ACOPIAN Product Lines We Repair
Our engineers are trained on the full ACOPIAN product range. Below are the major product families we service.
ACOPIAN Regulated DC Supplies (12V, 24V, 48V Series)
Fixed-output regulated DC power supplies used in PLC cabinets, motor control stations, and instrumentation racks. Common faults include output voltage drift, blown pass transistors, and electrolytic capacitor failure under Indian ambient heat conditions.
ACOPIAN Variable Output Power Supplies (0-30V, 0-60V)
Adjustable DC supplies with potentiometer control for lab testing and equipment calibration. Repair typically involves non-linear output response, reference voltage instability, and control potentiometer intermittency.
ACOPIAN Battery Charger Modules
Constant-current, constant-voltage battery charging power supplies for UPS and emergency backup systems. Prone to charge rate regulation loss, current sense circuit failure, and thermal protection relay sticking.
ACOPIAN Compact Industrial Supplies (Enclosed Metal Case)
Rugged enclosed power supplies rated for factory floor, foundry, and vibration-prone environments. Repairs address fan motor bearing wear, internal wiring chafe, solder joint fatigue, and connector corrosion.
ACOPIAN Switching Power Supplies (Modern Series)
High-efficiency switching-mode supplies introduced for telecom and precision instrument applications. Common issues include PWM controller IC failure, output filter capacitor dry-out, and feedback loop instability under load transients.

Common ACOPIAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ACOPIAN equipment arriving at our workshop.
- ✓No output voltage, blown pass transistor — Electrolytic capacitors in input filter or output stage degrade over 10-15 years in Indian industrial heat (40-50°C ambient). Capacitor ESR rises, causing pass transistor current surge and failure. Common in older ACOPIAN 24VDC and 48VDC supplies.
- ✓Output voltage drifts or unstable under load — Reference voltage IC (typically TL431 or similar) develops creep, or feedback divider resistors drift with age. Solder joints on error amplifier stage may crack due to thermal cycling in factories without climate control.
- ✓No cooling fan operation, thermal shutdown — Fan motor bearing wear from continuous operation in dusty Indian foundries or textile mills. Alternatively, thermal protection relay fails or fan control circuit transistor opens due to high ambient temperature exposure.
- ✓Output voltage regulation fails under line input voltage variation — Line voltage sensing circuit (often simple resistor divider) becomes unreliable due to connector oxidation in high-humidity environments (coastal Indian locations). Alternatively, series regulating element (pass transistor or LDO IC) has excessive leakage current with temperature.
- ✓Current limit circuit non-responsive, short-circuit damage — Current sense resistor corrodes or opens, bypassing the current limit detection. Current limit comparator IC drifts out of spec. In newer switching supplies, PWM current loop becomes unstable.
- ✓Intermittent operation or spontaneous resets under transient load — Output filter capacitor internal ESR increases dramatically with age, causing voltage sag ripple during sudden load steps. Also common: marginal solder joints on power stage that fail under mechanical vibration from nearby machinery.

Frequently Asked Questions — ACOPIAN Repairs
Do you repair ACOPIAN power supplies at your Vadodara facility?+
Yes. Synchronics Electronics is headquartered in Vadodara, Gujarat and repairs the entire ACOPIAN regulated DC supply portfolio. We offer PAN India pickup and delivery — customers ship from Mumbai, Delhi, Bengaluru, Chennai, Hyderabad, Pune, Ahmedabad, and 50+ other Indian cities. Standard turnaround is 7-10 working days; emergency repairs are completed within 48 hours.
What is the warranty on ACOPIAN power supply repairs?+
All ACOPIAN repairs carry a 90-day full functionality warranty covering parts and labour. We replace all internal capacitors, diodes, and transistors with industrial-grade components rated for Indian climatic extremes (40-50°C ambient). If the supply fails within 90 days from the same root cause, we repair it free of charge.
Can ACOPIAN power supplies be repaired if they are over 20 years old?+
Absolutely. Synchronics has experience repairing ACOPIAN supplies manufactured in the 1990s and early 2000s. Older supplies typically need full capacitor replacement and pass transistor upgrades, as electrolytic capacitors degrade significantly in hot Indian factory environments. We source cross-compatible replacement components and test thoroughly to ensure reliable operation for another 5-10 years.
Why does my ACOPIAN 24VDC supply lose output voltage under load?+
The most common cause in Indian industry is capacitor degradation in the feedback filter network or output stage. High ambient temperature (40-50°C continuously) in non-air-conditioned control cabinets accelerates capacitor dry-out. Synchronics performs complete ESR testing, replaces all electrolytic capacitors with 105°C rated units, and re-measures the feedback loop Bode plot to restore proper output impedance and load regulation.
Do you offer on-site repair of ACOPIAN supplies in large manufacturing plants?+
Yes. For large batch repairs or critical supply failures affecting production, Synchronics can arrange on-site diagnosis and repair at your factory or plant site across India. We carry common spare modules and replacement components. Charges are based on travel and on-site labour hours. Contact our service team at support@synchronics.co.in or call for urgent on-site support.
How do I send my ACOPIAN unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ACOPIAN 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 ACOPIAN 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 ACOPIAN 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.
