Powering Industrial Automation in Harsh Environments

In this episode of the Inside Electronics podcast, we explore how modern industrial automation relies on robust, well designed power supplies to keep demanding systems running reliably. Host Alix Paultre, Editor-at-Large of Electronic Design, speaks with Mike Swenson, Marketing Manager for TRACO North America, about why industrial environments are among the toughest places for electronics, from electrical noise and extreme temperatures to vibration, dust, and moisture.

 They explain how AC/DC supplies and DC/DC converters form a layered power architecture, delivering clean, stable power to controllers, sensors, and communication modules throughout connected factories.

The conversation highlights key selection factors such as total power needs, peak load behavior, standards compliance, environmental protection, and mounting options like DIN rail, PCB, and chassis solutions. Alix and Mike also discuss testing for harsh conditions and the importance of high-reliability designs to minimize downtime and maintenance. The episode closes with a forward look at more efficient, compact, and intelligent power solutions enabling next generation automated systems.
