When reliability matters most...

Unlike general repair houses, our specialised electronics design engineers help reliability-conscious professionals in the defence and aerospace industries who want expert DC power supply repair, refurbishment & design solutions to avoid costly outages and maximise up-time on mission critical equipment.

Repair, refurbish or replace?

What is the way forward for failing legacy DC power supplies?

To you, it is not as simple as just ordering a new PSU for your mission critical radar, ordinance or comms equipment. The original model may be obsolete, or the manufacturer may have closed down. A replacement may even need re-certification! Perhaps you have tried looking for a different unit, but did not feel sure about the correct electrical specification; maybe the design calculations are lost in history somewhere.

Repair is often the economic option but many customers choose use our refurbishment service during scheduled maintenance periods to pro-actively prolong the useful life of power supplies. By predicting the likelihood of future failure of particular component types and replacing them regardless of condition, we can help you maintain legacy systems for decades to come.

Standards matter...

Few general electronics repair houses have an appreciation of the various, often bewildering standards governing Military equipment.

APS have years of experience with the common MIL specs such as Mil Std 461E (RFI emissions and susceptibility), 704E (Voltage transients), 1275D (28Vdc in vehicles), 810F (environmental & shock).

Coming from a design background, we appreciate the impacts on approvals that poorly considered repair processes can have. Diligent component selection is paramount where reliability simply cannot be compromised.

“My company used APS to carry out and present MTBF calculations to MIL217F on a range of units. We were delighted with the quality of work which enabled us to fulfil an obligation with one of our customers much more quickly than if we had carried out the work ourselves.“

David Heaton EP Systems PLC

“An excellent service, good value, with turn around times much faster than quoted. Thanks, we'd almost given up on getting this item repaired.“
