Our supplier LEM introduces the new DCES Series, a range of DC energy meters developed for accurate energy metering and monitoring in DC charging applications.
Available in 600 A and 1500 A versions, the series combines excellent measurement performance, robust design, and cybersecurity features, offering flexibility including the ability to operate as a standalone smart sensor.
The DCES600 is designed for DC fast-charging and destination charging applications, supporting up to 600 A / 1000 V DC.
The DCES1500 targets heavy-duty vehicle charging and other high-power systems, measuring up to 1500 A / 1500 V DC.
Both models feature an RS-485 interface with API support for easy system integration, and include functions such as data authentication, cable loss compensation, 4-wire measurement, and remote firmware updates.

The DCES Series complements LEM’s already existing DCMB series and addresses the growing demand for certified, secure, and precise DC energy measurement. Together with the DCBM Series, the DCES600 and DCES1500 complete LEM’s offer for DC meters used in fast charging and destination charging applications.
