This board has been developed to test the safety-critical error monitoring in electrical and hybrid vehicles. In order to do this, specific isolation errors between high-voltage and low-voltage circuits must be applied.
The insulation error board allows test engineers to integrate errors with a variable resistance of up to 10 MOhm between the high-voltage wires and the vehicle ground or the vehicle connection respectively. Thus, the insulation monitors used in the high-voltage control devices can be tested. Subsequent users can rely on the frictionless functioning of all these protective devices.
