Energy installations are increasingly based on direct current – from photovoltaics, through energy storage systems, to EV charging stations. In this article, we explain what DC meters are, how they work, and where they are used. We also take a closer look at the DCBM series from LEM – advanced direct current meters that combine measurement precision with safety and the ability to bill energy in compliance with the MID standard.

Testing integrated circuitsRead moreThe main advantage of analyzing a device’s immunity at the integrated circuit level is that such testing does not require consideration of the influence of the circuit’s design on electromagnetic compatibility (EMC). This analysis includes, for example, the design of the printed circuit board, the nature and availability of connectors, and the enclosure. The article describes the relationship between testing at the device level and at the integrated circuit (IC) level.

What is EMI and why should you care about it?Read moreEMI (Electromagnetic Interference) refers to unwanted signals that can disrupt the operation of electronic devices. As electronics become smaller and more complex, they also become more susceptible to such interference. EMI can lead to errors, instability, or even system failures. That’s why proper circuit design — including electromagnetic shielding at the PCB level — is so important. This article explains how EMI shielding works, what materials to use, and how to avoid common design pitfalls.
