IEC 61000-4-19
The EN/IEC 61000-4-19 standard describes how Conducted Immunity measurements are performed on A.C. power ports in the frequency range from 2 kHz to 150 kHz. The title of this standard is also: "IEC 61000-4-19: Electromagnetic Compatibility (EMC) - Part 4-19: Testing and measurement techniques - Test for immunity to conducted, differential mode disturbances and signalling in the frequency range from 2 kHz to 150 kHz, at a.c. power ports"
Relevant products:
- All equipment operating at a mains supply voltage up to 280 V and a frequency of 50 Hz or 60 Hz.
The 'Van der Hoofden' measurement should be performed using a specifically described test-head. This can for example be the Schwarzbeck VDHH 9502 or the AFJ VDH 30. Then the emission measurement should be performed using the following parameters:
| Frequency Range | 6 dB RBW bandwidth | Measurement time | Frequency step | Detector |
|---|---|---|---|---|
| 20 kHz - 150 kHz | 200 Hz | 100 ms | 220 Hz | Peak |
| 150 kHz - 10 MHz | 9 kHz | 20 ms | 10 kHz | Peak |
The result of the emission measurement results should be used in a calculation to determine the Factor 'F'. The final value of this Factor 'F' should not exceed 0.85 for the measurements to pass.
