Quality in focus


Production expansion and new automated test systems

New product developments such as the bidirectional power supply PSB 9000 or the power feedback electronic load ELR 9000 HP have fuelled our steady growth over the past years. Continuous growth means also investment in development and manufacturing. Hence, we have expanded our production capacity including automated test systems.

Made in Germany
We have expanded our manufacturing area to 10,000m². We will occupy an additional property in autumn / fall. EA maintains a concept of vertical integration. From SMD and THT assembly, cabling and device construction through to testing and inspection, all processes take place in-house.

Lean processes and high quality
Our focus on lean processes and high quality assurance have led us to further extend our testing and inspection competence. The inspection process begins during manufacture. Directly after building the circuit boards we inspect the resultant sub-assemblies. All circuit boards undergo a function test using a computer aided test system so that the highest level of operational capability is guaranteed before integration into the final device.

Automated test programme
Before our laboratory power supplies and electronic loads are dispatched they undergo multiple tests using automated and computer aide inspection systems: firstly, our associates calibrate all devices and then test all functions. Next, the power supplies and electronic loads undergo safety checks and a continuous stress test in our burn-in-room. Then a specific, protocolled, calibration is made. At the end we make a final test to ensure that all functions are completely operable.
