Eaton Controls: Automated Line Testing for LASER Tube Power Supplies

Built on our C8000 and Power Pro platform, we delivered a fast and efficient automated test system designed to meet a wide range of specs with a quick turnaround.

Eaton Controls

Eaton Controls is a power management company based in Dublin, Ireland. Their industry works primarily in the electrical and industrial sector.

Device Under Test

Eaton required an ATE to provide an automated production line testing for their LASER tube power supplies. The customer supplied the UUT test fixture, a LASER tube fixture, a test guideline, and several UUT’s (normal load output voltage is 2.5 to 3.2 kV).


Our engineering team designed a system with an AC and a DC source to input power to their UUT (a high voltage power supply), two programmable resistance substitutes to determine factory selected trim resistors, an oscilloscope, and a DMM. In addition, a custom high voltage relay board was built to automate the ballast resistor selection part of the tests. The application to test the un-potted and potted UUT’s was created using our Power Pro software.


The customer accepted the full Power Pro application test reports of the un-potted and potted UUT’s.
