On the drawing boards: Next-gen IoT power control electronics may sit on a PCB smaller than a U.S. quarter

April 14, 2022 By Lee Teschler Leave a Comment

Here’s the rub when it comes to modernizing the outlets, switches and circuit breakers that characterize ac electrical systems: Any innovations must interoperate with an installed base of equipment that may have been in place for decades. Manufacturers say issues surrounding compatibility with installed equipment have slowed the rate of introduction for technologies such as […]
