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 icker 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 icker measurement reference.

THE POWER OF EXPERTISE

The Leader in AC Power Technology

FREQUENCY CONVERSION R & D MANUFACTURINGAEROSPACE MILITARY CUSTOM

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 icker test

duration – typically two hours. This is augmented by ecient 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.

An early pioneer in the development solid-state power conversion equipment,

Pacic Power Source continues to develop, manufacture, and market both linear

and high-performance PWM AC Power Sources. Pacic’s reputation as a market

and technology leader is best demonstrated by its continuing investments in

both research and development and world-wide customer support. With corpo-

IEC 60725 Compliant

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 dierent vendor as the AC

Power Source.
