Power Supply & Inverter Repair

A power supply or inverter failure can shut down an entire machine. Motors stop, sensors fail, and automation freezes. Whether it’s a power supply unit inside a PLC, VFD, servo drive, CNC system, or a standalone industrial inverter — downtime directly impacts production.

At Epoch Technical Services, an ISO 9001:2015 certified company, we specialize in Power Supply Repair, Inverter Repair, and Preventive Maintenance services for industrial electronics.

We repair down to the component level instead of forcing full replacement.

Repair instead of replace reduce cost, reduce downtime.

Why Choose Epoch Technical Services

Repairs completed in-house in an ESD-safe electronics lab
Component-level diagnostics (IGBT, rectifier, capacitor, SMPS section)
Maintenance, service, and reconditioning of high-usage power boards
Support for obsolete and discontinued units

We don’t do trial-and-error board swaps.
We repair the exact failed component.

What We Repair

Power Supplies

SMPS (Switched Mode Power Supply)
Linear power supplies
24VDC PLC / control panel power supply units
CNC / HMI internal power boards
Tesla-style DC bus supplies for automation panels

Inverters

DC to AC industrial inverters
UPS inverter boards
VFD / servo drive inverter module repair
Industrial AC/DC converter & rectifier boards

Whether the unit powers up intermittently, shuts down under load, or is completely dead ➡ We repair it.

How Power Supplies & Inverters Work

Power supplies and inverters regulate and convert electrical power so that machines and automation systems can run safely.

A failure may occur in:

SMPS switching circuit
DC bus capacitor
Power semiconductor section (IGBT/MOSFET)
Internal feedback & protection circuit

When this fails, boards stop receiving stable voltage causing machine failure.

We restore power delivery stability and performance.

Common Problems We Fix

You may be seeing one of these symptoms:

No power / no output voltage
Overvoltage / undervoltage alarms
Inverter shutdown during load
Blown capacitors or burnt components
Ripple voltage / unstable output
Power fluctuations affecting PLC, HMI, drives

Technical repair actions include:

IGBT & rectifier replacement
PCB trace repair
SMPS section rebuilding
Capacitor bank replacement
Heat sink / cooling system maintenance

Our Repair & Maintenance Process

Evaluation

You share the issue or send the power supply/inverter. We inspect it.

Transparent Quotation

We explain the root cause and repair method. No work starts without customer approval.

Component-Level Repair

We repair the failed components (power stage, SMPS, rectifier, IGBT modules).

Load Testing & Performance Validation

We test output voltage, ripple level, thermal stability, and overload handling.

Ready to Install

The unit is returned ready for reinstallation.

Maintenance Services (Preventive & Predictive)

To extend lifespan and avoid unplanned failure, we offer:

Periodic inspection of capacitor banks
Cleaning & thermal paste service
Fan & cooling system replacement
Preventive inverter maintenance schedule

Preventive maintenance = less breakdowns + longer equipment life.
