WitrynaThe High Voltage Scanner 3930 can be used as a measurement circuit switch. The 3930 incorporates lead relays that can be switched at voltages of up to 5 kV DC or 5 kV AC. Sequence Maker (an Excel add-in) can be used to create and execute automatic test sequences. The 3930 can be controlled using I/O from a PLC or similar device. WitrynaThe ST4030A is an impulse winding tester, or surge tester, that combines the functions of both a resistance meter and insulation-withstand testing required for electric motor winding manufacturers to improve quality. Meet the needs of more reliable motor windings in light of the increasing use of electric vehicles and self-driving technology.
