Industrial Power Supply Repair in Baku
Industrial power supply repair in Baku — circuit board repair for DIN-rail 24V/48V units, industrial UPS, stabilisers and laboratory supplies: no output, sagging voltage or a unit stuck in protection.
Order
Send the make and model and describe the fault briefly. A video helps most — film the fault. Clear photos of the board help too.
Electronics repair for industrial power supplies: DIN-rail 24V/48V units, redundant supplies, industrial UPS, voltage stabilisers and laboratory power supplies. Component-level circuit board repair — PFC stage, switching transistor, capacitors and BMS.
How we work
Not every device can be repaired
Sometimes restoration is not possible: the chip is discontinued and no spare can be sourced, no donor board is available, the board is severely damaged by fire or liquid, or earlier repair attempts have left it beyond recovery. In such cases we explain the situation plainly and, where possible, suggest an alternative.
When an industrial power supply fails, every piece of equipment behind it stops. We carry out component-level repair on DIN-rail 24V/48V units, redundant supply modules, industrial UPS units, stabilisers and laboratory power supplies.
We work with Meanwell, Puls, Phoenix, Weidmüller, Siemens Sitop, APC and Eaton units — the work is circuit board repair, not buying a new supply. The case we see most is a lost or drifting output voltage; behind it are usually dried-out capacitors, a failed PFC stage or a punctured switching transistor. On three-phase UPS units we also service the battery BMS.
In this area the first step of diagnostics is telling whether the fault is in the supply or in the load. If the unit behaves correctly off-load but trips into protection under load, the problem is often in the load or the cable. Checking that first prevents parts being replaced needlessly.
Devices we repair
Common faults we repair
- No output voltage
- The output voltage sags or drifts
- It goes into protection and will not power the load
- The fuse blows repeatedly
- A burnt PFC stage, the input current is high
- Swollen capacitors and ripple on the output
- The unit hums, the transformer vibrates
- The UPS will not charge the battery
- The UPS drops the load when the mains fails
- The stabiliser will not regulate the voltage
- The fan has stopped and the unit overheats
- A redundant module will not share the load
Typical causes of failure
- Dried-out output capacitors making the voltage drift
- A punctured PFC stage and switching transistor
- Output diodes burnt by an increased load
- A failed varistor and fuse on the mains side
- A swollen UPS battery and a BMS fault
- Internal overheating after the fan stopped
- Dust accumulating on the heatsink and the board
- A short or insulation fault on the load side
Brands and platforms we work with
How the repair works
- 01
Enquiry and first contact
Tell us about the fault on WhatsApp or Telegram. We review what you send and let you know whether the device fits the work we take on.
- 02
Acceptance and diagnostics
If we can take the device on, we confirm it in advance — do not ship it before you have our confirmation. Once it reaches the lab, diagnostics are completed within 48 hours (two working days).
- 03
Estimate and approval
You receive a report covering the cause of the fault, the estimated cost, spare-part availability and the timeline. Work begins only after you approve it.
- 04
Testing and handover
After the repair the device runs a minimum 24-hour load test. Once it proves stable in normal operation, we report the result and hand it over.
Diagnostics and pricing
Diagnostics is paid work — 10–50 AZN depending on the complexity of the board. If you have us carry out the repair, that amount is deducted from the final price. An exact repair price is given only after diagnostics and is agreed with you before any work starts.

Request a repair
Message us on WhatsApp or Telegram with the BRAND and MODEL of the device and describe the fault in as much detail as you can. A VIDEO helps most: record the fault and explain in your own words what happens. Also send clear photos of the device and, if accessible, of the circuit board from several angles. The more detail you provide, the faster and more accurate our answer.
