Power supply and control board repair, cabinet by cabinet
Blown rails, dried-out capacitors, burnt traces, boards with no schematic in sight — we repair industrial power supplies and custom control boards at component level, then verify every rail before it goes back.
Every board gets a reference, a report and a warrantyUn processus construit autour de la confiance
Réception et inspection
Your board arrives, gets logged under its own case reference, and goes through a full visual and electrical inspection for burnt or damaged components.
Diagnostic & devis
We trace the fault component by component — with or without an original schematic — and send a clear quote. Nothing gets repaired until you approve.
Réparation, test & retour
Once approved, we repair the board and verify every output rail under load before shipping it back with a full report.
Common power supply and board faults
- Blown fuses and dead output rails
- Failed switching transistors or MOSFETs
- Electrolytic capacitor degradation ("capacitor plague")
- Burnt traces, connectors or terminal blocks
- Worn or pitted relay contacts
- Failed rectifier diodes and bridge rectifiers
- Component-level faults on custom or unlabeled boards
- Intermittent faults that appear only under load or heat
Repair happens at component level, and we can often work from the board itself even when no schematic exists — tracing the circuit to find what actually failed.
What we work on
- 24V DC din-rail supplies (Siemens Sitop, Phoenix Contact, Mean Well)
- Linear and switch-mode power supplies
- Custom relay and interface boards
- I/O interface and driver boards
- Cabinet-level control boards without documentation
- Legacy and obsolete board designs
What every board repair includes
Traçabilité
A unique case reference and a full repair report follow your board from the moment it arrives.
Load-verified
Every repaired supply or board is checked under load, not just powered on, before it leaves the workshop.
Analyse de la cause profonde
When a board keeps failing, we dig into why — heat, load, or a design weak point — and flag it in the report.
Garantie
Réparations are backed by a standard warranty, so you're covered once the board is back in the cabinet.
Réparer ou remplacer ?
Choisissez la réparation lorsque
- The board is custom, unlabeled, or no longer manufactured
- You want the root cause found, not just a swapped part
- Vous avez besoin d'une réparation traçable avec un rapport et une garantie
- A drop-in replacement doesn't actually exist
Envisagez le remplacement lorsque
- A standard, off-the-shelf supply covers the same spec
- You need uptime now and a matched spare is ready
- A cabinet upgrade or standardization project is already planned
Envoyez-le de la bonne manière
- Photograph the board before removal: orientation, connectors and wiring.
- Étiquetez chaque fil et connecteur au fur et à mesure que vous le déconnectez.
- Écrivez la référence de dossier à la fois sur la carte et sur la boîte.
- Décrivez la panne et ce que la carte alimente ou contrôle.
- Utilisez un sac antistatique et emballez-le de sorte qu'il ne puisse pas fléchir ou se déplacer pendant le transport.
Lorsque la panne ne se manifeste que dans le cabinet
Some faults only appear under real wiring, grounding, or load conditions a bench test can't reproduce. When that's the case, we can send an engineer to you instead.
