SUDARSHAN ELECTRONICS Equipment We Repair — By Category
SUDARSHAN ELECTRONICS Product Lines We Repair
Our engineers are trained on the full SUDARSHAN ELECTRONICS product range. Below are the major product families we service.
Sudarshan Power Factor Correction (PFC) Units
Automatic capacitor-based systems for reactive power management and harmonic correction. Common failures include capacitor degradation, thyristor trigger circuit faults, and ammonia contaminant ingress affecting dielectric strength in tropical climates.
Sudarshan Soft Starters (SSS Range)
Electronically-controlled motor starting units reducing inrush current and mechanical stress. Typical faults: power thyristor short-circuit, cooling fan bearing wear, and control PCB microcontroller memory corruption from voltage transients.
Sudarshan Automation Control Panels
Customized industrial control enclosures with integrated PLC logic, relay modules, and HMI touchscreen interfaces. Repair common issues: relay contact welding, PLC input/output card failures, and temperature-induced PCB solder joint cracking.
Sudarshan VFD Drives (Variable Frequency Drives)
Vector-control AC drives for motor speed regulation and energy efficiency. Problems include IGBT switching failure, DC bus capacitor ripple increase, EMI filter inductor saturation, and firmware version incompatibility with legacy motors.
Sudarshan Switchgear and Distribution Units
Medium-voltage switchboards and LT distribution panels for power management. Faults arise from contact erosion in vacuum contactors, earth fault detection relay desensitization, and moisture ingress in enclosure gaskets.

Common SUDARSHAN ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in SUDARSHAN ELECTRONICS equipment arriving at our workshop.
- ✓Capacitor bank swelling and liquid leakage — Sudarshan PFC units operate in high-temperature environments (40-50°C ambient common in Indian plants). Aluminum electrolytic capacitors used in the filter stage degrade, causing dielectric breakdown and electrolyte leakage that damages adjacent resistors and PCB traces.
- ✓Soft starter thyristor gate drive circuit failure — Sudarshan soft starters employ gate-turn-off (GTO) thyristors in bridge configuration. Transient voltage spikes from motor switching and poor grounding in Indian factory installations degrade the opto-isolator chips in the gate drive circuit, causing uncontrolled thyristor conduction.
- ✓Control panel relay contact welding — In textile mills and sugar plants, high-frequency contactor cycling (10-15 switches per minute) combined with inadequate arc suppression causes silver contact fusion. Sudarshan panels sometimes lack MOV or diode arc suppression on inductive loads, accelerating contact degradation.
- ✓VFD IGBT module thermal shutdown cycling — Sudarshan VFD drives in foundry and steel rolling applications see motor currents near nameplate limits. Cooling fan clogging from iron oxide dust is endemic in Indian steel plants, causing IGBT junction temperatures to exceed 125°C and trigger repeated thermal shutdowns.
- ✓Switchgear earth fault relay desensitization — Sudarshan 6.6kV and 11kV switchboards use Rogowski coil-based earth fault detection. Excessive harmonic currents (5th and 7th harmonics typical in VFD-heavy plants) and ferrous dust settled on the coil core reduce CT signal amplitude, causing relay to ignore genuine earth faults.
- ✓PLC program memory corruption after power transients — Sudarshan control panels integrate economy-grade PLCs without battery-backed RAM. Lightning strikes and induction motor soft-starter transients cause supply-side voltage fluctuations exceeding ±10% nominal. This corrupts the stored program in flash memory, halting production until reprogramming.

Frequently Asked Questions — SUDARSHAN ELECTRONICS Repairs
Do you repair Sudarshan Electronics equipment anywhere in India?+
Yes. Synchronics repairs the full Sudarshan Electronics product range — soft starters, PFC units, VFDs, automation control panels, and switchgear. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Belgaum, and all other industrial cities. All equipment is serviced in our Vadodara, Gujarat facility and returned fully tested.
Can you repair Sudarshan VFD drives that have IGBT module failures?+
Absolutely. IGBT module failures are one of the most common VFD faults we encounter. Synchronics carries stock of IGBT modules compatible with Sudarshan SVF series (5kW to 75kW), tests drive output stage with precision load banks, and confirms vector control loop stability before handover. We provide a 12-month warranty on IGBT replacement.
What is the typical turnaround time for Sudarshan power factor correction unit repair?+
For Sudarshan PFC units with capacitor bank or thyristor faults, typical turnaround is 5-7 working days. Surge-damaged control PCBs requiring component-level repair may take 10-14 days. We offer express 48-hour diagnostic service if you need urgent fault identification. Synchronics maintains buffer stock of Sudarshan PFC spare parts to accelerate repair.
Do you test Sudarshan soft starters under load before return?+
Yes, essential for soft starters. After repair, Synchronics performs isolated gate drive voltage testing, thyristor dv/dt stress testing, and full load commissioning trials using our 45kW DC load bank. We verify ramp-up time, current limiting, and emergency stop response matches Sudarshan factory specifications. Test reports are provided with every soft starter.
Can you recover the program from a Sudarshan PLC that lost memory due to power failure?+
If the PLC flash memory is not completely erased, Synchronics can often recover the program using EEPROM readback tools and reverse-engineer missing logic segments from relay wiring diagrams. For complete memory loss, we reprogram the PLC from your original source code or rebuild logic from control panel documentation. This typically takes 7-10 days for complex automation panels.
How do I send my SUDARSHAN ELECTRONICS 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 SUDARSHAN ELECTRONICS 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 SUDARSHAN ELECTRONICS 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 SUDARSHAN 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.
