Subject: RE: [PSES] -60Vdc Telecom supply voltage
Hi Kannan:
When I first replied to your question I was away from my office and simply
named the primary country (Germany) that I clearly remembered
. In
deed there are many different systems and somewhere they might still use 60VDC.
Maybe also in some other ex-Soviet Union countries.
Best regards,
Bostjan

Dear valued members,
can you guide me on nations that uses -60Vdc supply for telecom installations?
Appreciate your valued inputs in advance.
Best regards,

Dear Members,
Request your expert opinion on EFT generator CDN decoupling inductance.
I'm facing a problem while connecting 48V DC-DC converter, with >6A input
current, to EFT generator CDN. DC supply fed through CDN is unstable and
produces huge ripple that leads to my DC-DC converter shutdown.
