The BS 200N100 is used to evaluate automotive electrical and

electronic components for conducted emissions of transients

along battery fed or switched supply lines of a Device Under

Test (DUT). A device under test which is considered a potential

source of conducted disturbances should be tested according to

ISO 7637 part 2. The BS 200N100 and BS 200N100.1 include

an electronic switch for repeatable switching of inductive loads

as specified in ISO 7637-2:2011 yet supporting former standard

editions.

via an external trigger signal at the BNC plug EXT.

AUTO : After switch TEST ON button, the BS 200N100 switch starts to work.

2 Switch Mode

Setting of the switch mode:

- NO : (Normally Open) The switch is normally open and close at each event.

- NC : (Normally Closed) The switch is normally closed and opens at each event.

3 LED Switch closed

The LED is lighted during the switch is closed.

4 Manual Trigger

Select “Manual trigger” mode of the switch. (open and closing time depends the time setting)

- OFF : Initial state

–ON : One switch event is released.

5 TEST

1 Power IN + supply

The battery supply +IN for the DUT is connected to this input. The switch is located between POWER +IN

and DUT +plug. The nominal dc supply parameters are 60V / 100A .

2 Power IN - supply

The battery supply -IN for the DUT is connected to this input. Internal is a direct connection to DUT- plug.

3 Monitor DUT

Monitor output for voltage measuring (divider 200:1, 5%). The monitor measures the voltage at the DUT

side. The BNC output plug is isolated.

For transient emission measuring an external voltage probe with >400MHz bandwidth must be used.

4 CRO Trigger OUT

Trigger output for an oscilloscope trigger. Trigger with a negative slope (+15V to 0V).

5 Trigger IN

The Trigger IN (Umax. +15V) has two different modes

1. External trigger input for start a single switch event using the duration, setting with the potentiometer.

The trigger shall be a zero going signal (BNC to GND.

2. Direct switch control ON/OFF (LV124 application)

The trigger controls direct the switch. This happens normally with the PFS 200 generator trigger out

signal. For set the BS 200N100 in this mode, the user must press during the power on time the “Manual

Trigger” button. A short LED blinking confirms the correct setting.

Operating manual V 1.12 7 / 21

Equipment description

The Switch BS 200N100 is designed with the following main components:

- Electronic switch

- Differential Voltage divider 200:1

Figure 3.1. : General diagram BS 200N100

3.1.

Electronic switch

The electronic Switch has 2 operating modes:

NC : Normally Closed

NO : Normally Open

Figure 3.2 shows the both operating modes with the

variable parameters “Repetition“ and “Duration“

The electronic switch disconnects the DUT from battery

supply voltage for a specified time in a well specified and

reproducible manner.

Figure 3.2. : Operating modes Switch BS 200N100

The electronic switch is activated by pushing the button TEST. The red LED indicates the closed status.

In AUTO mode the electronic switch is triggered internally with the preselected repetition rate. In MANUAL mode a

single switching event is triggered either bypushing the MANUAL button or by remote trigger.

The electronic switch can switch currents up to 100A and is able to withstand voltages up to 1000V.

The electronic switch is protected against overload and can withstand short-circuit conditions.

Specific protection requirements of the EUT must be separately assured by the user.

Inrush currents

Inrush currents up to 500A are permitted.

Overvoltage

The switch is protected against over voltages higher than 1000V by internal varistors.

3.2.

Divider 1:200

The built in differential divider is designed to monitor the supply voltage. The measuring signal is available on the

MONITOR BNC plug. The 10MHz bandwidth is not designed for measuring the transient emission. The standard

recommends an external voltage probe for this measurement.

The divider is an ohmic- capacitive differential divider with a 50terminating resistor to the BNC plug.

3.3.

Air cooling

The BS200N100 has internal air ventilation for cooling the battery supply switch. Ventilation grid and

ventilator (blower) must be kept away from other devices in order to allow sufficient air flow through the

battery supply switch.
