Thousands of production, QA, design and test engineers use Voltech’s transformer testers for testing transformers, chokes, inductors and other wound components. Our transformer testers along with our software allows the capability to perform transformer quality analysis and transformer quality reporting. Voltech’s automatic transformer testers result in product that has 100% test coverage with 100% quality. Voltech makes testing power chokes and inductors easy with our combined automatic transformer tester and DC Bias current source, both configured automatically for tests which require external bias current. . There are forty plus tests to choose from for testing transformers, chokes, inductors and other wound components such as inductance with bias, interwinding capacitance, leakage inductance and inductance in circuit.

Voltech solutions for power chokes and inductors include accurate measurement of inductance in circuit in the final product and by using dc bias current to simulate working conditions. With the Voltech AT Series testers and the innovative DC1000 dc bias supply it’s never been easier or more cost-effective to production test power chokes and inductors at up to 250 amps and provide 100% confidence through 100% automatic testing at high speed.
