DC counters

DC Energy Meters (Direct Current) play a role in monitoring and billing energy consumption in applications such as electric vehicle chargers, energy storage systems, and photovoltaic systems.

Traditional AC energy meters are not designed to work with direct current, so specialized devices are required for such applications to ensure accurate, stable, and safe measurement of electrical parameters. DC energy meters from the DCBM series by LEM, offered by DACPOL, stand out with innovative measurement technology, ease of integration, and certification enabling legal energy billing within the European Union and North America.

Thanks to the use of modern measurement methods and robust construction, DCBM meters guarantee reliability and long service life, which is crucial for the development of electric vehicle charging infrastructure and smart energy grids.

Products from the DCBM Series – Model Overview

The DC energy meters series DCBM from LEM is a comprehensive offer of devices dedicated to precise energy measurement in direct current installations, especially in the electromobility sector. DACPOL, as the official distributor, offers two main models that meet different market needs and power ranges.

DCBM 100 is an energy meter designed for electric vehicle chargers up to 30 kW. It is a compact device designed for easy and quick installation, with the possibility of integration into existing energy management systems. Thanks to accuracy class B and a wide voltage range from 150 to 1000 V DC, the DCBM 100 model works perfectly in lower-power EV charging stations, offering bidirectional energy measurement, which is particularly important in Vehicle-to-Grid (V2G) systems.

For larger and more demanding installations, the DCBM 400 and DCBM 600 models are designed, supporting significantly higher current levels (up to 400 A and 600 A, respectively). These meters are ideal solutions for higher power chargers and energy storage systems, where precision and durability are crucial. The rugged construction and advanced measurement features allow reliable operation even in harsh industrial environments.

All meters from the DCBM series are equipped with displays and offer advanced communication capabilities, such as OCMF, HTTP, and API protocols, facilitating their integration with energy management and billing systems. This allows users to monitor energy consumption in real time and quickly implement new billing models for their customers.

Applications of DC Energy Meters

DC energy meters from the DCBM series find wide application in modern systems related to electromobility and energy management. Due to precise DC current measurement, they are essential components in electric vehicle charging installations, where measurement accuracy and reliability translate into correct energy consumption billing.

The most common application of DCBM models is in electric vehicle charging stations – both smaller home chargers and large public or industrial stations. These meters enable bidirectional energy measurement, which is especially important in Vehicle-to-Grid (V2G) systems, where the vehicle can not only draw but also return energy to the grid. This gives users full control over energy flow and allows the use of advanced billing options.

Besides EV chargers, DCBM meters are also used in energy storage systems – both smaller home storage and large industrial installations. They allow monitoring of energy flow in DC networks, supporting energy consumption optimization and the efficiency of entire energy systems.

It is also worth emphasizing that thanks to MID/PTB certifications and compliance with European and international standards, DCBM meters guarantee legal and precise energy billing, which is crucial for charging infrastructure operators and energy service providers.

Advantages of DC Energy Meters from LEM

DC energy meters from the DCBM series by LEM stand out on the market primarily due to high manufacturing quality, measurement precision, and modern technological solutions. Here are the main advantages of these devices:

Accurate Measurement and Compliance with Standards

DCBM meters have an accuracy class B and meet strict standards and certifications such as MID/PTB, which guarantees reliability and legality of energy billing. This makes them ideal for commercial and industrial applications where measurement data credibility is crucial.

Quick Installation and Easy Integration

The devices are designed with maximum installation convenience — mounting on a standard DIN rail and an optimized connection process significantly reduce installation time. The meters also offer extensive communication options (OCMF format, HTTP, API), enabling quick and hassle-free deployment in existing energy management systems.

Bidirectional Energy Measurement and Real-Time Monitoring

The bidirectional measurement function (V2G) allows measuring not only the energy consumed but also returned to the grid. This solution is especially important in modern electromobility and energy storage systems. Additionally, the meters monitor key parameters such as current, voltage, temperature, and energy, providing full process control.

Durable and Safe Construction

IP20 rated enclosure, reinforced insulation up to 1000 V DC, and detection of incorrect connection and overheating ensure durability and safety even in demanding industrial conditions.

Support for Modern Billing Models

Thanks to the built-in display and remote communication capabilities, DCBM meters enable the implementation of innovative billing models that consider not only the amount of energy consumed but also parking time or dynamic tariffs.
