Hipot Tester ST9110

Hipot Tester ST9110

The ST9110 hipot tester with its extensive functions offers a versatile field of application. The hipot tester can be used to wind test transformers, generators and motors as well as to test electronic components such as capacitors, coils, cores, inductors and filters. Even electrical appliances such as household appliances and non-electrical products such as wire and insulation can be tested by resistance and insulation resistance testing. In addition, automated test systems and medical equipment can be checked. All tests are ensured according to VDE standard EN50191.
