Compact DC Metering for Smarter Energy Systems: Meet the IVY EM619025~27 Series

From EV fast charging to battery storage and solar PV, the EM619025~27 series combines high-current DC metering, flexible communication and intelligent monitoring in a compact DIN-rail design.

As EV charging, battery energy storage and distributed renewable energy systems expand, DC power networks are becoming more powerful and more connected. For equipment manufacturers and system integrators, this creates a practical challenge: how to achieve accurate high-current energy measurement without adding unnecessary complexity or occupying excessive cabinet space.
The IVY METERING EM619025~27 series is designed for this new generation of DC energy applications. Featuring an integrated shunt design and compact 3.5P DIN-rail mounting, the series provides direct-connected DC energy measurement for EV chargers, energy storage systems, solar PV installations and other industrial DC applications.
Three current versions are available — 200A, 400A and 650A — with a rated voltage range of 100V to 1000V DC. The meter provides Class 1 energy accuracy and supports both forward and reverse energy measurement, allowing operators to monitor energy consumption as well as bidirectional energy flow in applications such as battery charging and discharging.
Connectivity is another key part of the design. The EM619025~27 series supports RS485, fully compliant with rigorous MID and PTB Eichrecht standards, with compatibility for Modbus RTU, DL/T645-2007, HTTP-JSON and HTTP-OCMF. This makes it easier to integrate metering data into charger controllers, energy management systems, cloud platforms and other digital infrastructure.
Beyond basic energy measurement, the meter also includes practical functions for system operation and maintenance. These include over-current and over-temperature alarms, magnetic field detection, shunt temperature monitoring, line-loss energy compensation, self-diagnosis, network time synchronization, and local or remote firmware upgrades.
With its combination of high-current capability, compact installation and flexible communication, the EM619025~27 series helps simplify DC metering integration while providing the data required for smarter energy management.
For EV charger manufacturers, energy storage suppliers and system integrators looking for a versatile DC metering solution, IVY EM619025~27 offers a practical platform for accurate measurement, connectivity and long-term system monitoring.
