Two specialist companies

• HILO-TESTstarted business in 1978 and offers an
  extensive range of high-voltage test and
  measurement equipment portfolio.HILO-TEST is a
  pioneer in the EMC market.The CAR-TESTER was
  launchd in 2000.
• SpitzenbergerSpiesoffers the most extensive
  Supply Simulation System portfolio in the
  world.The PASXXXX/GN/KFZ family was launcht in
  1999.

Transients inautomotive power systems

• Test pulse 1This test pulse is a simulation of
  transient due to supply disconection from
  inductive loads as used in the vehicle, it
  remains connected directly in parallel with an
  inductive load.Negative pulse 1/2000µs.

Transients inautomotive power systems

• Test pulse 2This test pulse is a simulation of
  transients due to sdden interruption of current
  in an inductor connected in series with a divice
  under test.It simulates transients wich may for
  example occur due to the following after the
  ignition is switched off, dc motors, wich are
  connected to the same swith as the ignition, may
  continue rotating due to their inertia, thus
  acting as generators. Their inductance creates a
  transient on swithing off the supply
  line.Positive pulse 1/50µs

Transients inautomotive power systems

• Test pulse 3These test pulses are a simulation
  of transients, witch occur as a result of the
  switching processes. The characteristics of these
  transients ar influenced by distributed
  capacitance and inductance of the wiring
  harness.Positive and negative Bursts 5/100 ns

• Test pulse 6This test pulse is a simulation of
  transient at the moment of current interuption in
  the ignition coil.Negative pulse 60/300 µs
