PFS 200N Series
Voltage Dips and Drop interruptions
PFS 200N30, N50, N100, N150, N200
Testing of electronic modules in 12V/24V or 42V supply
systems.
Short-term interruptions, micro dips and voltage drop out are
causing malfunctions in electronic modules. These phenomena
are simulated by the PFS 200N power fail generator.
The PFS 200 can be used as an individual instrument or can be
used in combination with all other generators of the series 200.

Using the USB interface the user can have emc problems during burst tests Our experiences says, that usually
the computer USB port is disturbed by interference’s. Therefore a high quality USB cable ( USB 2.0 standard)
must be used.

13 Fail detection FAIL 1 (TEST STOP)
The BNC input FAIL 1 can be used for failure detection at the EUT. If the input is set to ground (chassis) the
PFS-generator will be stopped and the actual test routine is finished. It is not possible to continue this test
routine. A complete restart of the routine is necessary.
A message of FAIL 1 is indicated in the LCD display as well as in the ISM software.
Fail detection FAIL 2 (TEST PAUSE)
The BNC input FAIL 2 can be used for failure detection at the EUT. If the input is set to ground (chassis) the
actual test routine is paused as long as the low level signal is available at the FAIL 2 input.
Without the low level signal the test procedure continues automatically.
A message of FAIL 2 is indicated in the LCD display as well as in the ISM software.

Voltage drops:
Dependent on the preselected test parameters the power supply for the DUT is switched off for a specified time.
The rise and fall time shall be less than 1.5s. The duration td is adjustable in the range of s to s.
The nominal battery supply has to be connected to the PF1 channel input at the rear panel of the PFS 200N. No
voltage shall be supplied to the PF2 channel input.
Voltage dips
Dependent on the preselected test parameters the power supply for the EUT is reduced for a certain time to a
certain dip voltage (reduced supply voltage).
The Nominal Battery Supply has to be connected to the PF1 channel input at the rear panel of the PFS 200N.
This can be an electronic dc source or a simple battery.
The Dip Voltage Supply for the DUT is connected at the rear panel of the simulator to the PF2 connectors. This
external dc source can be controlled by a 0-10V analog control voltage which is available at the rear panel of the
PFS 200N. The RDS 200 voltage source is recommended for this application. The voltage setting then is
controlled automatically by the PFS 200N.

PSA B217110 specifies two procedures for testing the “Microcoupures”:
-Test procedure:
The “Microcoupures” are generated in “Open Circuit Mode”, that means the serial switch of the PFS 200N
is opened and the DUT is disconnected from the battery supply. The DUT discharges internally. No load is
connected for fast discharge.
Therefore the operator has to select “Impedance: High” for testing.
-Verification procedure
The generator must be verified under loaded conditions. The load resistor is integrated in the PFS 200N.
Therefore the operator has to select “Impedance: Low” for verification. In case that the High mode is
selected it is not possible to verify the fast rise and fall times which are specified to be <1s.

F6 Set voltage
For control of an external power supply source an analogue control voltage can be programmed (0-10V dc).
The operator can specify the following parameters:
F1: Max output voltage of the variac. The analogue reference value for this is 10V.
F2: Rated output voltage for the device under test. This voltage shall be specified by the operator and
depends on the type of equipment under test. The variac normally is automatically set to this output voltage.

Test set-up
When setting up the test national and international regulations regarding
human safety have to be guaranteed.
It is recommended to connect the simulator to the ground reference plane
of the test set-up.
The generators of the series 200, UCS, LD, PFS and VDS can be linked
together to a fully automotive test set-up.
The set-up communicates via the IEEE/GPIB bus and is controlled by ISM
ISO software.
For setting up the system see the following figures:
Each generator can be operated individual as a single equipment.
4.1.
Test setup with software iso.control software
Attention
Operating with iso.control connect the VDS 200N to the PF1 input of PFS 200N
Within a software controlled test setup the system must be
wired as shown in the above figure.
-The VDS 200N must be connected to input PF1. This
unit works as the central battery supply unit and is also
used for battery supply simulation.
-The external DC source, EM TEST recommends the
RDS 200 dc source, is controlled by the analog output
voltage which is available at the rear panel of the PFS
200N. The output of the voltage source must be
connected to PF2 input of the PFS 200N.
Within this set-up all settings for dips and dropouts tests are performed automatically.
