Hello

Just wondering what everyone is using for a good power filter for PLC's these days. Thinking about going with the cutler hammer AEGIS-HW style.

Power filter

Back when I was building panels, I liked to filter everything in the panel, as well as provide some TVSS protection. I used a Leviton 51020-WM in series with the secondary of my 480/120 control transformer.

I find the Islatrol 100 series to be cost effective.

NOTHING and I mean NOTHING beats a SOLA isolation transformer.

I have seen both the TVSS and Islatrol fail in situations with high commutation noise due to high HP drives and the sola transformer does not. Your PLC will thank you for the SOLA.

Never used any isolation transformer or filter. Just a 480/120 control transformer worked fine. However, all my applications were less than 500hp dc and ac drives.
