In many cases, products needing some extra EMC attention are too large to bring into the lab. In this month’s success story, our Schaffner troubleshooters work remotely to save a client from a catastrophic shutdown.
Dave and Amir Investigate
Schaffner technical experts Dave Armitage and Amir Majedi travelled to the client’s headquarters in Rochester, NY and spent several days troubleshooting remotely with the installation team on site.
Dave and Amir suggested different internal filters and ring cores inside the product in various configurations and locations. They suspected the noise originated from the system’s internal high-speed IGBTs.
After much trial and error, a solution emerged. The Schaffner team placed 3-Phase Filters close to the high-speed switching circuits and upgraded the cabinets’ RF seals.
Heroes in the Making
The combination of the filter and gasketing took the levels of emissions below the required threshold.
These heroic efforts solidified the perception at the site that Dave and Amir were EMC experts – which of course they are.
The inductive heaters now incorporate FN3270H filters from Schaffner in their design and are headed for huge sales and many more successful installations.
MORE POWER TO YOU!
