EDISON Product Lines We Repair
Our engineers are trained on the full EDISON product range. Below are the major product families we service.
Edison DC Drive Systems
Thyristor-based DC motor drives used extensively in Indian steel, textile, and paper mills. Common issues include thyristor faults, firing circuit failures, and control board degradation from heat and moisture exposure.
Edison Power Transformers and Rectifiers
Industrial-grade transformers and 6-pulse/12-pulse rectifier units for power conversion in manufacturing plants. Failures typically stem from winding insulation breakdown, tap changer issues, and core saturation.
Edison Motor Control Centres (MCC)
Modular switchgear and motor control assemblies used in pump stations, compressor facilities, and process plants across India. Repairs address contactor wear, overload relay calibration drift, and bus bar corrosion.
Edison Voltage Regulators and Stabilizers
Electromechanical and servo-controlled voltage regulation equipment for sensitive manufacturing processes. Common faults include carbon brush wear in servo motors, potentiometer drift, and transformer tap selector failures.
Edison AC Soft Starters and Soft-Start Controllers
SCR-based soft-start devices for motor inrush current reduction in pumping, ventilation, and conveyor applications. Repair challenges include SCR gate drive circuit faults, thermal shutdown sensor failures, and control microprocessor obsolescence.

Common EDISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EDISON equipment arriving at our workshop.
- ✓Thyristor misfire and commutation failure in DC drives — Edison thyristor gates receive weak or delayed firing pulses due to aging capacitors in the firing circuit board or transformer secondary winding shorts. High humidity in Indian industrial plants accelerates gate drive PCB degradation and solder joint corrosion.
- ✓Tap changer mechanism stuck or hunting in voltage regulators — Edison servo voltage regulators experience tap selector coil burnout, carbon contacts oxidation, and mechanical gear backlash from continuous hunting near setpoint. Moisture ingress and salt-air corrosion in coastal Indian facilities accelerate contact degradation.
- ✓Contactor coil chattering and auxiliary contact degradation in MCCs — Edison motor control centre contactors chatter due to loose laminations, worn armature pole faces, and capacitor plague in AC suppression circuits. Indian dusty plant environments deposit conductive particles between contacts, increasing leakage current and heat.
- ✓Winding insulation failure and inter-turn shorts in power transformers — Edison industrial transformers suffer insulation degradation from thermal stress, moisture absorption in windings, and partial discharge activity. Aged paper insulation becomes brittle; epoxy impregnation cracks under vibration and thermal cycling in Indian foundries and forges.
- ✓SCR gate drive circuit failure in soft starters — Edison soft-start controllers experience SCR gate driver IC obsolescence, solder joint cracking from thermal cycling, and optocoupler degradation. Inadequate thermal management in enclosed Indian control cabinets causes cumulative damage to surface-mount components.
- ✓Brush wear and arcing in servo motor of voltage stabilizers — Edison AVR servo motors experience carbon brush shortening from continuous micro-hunting around the regulation setpoint. Abrasive dust in Indian manufacturing plants accelerates commutator surface roughness and brush shedding.

Frequently Asked Questions — EDISON Repairs
Do you repair Edison equipment anywhere in India?+
Yes. Synchronics repairs the complete Edison product range — DC drives, AC soft starters, power transformers, motor control centres, and voltage regulators across all Indian states. We offer same-day or next-day on-site diagnostics and PAN-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and smaller industrial towns. All repairs are handled at our 10,000 sq.ft. facility in Vadodara, Gujarat with a 4-week turnaround guarantee.
Can Synchronics repair my Edison DC drive from a 1990s steel mill installation?+
Absolutely. Edison DC drive systems from the 1980s-2000s are a core competency for Synchronics. We stock hard-to-find components including Edison firing transformers, thyristor modules, and legacy power factor correction capacitors. Even if your drive is obsolete on the market, we restore it to full nameplate performance. Many Indian steel and textile mills continue running Edison DC drives that we have refurbished multiple times — they offer superior reliability compared to replacement.
What is your typical turnaround time for Edison transformer and rectifier repairs?+
Standard repairs (winding inspection, oil analysis, minor tap changer refurbishment) take 7-10 working days. Full rewind and re-impregnation of Edison power transformers typically requires 21-28 days plus testing protocols. Rectifier unit repairs average 10-14 days. We provide daily email updates on progress and perform overnight courier delivery to minimize your downtime. Emergency repairs can be expedited with advance authorization.
Do you offer preventive maintenance contracts for Edison equipment in my manufacturing facility?+
Yes. Synchronics offers customized Edison equipment preventive maintenance packages tailored to your Indian manufacturing environment. We provide quarterly or bi-annual site inspections, thermography surveys, winding resistance testing, oil sampling, and contactor service for motor control centres. Preventive programs reduce catastrophic failures by 70-80% and extend asset life by 5-10 years. Contact our technical team to design a maintenance schedule for your specific Edison installations.
Are Edison thyristor-based drives more reliable than modern variable frequency drives?+
Edison DC drives and soft starters excel in applications requiring smooth low-speed torque, regenerative braking, and installation in harsh dusty or explosive atmospheres common in Indian mills. While VFDs offer energy efficiency, Edison thyristor technology provides superior reliability, easier field repair, and lower electromagnetic interference — critical in legacy installations. Many Indian plant managers retain Edison drives because replacement costs exceed repair benefits over 15+ year equipment lifespans. Synchronics can assess upgrade economics for your specific application.
How do I send my EDISON 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 EDISON 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 EDISON 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 EDISON 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.
