Power Supply failure analysis

APS can provide an expert PSU failure analysis service to determine the root cause of your AC/DC power supply failure.

You may have discovered that you have a reliability problem with a PSU in your equipment or industrial machinery. For some, the consequences of obsolescence, unit failure or fire may be catastrophic and improved reliability is imperative. Age related component failure or a demanding environment could be leading to costly problems.

We can undertake thermal analysis, a rigorous circuit design investigation and component suitability study. Our failure analysis studies are strictly confidential and undertaken with the protection of a non-disclosure agreement (NDA).
In addition to our PSU design credentials, APS have repaired over 17,000 power supplies for Customers across the world. We can draw in this vast experience of real-world failures to identify common failure modes and bad practice.

The failure analysis can be used to predict potential the likelihood of future failures. As part of this program, we can also offer repairs, targeted modifications or ruggedisation to improve PSU reliability and mitigate your future losses and liabilities.
