Guarantee for fair & correct billing

By accurately recording and analyzing parameters, DC measurement devices help to ensure the efficiency, safety and reliability of systems by detecting and eliminating overloads, short circuits and other potential problems at an early stage. These devices can measure important parameters such as current, voltage and power and are used in a variety of applications, such as battery management systems, renewable energy systems, electric vehicles and industrial control systems. 

Precise direct current measurement provides operators of fast-charging stations for electric vehicles, for example, with transparent data for recording measured values in compliance with calibration law and MID.

A DC meter is ideally suited to ensure precise measurement and correct billing of the energy purchased by the customer, as it not only provides the operator with the required data, but also plays an important role in consumer protection.  

Flexible & tamper-proof

DC energy meters for customized solutions

The display and sensor unit can be flexibly installed separately. Despite the compact design, all housings offer protection against tampering. The display unit can be optionally combined with the sensor unit SU-125, SU-1000 or
SU-1500 (IEM-DCR-125, IEM-DCR-1000 or IEM-DCR-1500).

All variants can also be used as stand-alone ISA-SCALE® Energy Meter DC Charging Sensor (DCS-125, DCS-1000 and DCS-1500), ideal for the development of individual DC measurement systems.

For customer-specific solutions with other current or voltage levels, please contact us.


Flexible
installation

The physically separate installation of the display and sensor unit increases flexibility in terms of positioning and can therefore respond to different installation requirements.

Tamper protection & user security

Effective tamper protection that ensures the security and integrity of the measurements. This is particularly important for compliance with legal metrology regulations.

Versatile application options

It can be used both as a combination of display and sensor unit and as a stand-alone DC charge sensor, enabling a high degree of adaptability.
