I hope the 5 second interruption was intended to meet Performance Criteria C.
In contrast, I assume the product is to meet Performance Criteria B for the
two dip (reduction) tests. Right?
I'm surprised that India does not have a holdup time requirement under
Performance Criteria B that would be on the order of 10ms to 20ms.

Hi all,
Does anyone have any information about holdup requirements or standards
for
telecom power in India?
This is typically 10 msec for the DC input (and usually 20 msec for
AC/DC
power supplies), but I think due to low power quality, in India a longer time
might berequired
thanks in advance,
Moshe Valdman
