IEC 61000-4-11
<5 % UT (>95 % dip
in UT) for 0,5 cycle
40 % UT (60 % dip in
UT) for 5 cycles
70 % UT (30 % dip in
UT) for 25 cycles
<5 % UT (>95 % dip
in UT) for 5 sec
Not applicable
Mains power quality should be
that of a typical commercial or
hospital environment. If the
user of the AES-U181 requires
continued operation during
power mains interruptions, it is
recommended that the
AES-U181 be powered from
an uninterruptible power
supply or a battery.

Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical commercial
or hospital environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
