In modern industrial power system design, choosing the correct Overvoltage Category (OVC) is critical. With the rise of Industry 4.0 and the widespread adoption of automation equipment, more and more applications require higher levels of overvoltage protection. This article explores the differences between OVC III and OVC IV to help engineers select the appropriate power category.

As industrial automation, EV charging infrastructure, energy monitoring, and IoT applications rapidly expand, selecting the right AC-DC power module is no longer just a matter of wattage and specifications—it now directly impacts system efficiency, reliability, and compliance with international standards.
This article focuses on three critical challenges engineers face during selection: efficiency, packaging, and EMI mitigation, and outlines how ARCH Electronics helps customers overcome these challenges and accelerate time-to-market.

As energy transition and renewable technologies continue to evolve, Smart Grids and Energy Storage Systems (ESS) are rapidly becoming critical pillars of global energy infrastructure. At the heart of these systems lie power solutions that must be reliable, efficient, and capable of withstanding extreme environmental conditions. Selecting the right power product—especially in the 20W to 1000W range—plays a decisive role in ensuring system stability and long-term performance.
