EM TEST AIF 503N-series 3-Phase Flicker Impedances 16A – 75A
Description
EM TEST AIF 503N-series 3-Phase Flicker Impedances 16A – 75A unifies the required impedance values for two applications (except for the AIF 503N16 model). It offers a flicker impedance with the values in accordance with IEC 60725 for flicker measurements as per IEC/EN 61000-3-3. It also includes a second impedance used for flicker measurements on DUTs with a rated current above 16A which are intended to be connected to a public low-voltage distribution system with a service current of more than 100A.
The inductors used are non-saturable air coils and are manually matched to the specified value.
The AIF 503N-series is used along with the DPA503N for single phase as well as for three phase measurements.
