Requirements of power supply
Declare Ssc that corresponds
to the minimum Rsce value
that satisfies the limit value.
Conforms to 61000-3-12 2011
when short-circuit power upon connection
with the commercial power is equal to
or greater than the declared Ssc.
Conforms to

The expression of each item is simplified. For details, refer to the standards.
Set the impedance of
the power supply to at
least the estimated Rsce.
Set the impedance of the
power supply to at least
1.6 times the estimated
Rsce.
Is the minimum Rsce value that
satisfiesthe limit value equal to or
less than the estimated Rsce?
