13.8 Source Requirements
The IEC 61000-4-29 imposes certain requirements on the DC test generator used. Not all of
these requirements can be met with the iX Series AC/DC power source. The following
restrictions apply:
Capability Standard Requirement iX Series
Output voltage range 0 - 360 Vdc 0 - 300 Vdc
Output voltage variations under load < 5 % < 1 %
Ripple content < 1 % of output voltage < 1 V rms
Rise and fall time into 100 Ohm resistive
load
between 1 and 50 usec 0.3 V/usec
Over/undershoot into 100 Ohm resistive
load
< 10 % < 2 %
Output current, steady state up to 25 A 3001iX 10 A
5001iX 18.5 A
10001iX 37.0 A
Note: The use of a test generator with higher or lower voltage or current capability is allowed
provided that the other specifications are preserved. The test generator steady state
power/current capability shall be at least 20 % greater than the EUT power/current ratings.
This means that for many EUT's a 25 A capable generator is not needed. However, since the rise
and fall time requirements may not be met under all circumstances, this is a pre-compliance test
only.
For full compliance test applications, the test generator must be tested for compliance with the
test generator requirements.
