Source Requirements
The EN 61000-4-29 imposes certain requirements on the DC test generator used. Not all of these
requirements can be met with the MX Series AC/DC power source. The following restrictions apply:
Capability
Standard Requirement
MX Series
Output voltage range
0 - 360 Vdc
0 - 400 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
25 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.
