Electromagnetic interference resistance for ME equipment
or systems that are not life-sustaining
The device KSK 150 FCis intended to be operated in one of the electromag-
netic environments specified below. The customer or the user of the device
KSK 150 FC is responsible for ensuring that it is operated in such an environ-
ment.
Surges as per
IEC 61000-4-5 ± 1 kV phase-to-neutral
voltage
± 2 kV phase/neutral to
ground voltage ± 1 kV phase-to-neutral
voltage
± 2 kV phase/neutral to
ground voltage The quality of the supply voltage
should be that of a typical business or
hospital environment.
Voltage dips, short
interruptions and
voltage variations
as per
IEC 61000-4-11 < 5% UT
(> 95% dip of UT) for
0.5 cycle < 5% UT
(> 95% dip of UT) for
0.5 cycle The quality of the supply voltage
should be that of a typical business or
hospital environment. If the user of
KSK 150 FC requires continued func-
tion even in the event of interruptions
in the power supply, we recommend
to power the device KSK 150 FC from
an uninterruptible power supply or a
battery.
