ELETTRONICA SANTERNO Product Lines We Repair
Our engineers are trained on the full ELETTRONICA SANTERNO product range. Below are the major product families we service.
Santerno DC Drives (DC Series)
Closed-loop DC drives for mill duty, crane hoist, and rolling mill applications. Common issues include thyristor firing circuit faults, field loss protection trips, and armature current regulation drift affecting steel and textile mill operations.
Santerno AC VFD Range
Industrial variable frequency drives for AC motor speed control in centrifugal pumps, compressors, and conveyor systems. Typical faults include IGBT module degradation, DC bus capacitor aging, and gate driver circuit failures.
Regenerative Control Units
Power regeneration modules for hoisting and braking duty cycles in mining and material handling. Repair focuses on thyristor stack replacement, brake resistor faults, and commutation circuit issues.
Thyristor Converter Modules
Six-pulse and twelve-pulse rectifier modules for continuous duty applications. Common failures include gate circuit isolation breakdown, cooling fan malfunction, and phase-fired control instability.
Control and Protection Boards
PCB assemblies for current sensing, voltage regulation, and fault relay logic. Typical repairs include electrolytic capacitor replacement, relay contact cleaning, and signal conditioning circuit rework.

Common ELETTRONICA SANTERNO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELETTRONICA SANTERNO equipment arriving at our workshop.
- ✓Thyristor gate trigger circuit malfunction — Optocoupler degradation or gate resistor open circuit in Santerno DC drives, causing erratic firing pulses and armature current instability. Common in humid Indian industrial environments where moisture ingress accelerates component aging.
- ✓DC bus capacitor aging and voltage ripple increase — High ambient temperature operation in cement plants, foundries, and rolling mills degrades electrolytic capacitor dielectric. This increases input ripple and triggers overvoltage protection faults in Santerno VFDs and DC drives.
- ✓IGBT module thermal fatigue and solder joint cracking — Repeated thermal cycling in Santerno AC drives due to inadequate heat sink cooling or ambient temperature swings. Causes intermittent short circuit faults and gradual loss of switching performance in mill and pump applications.
- ✓Field loss protection nuisance trips — Sensor connection intermittency or regulator IC drift in Santerno DC drive field circuit. Causes repeated shutdown in paper mill unwinder and coil winding applications, reducing production uptime.
- ✓Regenerative braking resistor overheating and open circuit — Undersized resistor for continuous braking duty or cooling fan failure in Santerno regenerative modules used in mine hoists and material handling. Thermal runaway leads to resistor open circuit.
- ✓Phase-fired control instability and firing angle drift — Ramp generator capacitor leakage or comparator IC offset in Santerno converter control boards. Results in poor current regulation and harmonic distortion, affecting synchronous motor starting in textile mills.

Frequently Asked Questions — ELETTRONICA SANTERNO Repairs
Do you repair Elettronica Santerno equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete Elettronica Santerno product range - DC drives, AC VFDs, regenerative modules, thyristor converters, and control boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all other major cities. All repairs are performed at our 180-engineer facility in Vadodara, Gujarat.
What is the typical turnaround time for Santerno DC drive repair?+
Most Santerno DC drive repairs are completed within 3-5 working days from receipt. Simple issues like optocoupler replacement take 24-48 hours. Complex failures requiring PCB rework or thyristor module replacement may extend to 7 days. We provide daily repair status updates and express turnaround options for critical mill production scenarios.
Can you repair Santerno VFDs with IGBT module failure?+
Yes. Synchronics specializes in IGBT module repair for Santerno AC drives. We perform micro-section analysis to diagnose solder joint cracking, reballing using controlled reflow, and thermal cycling testing. If module replacement is needed, we source genuine equivalents and perform gate driver testing before dispatch. All repairs include 12-month warranty.
Why do Santerno drives fail in Indian cement and steel plants?+
Hostile industrial environments - high ambient dust, temperature swings, voltage transients from shared power supplies, and moisture ingress - accelerate component aging in Santerno equipment. Electrolytic capacitors age faster at 40-50 degree ambient. Synchronics addresses these root causes by using industrial-grade replacement components, adding thermal management, and applying protective conformal coating to exposed PCBs.
Do you provide preventive maintenance for Santerno regenerative modules?+
Absolutely. Synchronics offers quarterly PM schedules for Santerno regenerative units used in mine hoists and cranes. We perform thermal imaging to detect cooling fan degradation, measure resistor resistance and temperature rise under load, test thyristor forward voltage, and inspect connector corrosion. Preventive maintenance reduces unexpected downtime by 40-60% in critical applications.
How do I send my ELETTRONICA SANTERNO 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 ELETTRONICA SANTERNO 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 ELETTRONICA SANTERNO 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 ELETTRONICA SANTERNO 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.
