ST4030A IMPULSE WINDING TESTER

ST4030A IMPULSE WINDING TESTER

The 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.
