ACEC Product Lines We Repair
Our engineers are trained on the full ACEC product range. Below are the major product families we service.
ACEC Thyristor Rectifiers and DC Power Supplies
Industrial-grade DC power conversion systems used in electrochemical processes, metal rolling mills, and DC motor drives. Common issues include thyristor gate failures, cooling fan breakdowns, and transformer secondary winding insulation degradation.
ACEC Industrial Control Systems and Regulators
Analogue and digital controllers for process automation, load regulation, and closed-loop feedback control in heavy industry. Repair needs include potentiometer drift, printed circuit board corrosion, and signal conditioning module failures.
ACEC Soft Starters and Power Electronics Modules
Solid-state soft-starting solutions and power switching modules for large induction motors in Indian mining, cement, and steel operations. Typical faults include gate drive circuit failures, power semiconductor degradation, and cooling system blockages.
ACEC Legacy Control Cabinets and Distribution Boards
Switchgear, distribution, and control enclosures from ACEC's mature product portfolio, still widely deployed in Indian plant infrastructure. Failures often stem from relay contact wear, wiring harness corrosion, and electromechanical contactor fatigue in harsh industrial environments.
ACEC Feedback and Sensing Devices
Transducers, encoders, and measurement modules for closed-loop industrial control. Common repair issues include connector oxidation, sensor calibration drift, and signal cable insulation breakdown in moisture-rich environments.

Common ACEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ACEC equipment arriving at our workshop.
- ✓Thyristor gate drive circuit failure in ACEC rectifiers — ACEC high-power thyristor rectifiers suffer gate drive failures due to pulse transformer winding shorts, optocoupler degradation, and driver IC burnout from voltage spikes. This is especially common in Indian steel mills with high ambient dust and temperature cycling.
- ✓ACEC controller output stage transistor burnout — In ACEC analogue controllers and regulators, output power transistors fail from thermal runaway, secondary breakdown, or inadequate base drive margin. Inadequate heatsink cleaning in Indian dusty plant environments accelerates thermal failure.
- ✓ACEC soft starter power semiconductor open circuit or leakage — ACEC soft starters lose power semiconductor functionality through gate oxide degradation, junction contamination, or thermal stress from switching transients. Extended operation in high-humidity cement and paper plants accelerates degradation.
- ✓Corrosion and relay contact welding in ACEC control cabinets — ACEC electromechanical relays and contactors in legacy control cabinets suffer contact welding from arc erosion and atmospheric corrosion in coastal and industrial Indian regions. Moisture ingress accelerates failure.
- ✓ACEC process controller measurement input drift and non-linearity — Input buffer amplifiers and analogue-to-digital converter reference stages in ACEC controllers drift from component aging, capacitor dielectric absorption, and reference voltage regulator drift. Long-term operation in thermal cycling environments causes creep.
- ✓ACEC transformer insulation breakdown and primary-secondary winding shorts — Power transformers in ACEC rectifier units fail from insulation degradation due to thermal stress, moisture absorption, and mechanical vibration in Indian rolling mills and metalworking plants. Winding faults create secondary shorts and severe core saturation.

Frequently Asked Questions — ACEC Repairs
Do you repair ACEC equipment anywhere in India?+
Yes. Synchronics repairs the full ACEC product range - thyristor rectifiers, soft starters, industrial controllers, power modules, and legacy control cabinets. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major industrial cities. Repairs are handled at our main facility in Vadodara, Gujarat, with a 7-14 day standard turnaround.
Can Synchronics repair older ACEC thyristor rectifier units still running in my steel mill?+
Absolutely. ACEC thyristor rectifiers are built to last, and many units commissioned in the 1990s and 2000s are still in service across Indian steel and chemical plants. Synchronics specialises in legacy ACEC rectifier repair - we stock replacement thyristors, pulse transformers, and gate drive components, and our engineers have deep knowledge of ACEC's proprietary control circuits. We typically diagnose faults within 48 hours.
What is the typical turnaround time for ACEC soft starter repair?+
Standard repairs for ACEC soft starters take 7-10 working days from receipt. Emergency expedited service is available for critical production lines - we can prioritise diagnosis and repair within 48-72 hours if needed. We test all repaired soft starters on a full-load motor test stand to guarantee performance before return to your facility.
Do you provide warranty on ACEC equipment repairs?+
Yes. All Synchronics repairs come with a 12-month warranty covering parts and labour against manufacturing defects. For critical equipment, we offer extended 24-month warranties and on-site commissioning support to ensure seamless integration back into your production line.
Can Synchronics help with ACEC control cabinet retrofitting or modernisation?+
Yes. Many Indian plants are modernising legacy ACEC control cabinets with modern PLCs, soft starters, and digital regulators. Synchronics offers retrofit consultancy - we assess your existing ACEC cabinet, recommend modern alternatives compatible with your motor and load profiles, and handle full installation and testing at your site.
How do I send my ACEC 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 ACEC 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 ACEC 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 ACEC 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.
