Overview
The 3ctest VTE-743T1 is mainly designed to conduct voltage emission test as per ISO 7637-2. The sketch map is shown below. It is consist by 2 switches, shunt resistor and an artificial network as per ISO 7637-2. During the transient emission test, a switch should be controlled at the same time. Switch MS-743T1 is a standard automotive relay to measure slow transient emission (pulse in millisecond, amplitude is more than 400V). Switch ES-743T1 is a semi-conductor switch to measure low voltage transient emission (pulse from microsecond to millisecond, amplitude is less than 400V).
