BAUMANN power|box EOL Test


The baumann power|box is the fl exible platform for test engineering applications in power electronics. When used for testing assemblies and control units, it reliably meets the requirements for quality assurance and a zero-defect strategy in production.
Löhnert Elektronik‘s performance testing technology is designed and built according to customer-specific test specifications. The basic tests on a converter module include simple measurement tasks and performance tests on the main circuit of the directcurrent source via the three-phase bridge to the alternating current circuit.
