ELECTRIC REGULATOR CORPORATION Repair Services India

Yes. Synchronics repairs the complete ERC voltage regulator product line - servo-controlled units, thyristor power controllers, ferro-resonant transformers, and digital smart regulators. We offer PAN India pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all industrial centers. All repairs are completed at our ISO 9001 certified 180-engineer facility in Vadodara, Gujarat, with guaranteed fast turnaround.

ERC servo-controlled voltage regulators in Indian cotton and polyester mills fail primarily due to dust accumulation in servo motor bearings, causing friction and jerky tap changer movement. The cotton lint, silica dust, and humidity in these environments also corrode brushes and commutator surfaces. Synchronics specializes in complete servo motor overhaul, bearing replacement, and recalibration of the servo response loop to factory specifications. We stock genuine ERC servo components and test on our calibrated load bank.

Absolutely. ERC thyristor-based regulators in Indian welding shops, steel plants, and induction furnace facilities frequently malfunction under high harmonic currents. The SCR gate drive circuits become unstable, firing angles drift, and voltage becomes irregular. Our engineers perform harmonic injection testing, replace gate drive transformer assemblies, reprogram thyristor firing algorithms, and conduct power quality analysis with dedicated instruments to ensure stable regulation under non-linear loads.

Standard ERC servo regulator repairs take 5-7 working days for diagnosis, component repair or replacement, and full factory-simulation testing. Thyristor power controller repairs typically require 4-6 days. Complex ferro-resonant transformer core rewinds may extend to 10-12 days. Synchronics provides daily status updates and can expedite critical repairs for pharmaceutical and semiconductor plants using priority channels. Emergency repairs can be supported with loaner units.

Synchronics provides a 12-month comprehensive warranty on all ERC equipment repairs covering parts and labor. We stock genuine ERC spare parts and use OEM-grade replacement components. Our warranty includes replacement of failed components during the 12-month period, provided the equipment is operated within rated specifications and maintained according to ERC guidelines. Extended 24-month warranties are available for critical installations in pharmaceutical and food processing plants.

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.

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.

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.

Yes. If we cannot repair your ELECTRIC REGULATOR CORPORATION 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.
