The space-saving EMpro DC energy meters enable direct measurement of currents and voltages up to 650 A/1,000 V DC for billing purposes. The tamper-proof design with data in OCMF format and the calibration log are ideal for use in charging infrastructure.
EMpro DC energy meters measure powers up to 200 kW in accordance with accuracy class C (EN 50470-4) and up to 650 kW in accordance with accuracy class B (EN 50470-3).
Measurement is performed directly via a shunt, and is also bidirectional depending on the version. The compact dimensions save valuable space in your application.
The EMpro DC energy meters have the corresponding approvals for use in kWh-based billing systems.
The tamper-proof hardware and firmware design provides protection against unauthorized access.
In addition, all events that have an impact on billing are recorded in the calibration log.
EMpro DC energy meters provide high reliability in an extended operating temperature range:
Despite their compact design, the products ensure efficient heat dissipation and are suitable for powers up to 650 kW DC at temperatures up to +80°C.
They can also be used at extremely low temperatures as low as -40°C without any concerns.
The integrated RS-485 interface with the simplified SLIP protocol (Serial Line Internet Protocol) enables the communication of measurement data to higher-level control systems.
Save cabling effort with the RJ12 connectors which facilitate the connection of several DC energy meters in series due to their versatile design.
By storing the energy data, permanent traceability of the charging processes is guaranteed. In addition, all billing-related events, such as adjustment of the cable resistance, are recorded in the calibration log.
Send billing-related data in OCMF format to end devices identified as being secure.
Benefit from integrated network solutions consisting of a CHARX DC charging controller, an EMpro DC meter, and other products from Phoenix Contact.
EMpro energy meters with MID certification in accordance with EN 50470 enable submetering, i.e., cost center-specific energy data billing.
The measuring devices record the key electrical parameters such as currents, voltages, power factors, powers, and energy values in all four quadrants. This provides you with information on the feed-in and drawing of active and reactive energy.
The data is forwarded to a higher-level control system, such as an energy management system, via conventional communication interfaces.
EMpro AC energy meters support single-phase 2-conductor, three-phase 3-conductor, and three-phase 4-conductor applications and are available as direct measurement or current transformer versions.
Currents up to 100 A AC can be measured directly over the entire temperature range from -40°C to +70°C. The measurement input via current transformer can be configured for 1 A or 5 A current transformers, whereby the transformer ratio can be parameterized.
An accurate device that is MID-certified by an external notified body gives you a high degree of certainty.
The European Measuring Instruments Directive 2014/32/EU (MID) distinguishes between accuracy classes A, B, and C in accordance with IEC 62053-21 classes 2, 1, and 0.5.
EMpro AC energy meters satisfy accuracy class C or 0.5 and are suitable for increased requirements in the commercial and industrial sector.
When installed, energy meters can be networked with each other via common communication protocols, such as Modbus/RTU or Modbus/TCP, and communicate directly with the energy data management system. This eliminates any time-consuming direct reading on site.
The energy values in all four quadrants are observed for the most part.
Your specific application requirements will determine which protocol is right for you.
Different types of measuring devices are used in many applications. Multifunctional energy measuring devices are used for measurement at feed-in, while energy meters with MID approval are used for billing.
When it comes to energy measurement, Phoenix Contact products basically speak the same language, because the Modbus registers of the energy meters are based on the EMpro multifunctional energy measuring devices. This saves programming effort and ultimately additional costs.
It must be possible to easily read and export data under the conditions of intended use in accordance with EN 50470-1.
All electrical characteristic values and the configuration parameters available via the display pages are displayed on the backlit LCD display of our EMpro AC energy meters.
Other configuration parameters can be configured via the communication interface.
Four mechanical buttons on the front are used for data control and programming.
