Power Supply & Inverter Repair

Power Supply & Inverter Repair

Power supplies and inverters are the backbone of every industrial installation — when they fail, everything downstream stops. From small SMPS units inside control panels to large industrial UPS systems and high-power inverters, our engineers diagnose and repair at the component level, restoring full output specifications and reliability.

What We Repair

Industrial Power Supplies

  • ▶Switched-mode power supplies (SMPS) — 5V, 12V, 24V, 48V rails
  • ▶DIN-rail power supplies for control panels
  • ▶High-current power supplies up to several kilowatts
  • ▶Redundant and parallel-capable supplies
  • ▶Medical-grade and isolation-class supplies

UPS Systems

  • ▶Online double-conversion UPS
  • ▶Line-interactive UPS for sensitive electronics
  • ▶Industrial battery chargers and rectifiers
  • ▶Inverter and bypass module repair

Industrial Inverters

  • ▶Solar inverters and grid-tie inverters
  • ▶Battery inverters and hybrid systems
  • ▶High-frequency and low-frequency inverters

Common Symptoms

!Output voltage missing or out of regulation
!Power supply trips immediately when loaded
!Audible whining, ticking, or popping sounds
!Bulged or leaking capacitors visible inside
!UPS not charging or showing battery fault
!Inverter shutting down under load
!Burnt smell or visible component damage

Our Repair Process

1

Input & Output Test

We start by characterizing the failure mode — no input, no output, wrong output, or load-dependent failure.

2

Component Inspection

Bulged capacitors, burnt MOSFETs, failed rectifiers and transformers are identified and replaced as a set where appropriate.

3

Controller IC Verification

PWM controllers, opto-couplers and feedback networks are tested — these often cause intermittent failures.

4

Load Testing

Repaired supply is loaded with electronic loads or real equipment at rated current for several hours.

5

Warranty Return

Up to 6 months warranty with a written test report.

Frequently Asked Questions

Do you repair UPS batteries?+

Battery cells themselves are not repaired — we test them and recommend replacement where needed. The UPS electronics, chargers and inverter sections are fully repaired.

What about high-power inverters?+

We service inverters up to several kilowatts. For very large systems, on-site diagnosis can also be arranged.

How long do power supply repairs take?+

Typically 3–5 working days. Urgent jobs can be prioritized.
