Two questions ... 1. Would anyone care to relate personal experiences, anecdotes, concerning the stability or non-stability of the -48VDC rail in a CO?
Just how bad is it? 2. I think I'm finally understanding the meaning of the upper Bellcore range of 56 vdc. UL testing would require +6% above 56 which puts it right at 60VDC. Any change increasing the upper limit in the spec would push the voltage into the hazardous voltage area ( >60VDC ) changing all the test limits. Do I have that correct? Where'd the lower Bellcore voltage spec some from? Regards, Doug McKean
