Clean Power

[jimbo123]

I am looking for the best way to supply power to electronic equipment in a industrial setting. All power is from a step down transformer
to the panel views , electronic timers ,meters, and plc 's. Everything uses 120volts. Do we need shielded type transformers , tvss . Looking for the best installation for this type of equipment. Any help will be welcomed.
Does anyone know of a web site for this type of installations ?

I'm just going to point to this manufactures web page.

I like the second listing on the page but I'm almost sure that this alone is not an end all solution, in that there's a lot of factors involved with consideration of exactly what's in you power at point of usage!

Transformer correction

Good Luck

While this paper is aimed at large audio/video installations, the same principals apply.

The separately derived system / isolation transformer wiring on page 21 is a good start.
