6.2.2. SW Installation of Switch S2
– S5
During the interruption testing, the DUT may be
discharged through other parallel devices on the
supply. The PFM 200N100.1 can also switch
these types of loads during the interruption.
The following
Switch Type
settings for are
available in AutoWave.control
under
Discharge
Switches
(S2-S5):
Figure 6.6: Switch Type Setting
None (All open)
:
No loading during the interruption. All parallel switches stay open.
<100 m
Ω
(S2)
:
The switch creates a direct short across the DUT. It will result in the shortest
possible discharge time.
100 m
Ω
(S3)
:
In series to switch (S3) is a 100 m
Ω
load. The DUT will be discharged with the
impedance of the 100 m
Ω.
Low (S4)
Discharge of the DUT is performed through a low-impedance load
High (S5)
Discharge of the DUT is performed through a high-impedance load
The various LV standards require a load impedance of <100 m
Ω
(S2) or 100 m
Ω
(S3)
