EMC-PARTNER TRA3000 S - EUT Power Supply with Variac

TRANSIENT3000
53/162
Solutions:
1. For testing with TRA3000 F-S-D-V-C use a power supply without a fault current protective switch.
2. Connect an insulation transformer between power supply and TRA3000 F-S-D-V-C. One
secondary output terminal of the transformer must be grounded.
As a results of the leakage current always connect two earth leads to the TRA3000 F-S-D-V-C.
