For over a century, DZG Metering has stood as a pioneer in the field of electricity metering. Founded in 1901, the company has continually evolved, specializing in the development, production, and distribution of cutting-edge AC and DC meters. Adhering to the latest technical standards and stringent calibration regulations, DZG Metering actively supports the global push for a sustainable and efficient energy transition.
In the era of e-mobility, the need for precise and reliable electricity metering has become paramount. As part of its unwavering commitment to the energy revolution, DZG Metering has developed a range of DC and AC meters tailored to the demands of charging infrastructure expansion. These meters, ensure accurate energy measurement, whether for private wall boxes or public charging stations. With advanced features such as compensated energy calculation via line loss calculation of the charging cable or exact voltage measurements directly at the charging cable, DZG’s solutions meet the high standards required by the growing e-mobility sector.
At the heart of this innovation is DZG Metering’s latest product, the GSH4020. This compact, next-generation DC meter sets a new standard in the industry, combining high performance with space efficiency. Measuring just four division units in width, the GSH4020 is the world’s first DC meter of its size capable of supporting a maximum output of 200 kW. Fully compliant with MID, MessEG/MessEV, and UL standards, this meter is designed to seamlessly integrate into modern charging station infrastructure while ensuring compliance with calibration laws.
The GSH4020 offers a host of advanced features that make it a standout choice for technical experts and system integrators. Its compact design enables straightforward installation even in confined spaces, while its robust construction—crafted from fiber-glass reinforced polycarbonate—ensures long-term reliability. The meter’s high-precision measurement capabilities with accuracy class C are complemented by an optional cable loss compensation feature, enhancing its versatility in diverse applications. Integration is simplified through the REST API, and the use of industry-standard cable connections ensures compatibility and ease of use. The device’s transparency and secure billing functionality are powered by the Open Charge Metering Format (OCMF), fully compatible with S.A.F.E. transparency software. For applications requiring calibration compliance, the GSH4020 can be paired with a DZG exclusive external display.
Technically, the GSH4020 is engineered for excellence. It operates over a wide voltage range of 40 to 1000 V and supports a maximum current of 200 A. Its auxiliary power supply spans from 9 V to 24 V DC, ensuring adaptability across various setups. Designed for extreme environments, the meter performs reliably in temperatures ranging from -40°C to +80°C. With dual RS485 interfaces and compatibility with both DIN rail and screw mounting systems, the GSH4020 offers unparalleled flexibility. Additionally, its IP20-rated enclosure provides essential protection, while its compliance with rigorous standards—including MID 2014/32/EU, MessEG/MessEV, UL 61010-1, and CAN/CSA-C22.2 No. 61010-1-12—underscores its quality and reliability.
As the energy sector continues to evolve, the GSH4020 embodies DZG Metering’s dedication to innovation and excellence. Its combination of compactness, precision, and advanced functionality positions it as a vital tool for the e-mobility and industrial sectors, meeting the most demanding requirements of modern energy systems.
Visitors to E-world Energy & Water 2025 are invited to experience the GSH4020 firsthand. DZG Metering will be showcasing this revolutionary product at Hall 5, Booth 5E116, from February 11 to 13 in Essen, Germany.
