Atec Pacific-Power-M6204 - Manual

IEC Flicker Impedance M6204 IEC Flicker Impedance
The M6204 unit provides the requisite lumped impedance between the AC Power
Source and the Unit Under Test (UUT) used to test for flicker compliance to IEC 61000-
3-3. Designed to meet IEC 60725 - Consideration of reference impedances and public
supply network impedances for use in determining the disturbance characteristics of
electrical equipment having a rated current ≤75 A per phase – the M6204 simulates
the typical public utility impedance characteristics found in most European countries
in order to provide a common flicker measurement reference.

A separate impedance network in the Neutral leg ensures full compliance to IEC
61000-3-3 and IEC 60725 even under imbalanced three phase load conditions. The
same three phase Impedance network is also fully capable of supporting single
phase Flicker test. In this case, the Phase A impedance and Neutral impedance
combine together to provide the required Z
ref
= 0.40 Ω + 0.25 j Ω single phase
impedance.
Three Phase and Single Phase UUT Testing
The use of high quality components with low thermal drift and high saturation
resistance ensures a stable impedance network throughout the entire flicker test
duration – typically two hours. This is augmented by efficient yet quiet forced
air cooling. Testing to the full 16 Arms per phase as required for products that
fall under the IEC 61000-3-3 Flicker Standard is fully supported by this lumped
impedance with ample margin for temporary overload conditions.

The M6204 impedance is factory calibrated and matched to the AMX AC Power
Source Model it is used with. This ensures that the combination of AC Source
Output Impedance and Lumped Impedance adds up to the requisite IEC 60725
Impedance values. This prevents unwanted system level errors that can occur
when the IEC Flicker Impedance is sourced from a different vendor as the AC
Power Source.
