How a repair is proven before it comes back
Nothing is signed off on a power-up. Every unit in this category goes through:
- Load testing to rated output
- Insulation resistance verification
- Protection devices confirmed operating
- Enclosure sealing checked before return
Board-level rework is carried out by IPC7711 and IPC7721 certified technicians working to ISO 9001:2015, and the test evidence comes back with the unit.
How a repair actually runs
Four stages, one point of contact throughout. You deal with us; we deal with the workshop.
-
We collect
Tell us what has failed and where it is. Collection is arranged across the UK at no charge, and the unit is booked in against your account with its serial, its symptoms and who reported them.
-
We diagnose and quote
The unit is bench-tested to confirm the reported fault before anyone opens it, then stripped to component level. You get a fixed quote and an honest verdict — including when replacement is the better buy.
-
We repair
Board-level rework is carried out by IPC-7711/7721 certified technicians working to ISO 9001. Failed components are replaced with tested equivalents, not bodged around.
-
We prove it, then return it
Nothing ships on a continuity check. Units are soak tested, load tested and exercised against manufacturer software, and come back with the test evidence and a 12-month warranty.
Are trailer-mounted transformer units repairable?
Yes. These are robust units whose failures are usually in the control gear, the connectors or the enclosure rather than in the transformer core itself — and all of those repair straightforwardly.
Given what a replacement unit costs and how long one takes to arrive, repair is almost always the better commercial answer.
Got a unit that needs looking at?
Send the make, model and what it is doing. You will get a straight answer on whether repair is the right call.
