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".

The EM TEST RCB 200N1 transient generator meets the requirements set out by the FORD FMC1278 and EMC-CS-2009.1 standard document. It is built using the components outlined in Figure F-1 to generate pulses such as CI 220 A1, A2-1, A2-2, C-1 and C-2, CI 260 F and RI 130 A2-1 and A2-2 for which the RCB 200N1 is built into a metal housing. For RI 130 testing the RCB 200N1 offers BNC-type coaxial outputs to connect the specified test fixture needed for this particular test.
