MT5511 Power Entry module for 1,2 6 and GM pulses 7a/7b

• Switching actions with inductive and other loads influenced by complex inductances of the wiring harness all create disturbances that must be simulated. ISO and SAE have defined these tests as pulse 1, 2a and 6. The MT 5511 produces these test pulses in conformance with the relevant standard

FT 5531 EFT generator for 3a/3b and variants

• The Teseq FT 5531 simulates fast transient interference injected onto a vehicle’s electrical network through switching processes influenced by the wiring harness that can affect the correct operation of electronic units. The FT 5531 simulates EFT bursts with pulse widths of 100 or 150 ns in conformance with the standards for pulse 3a/3b interference phenomena.
