ESD: Schlöder SESD 230

The ESD Simulator SESD 230 is suitable for performing EMC tests on systems in accordance with the standard IEC / EN 61000-4-2 (ESD test). Higher test levels can be set far beyond the standard limits. Depending on the test object and test setup, two test methods are to be used:

1. Air discharge In this case, the pulse is triggered by approaching the SESD 230 towards the DUT. The high voltage applied to the discharge electrode is discharged suddenly, resulting in a very broadband high-frequency interference spectrum. This in turn can lead to influences on the test specimens.

2. Contact discharge With this method, the probe of the generator is placed directly on the test object. The actual "impulse triggering" takes place via a relay contact and reduces the influencing factors such as approach speed, amplitude height, air humidity and temperature.
Important: In the case of non-contacting (e.g. painted or oxidized surface), the impulses are not triggered. The display shows "No contact". This ensures that when triggering a discharge actually takes place.

The contact discharge is the favourite test method since it is most reproducible. Air discharges are used when contact discharges are not possible - e.g. at plastic housings.
