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 exact title of this standard is: "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 IEC 61000-4-19 describes two different (modulation) test-types which are recommended to use both:
- a sweep test performed with CW pulses with pauses between each pulse
- a test performed with blocks of rectangularly modulated pulses with four different modulation frequencies
sweep test with CW pulses with pauses
- A standard Conducted Immunity test should be performed, using a dwelltime of at least 3 seconds
- Between each tested CW frequency, the level of the test signal is zero for a period of 300 ms (with a tolerance of +- 200 ms). This creates a 'Pulsed CW test with pauses'.
- A 2% frequency step will be used to step from 2 kHz to 150 kHz.
sweep test with rectangularly modulated pulses
- A standard Conducted Immunity test should be performed, using a dwelltime of 3 seconds.
- A 2% frequency step will be used to step from 2 kHz to 150 kHz.
- Between each tested CW frequency, the level of the test signal is zero for a period of 300 ms (with a tolerance of +- 200 ms).
This test should be performed 4 times, where each test is using pulse modulated (with a 50% duty cycle) CW signal. Depending on the AC Mains frequency the pulse modulation frequencies should be:
| AC Mains frequency | Pulse modulation frequencies |
|---|---|
| 50 Hz | 3 Hz, 101 Hz, 301 Hz, 601 Hz |
| 60 Hz | 4 Hz, 121 Hz, 361 Hz, 721 Hz |
