About Automotive Electrical Disturbances
Automotive electrical disturbances occur regularly in the vehicle primarily due to switching of various vehicle components and affected by the vehicle harness and other parallel loads. There are both emissions and immunity tests required by the standards, of which there are many. The main standards like ISO 7637-2 and ISO 16750-2 define both how these pulses must be simulated and how they are measured and with what limits.
EM TEST ACC Capacitive Coupling Clamp
Precise construction with highest quality surfaces
Coupling of fast transient pulses to I/O lines The capacitive coupling clamp ACC is used to couple fast transient pulses to I/O lines as required in different national and international standards and car manufacturer specifications for automotive testing.
EM TEST CA BS 200N Load Impedance
Verification load for electronic switch 0.6ohm / 50uH as per ISO 7637-2:2004
CA BS 200N - Load Impedance for BS200Nx Electronic Switches The switching behaviour of the BS 200N series semiconductor switches shall be verified on 0.6ohm to 50uH load inpedance. The CA BS 200N is directly connected to the output of the BS 200Nx.
EM TEST RCB 200N1 Transient Immunity Test Generator
Micro-Processor Controlled RCB 200N1 Ensures Easy Operation
RCB 200N1 - Generation of relay switching transients As per FORD FMC1278 and EMC-CS-2009.1 a part of the test pulses is not generated using a transient pulse generator similar to the ones defined as per ISO 7637 but being based on a circuitry including a Potter & Brumfield 12VAC relay and specifically defined components such as inductors, capacitors, resistors and switches with the aim of simulating "real-world transients".
Teseq CDN 500 Capacitive Coupling Clamp
Precision transient capacitive coupler
The coupling clamp CDN 500 is manufactured exactly in accordance with the drawings and specifications of ISO 7637-3 for capacitively coupling the transients onto cables and wiring harnesses. With its characteristic impedance of 50 Ω , the CDN 500 coupling clamp is connected to the generator via a coaxial cable and terminated on the far side with a 50 Ω load resistor.
