces.
