KEPCO Equipment We Repair — By Category
KEPCO Product Lines We Repair
Our engineers are trained on the full KEPCO product range. Below are the major product families we service.
HSS High-Voltage Power Supplies
Rugged, high-voltage DC supplies (up to 60kV) for X-ray, electron microscopy, and industrial testing. Common faults include output regulation drift, high-voltage transformer failures, and capacitor degradation under sustained load.
OPS Programmable DC Power Supplies
Programmable, single and multi-output DC supplies (0-100V, 0-500A) for semiconductor testing, burn-in, and R&D. Failures typically stem from control board faults, op-amp degradation, and PWM switching circuit issues.
ABM Modular Power Supply Modules
Compact, stackable modules for multi-output systems in telecom and industrial control. Common repair needs include isolated DC converter failures, phase-shift control issues, and thermal management problems.
RPM Rack-Mount Power Modules
19-inch rack-mountable supplies for distributed power architecture in data centres and substations. Typical failures involve load-share regulator faults, isolation diode leakage, and cooling fan bearing wear.
RSX Remote Sensing Supplies
Supplies with remote voltage sense capability for precision lab instruments and process control. Sense line failures and feedback network instability are common root causes of output voltage drift.

Common KEPCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KEPCO equipment arriving at our workshop.
- ✓Output voltage regulation drift beyond specification — KEPCO power supplies employ precision op-amp feedback networks that degrade over time. Op-amp offset voltage drift, feedback resistor thermal drift (especially in HSS high-voltage models), and capacitor ESR changes in the error amplifier stage cause output voltage to slowly increase or decrease, typically by 0.5-2% over months.
- ✓Intermittent shutdown or hiccup mode oscillation — Current-limit comparators in KEPCO OPS and ABM modules develop noise susceptibility or threshold drift, causing false overcurrent detection during normal transients. Unstable feedback compensation or worn protection relay contacts trigger intermittent shutdown cycles, appearing as power cycling at the output.
- ✓High-voltage transformer insulation breakdown or corona — KEPCO HSS high-voltage units experience dielectric stress in transformers operating above 30kV. Humidity ingress, thermal cycling, and aging of winding insulation (especially in transformers stored in humid Indian climates) reduce breakdown voltage, leading to arcing and secondary short circuits.
- ✓Load-share or parallel operation failure in multi-module systems — KEPCO ABM and OPS units used in parallel configurations rely on isolated load-share amplifiers and precision cross-regulation networks. Faulty isolation optocouplers, open-circuit share resistors, or op-amp failures prevent current distribution, causing one unit to overload while others under-deliver.
- ✓Control board EEPROM programming loss or firmware corruption — Programmable KEPCO OPS and RSX models store calibration data and user settings in EEPROM. Power supply glitches, electrostatic discharge, or manufacturing defects can corrupt the non-volatile memory, causing units to forget calibration or fail to boot with error codes displayed on the front panel.
- ✓Output capacitor ESR degradation causing ripple increase — Electrolytic output capacitors in KEPCO supplies (especially OPS and ABM series) age under ripple current stress and heat. Capacitor ESR (equivalent series resistance) increases over 5-15 years, raising DC ripple voltage and potentially triggering overcurrent protection in sensitive loads such as precision lab instruments or semiconductor testers.

What is the typical repair turnaround for KEPCO power supplies?+
Standard repair turnaround is 5-7 working days for bench test, component replacement, calibration, and high-pot verification. Express service (2-3 days) is available for critical production equipment. Complex faults (transformer replacement, control board rework) may extend to 10-14 days. Synchronics provides daily repair status updates via email and phone.
Can Synchronics repair KEPCO supplies with programming or firmware issues?+

We maintain a library of KEPCO factory firmware images and calibration standards. If your unit has lost power-on calibration codes or custom user settings, contact us with your original documentation and we can restore full functionality.
Do you provide warranty and guarantees on KEPCO power supply repairs?+
Yes. All repaired KEPCO units carry a 12-month warranty covering parts and labour. We guarantee that repaired supplies meet KEPCO's original electrical and mechanical specifications, verified by precision calibration and load-testing. For critical or high-value systems, Synchronics can also offer extended warranty (up to 3 years) and preventive maintenance contracts.
What qualifications and test equipment does Synchronics use for KEPCO repairs?+

What is the cost of repairing a KEPCO drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on KEPCO repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your KEPCO unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
