Specifications
EMC test equipment1.Meet ISO7637-2 Standard
2.Professional EMC test equipments manufacture
3.TUV certified
EMC test equipment ISO 7637 simulator is designed for automotive electronics equipment immunity test
This test is a simulation of transients due to supply disconnection from inductive loads. It is applicable to DUTs ,which as used in the vehicle, remain connected directly in parallel with an inductive load. Pulse 2a simulates transients due to sudden interruption of currents in a device connected in parallel with the DUT due to the inductance of the wiring harness. Full compliant with the latest standards of ISO7637-2
