The 72V upper limit is still needed also for the future. In Germany as well as in eastern European countries including Russia, the central battery in telecom centres is a 60V (nominal) battery. The uppper limit is 72 V (2,4V x 30). This situation will not change in the near future

I have recently had a discussion with someone who stated that people are no longer specifying a 36-72V input, and that they are specifying 42-56V because it is more standard for todays applications? Does anyone know where the 36-72V input requirement originated and where and when we still need to design to the old specification of 36-72V? Any input would be greatly appreciated. Regards, Paul S.
