PFM 200N100.1 Dropout Simulator
The generator serves as the switching unit for dropout testing both power and signal lines required by
various requirements.
5.1.
Switch for DUT Battery Voltage
- Power Switch (S1P) for currents from 100 mA to 100 A (Inrush 400 A for 200 ms)
- Voltage ± 100 V DC
- Switching time < 1 µs
- Bidirectional switching capability
- Switch (S1N) on the ground line
- Integrated shorting-switch with < 100
mΩ during switch off (S2)
- Additional switchable impedances
(R1…Rx), for predefined impedances of the on board power
system
5.2.
Switches for Data and Signal Lines
- Switch (S1 to S16) for currents from 100 µA to 2 A
(Inrush 5 A for 200 ms)
- Bidirectional switching capability
- 16 switches for each sign or data lines
- Max. ± 40 VDC
The generator may
only
be used with AutoWave

Battery Lines
Switch S1 and S2 from the standards LV 124 and LV
148 have a slightly different name in the PFM
200N100.1 and its associated software. Switch S2N in
the PFM 200N100.1, used to interrupt the ground line,
is not found in the LV requirements, instead other
standards.

Data and Signal Lines
There are two connectors on the PFM 200N100.1, each
with 16 inputs and outputs. The upper row is switched
and the lower row is an unswitched return line.
