Fiber isolated Probes from Saker

[mk_]

Hi all

While searching about Diffprobes for small signals on high common mode Voltages (at least 10kV) I found something calles ISOVP from an unknown company named Saker-MV. No Impressum, no price, no more details about the company, no teardowns, just a phonnumber somewere in Spain - maybe.... Google says that they are located in Madrid..

So my question is: does somebody know more about them, specialy about their ISOVP-Probes (https://saker-mv.com/products/) and is willing to share this info here on the forum?

TIA
