If you want to sneak DC into a system, you'd never get it passed a clamp meter, if you just use some diodes.  You'll need serious decoupling. I say serious, because the load is substantial and will quickly drain the reservoir capacitors. Any ripple on the DC will generate a varying magnetic

Yes, Hall effect clamps are readily available, I am not disputing that. They used to suffer from drift problems, but these problems have pretty much been solved. The one that you show has a 3% accuracy and 8 digits of drift - not bad. The only info I have about Rossi came from a single post
