ISO 9001:2000
CTS Series - EN / IEC 61000-3-3 Flicker Test - Includes Amendment 1 & 2
Test Selection
Flicker tests can be run at either 230 V, 115 V or a user specied nominal EUT voltage
and at 50 or 60 Hz. While presently no mandatory test standard for 60 Hz icker
exists, the CTS system applies the algorithm based on the specication for 60 Hz
icker evaluation in IEC61000-4-15.
WiththereleaseofthelatestIEC61000-3-3(includingAmendment1&2)andIEC
61000-3-11 icker standards, the operator has an increased number of options for
dierent types of EUT’s. This is particularly true for the evaluation of d
max
. These new
choices are fully supported by the CTS system.
Test selections are made in much the same way as is the case for harmonics tests,
providing a consistent user interface. Frequently used settings can be saved to disk
if needed and any setup used is automatically saved with the test data recorded
for possible replay later.
Test times for icker generally extend up to two hours depending on the type of EUT.
The CTS icker mode can be run unattended. A large PASS or FAIL marquee can be
set to appear on the PC screen at the end of the test which can be seen across the
room. This means operator time can be used elsewhere more productively while
the icker test is in progress.
IEC 725 Reference Impedance
The required IEC 60725 icker reference impedance is automatically engaged when
a icker test is exectued. iX Series AC power source based CTS congurations (ex-
cept 10001iX-CTS and 30003iX-CTS) can use the programmable output impedance
of the AC Source. For three phase CTS sytems, a lumped reference impedance is
recommended. See application note 119 for details.
The CTS system oers full compliance
icker testing in accordance with the
latest revisions and amendments of
the EN/IEC 61000-3-3 and EN/IEC
61000-3-11 icker standards.
New in version 3.0 is measurement of
EUT inrush current, semi-automatic
data acquisition and average calcu-
lation for 24 each d
max
tests and the
new limits of 3.3 % for d
t
and d
c
and
6 - 7 % for d
max
parameters.
A choice of programmable and
lumped reference impedances is
available for either European or Ja-
panse test requirements.
The CTS system remains one of the
few icker test systems that provide
real-time flicker results, with all
parameters updated every second,
while the icker test is in progress,
eliminating the need to wait for the
end of a two hour test run only to nd
out an EUT failed.
