SUTRON ELECTRONICS Repair Services India

Yes. Synchronics repairs the full Sutron Electronics product range - DC drives, AC variable frequency drives, servo amplifiers, regenerative systems, and process control I/O modules. We offer PAN India door-pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 industrial cities. All repairs are performed at our primary facility in Vadodara, Gujarat, with turnaround times of 5-10 working days for standard faults and emergency same-day diagnostics available.

Sutron DC drive rectifier repairs typically require 4-6 working days at Synchronics. Upon arrival, we perform full rectifier bridge diagnostics, test thyristor triggering circuits, and replace failed diodes or thyristors. For complete rectifier modules, we stock OEM-equivalent replacement units and perform same-day swap-out if damage is identified. We then run the drive on our 50 kW test rig under full load conditions before return shipment.

Synchronics maintains a stocked inventory of high-demand Sutron spares including thyristor modules, IGBT chips, capacitor banks, opto-couplers, relay modules, and encoder connectors. For specialized or obsolete Sutron components, we maintain vendor relationships in Bangalore and Mumbai to source parts within 2-3 days. Critical spares are available on emergency order for same-day courier dispatch to your facility.

Yes, this is a common Sutron DC and servo drive issue we diagnose regularly. Speed hunting typically indicates aging encoder feedback cable, worn mechanical couplings, or PI loop tuning drift. Synchronics inspects the entire speed feedback chain, performs oscilloscope analysis of the tachometer/encoder signal, measures filter capacitor ESR, and recalibrates proportional and integral gains. We validate stable speed regulation across 10-100% load steps on our test stand before return.

Synchronics provides a 12-month warranty on all Sutron Electronics drive repairs covering parts and labor, with 24-hour phone support for fault diagnosis. Extended warranties up to 24 months are available for critical mill and infrastructure applications. All warranty terms explicitly exclude damage from power supply surges, water ingress, and mechanical abuse. We recommend UPS systems and proper input filtering for Sutron equipment operating on Indian grid power.

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 SUTRON ELECTRONICS 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.
