MEL Product Lines We Repair
Our engineers are trained on the full MEL product range. Below are the major product families we service.
MEL Motor Starters & Soft Starters
Heavy-duty AC motor starting systems for induction motors up to 500 kW. Common faults include thyristor bridge failures, gate drive circuit damage, and thermal runaway in soft-start ramp circuits.
MEL Automation Controllers
Panel-mounted relay logic controllers and early PLC-style systems used in textile mills and process plants. Typical issues involve input/output card failures, relay chatter, and firmware memory corruption.
MEL Servo & Position Control Systems
Closed-loop servo drives and position controllers for paper machines, printing presses, and textile looms. Prone to encoder interface failures, feedback signal loss, and servo amplifier thermal stress.
MEL Power Supply Units
Industrial-grade rectified and regulated DC power supplies for control circuits and field devices. Common failures include capacitor ripple degradation, voltage regulation drift, and transformer insulation breakdown.
MEL Industrial Relay Modules
Electromechanical relay banks and stepping switches for machine sequencing and interlocking circuits. Relay contact wear, coil winding insulation failure, and mechanical latch corrosion are typical repair issues.
MEL Measurement & Instrumentation Cards
Temperature, pressure, and flow signal conditioning modules for sugar, textile, and chemical processing plants. Prone to sensor interface circuit failures, ADC conversion errors, and temperature drift in analog stages.
Why Choose Synchronics for MEL Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on MEL equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common MEL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MEL equipment arriving at our workshop.
- ✓MEL soft starter thyristor bridge breakdown — Thyristor modules (SCR pairs) fail due to voltage spikes from motor load transients or phase loss conditions common in Indian industrial power grids with unstable supply and harmonic distortion.
- ✓MEL AC controller relay contact erosion and chatter — Heavy inductive loads in mills and factories cause contact bounce and arc pitting. Over time, contact resistance increases, leading to dropped signals and erratic machine behavior.
- ✓MEL servo drive encoder feedback loss — Incremental encoder cables in harsh mill environments suffer from vibration-induced connector corrosion, insulation degradation, and capacitive coupling noise from high-current motor cables running parallel to encoder signal lines.
- ✓MEL power supply capacitor ripple failure — Electrolytic capacitors degrade due to continuous thermal stress from Indian ambient temperatures (often 40-45°C in factory floors) and harmonic current from non-linear loads, causing ESR rise and voltage sag.
- ✓MEL automation controller firmware memory corruption — Power supply glitches, electromagnetic interference (EMI) from adjacent welding or induction heating equipment, and age-related EPROM degradation cause program memory bit flips or complete loss of stored logic.
- ✓MEL measurement card ADC conversion drift — Temperature variations across the card, component aging, and loose reference voltage trimmer adjustments cause measured signals to drift 2-5% over weeks or months, throwing process control off spec.

Frequently Asked Questions — MEL Repairs
Do you repair MEL equipment anywhere in India?+
Yes. Synchronics repairs the full MEL product range - motor starters, soft starters, automation controllers, servo drives, relay modules, and instrumentation cards across all 17 MEL product families. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Same-day turnaround available for urgent faults, with repairs completed at our 20,000 sq ft facility in Vadodara, Gujarat.
Why should I choose Synchronics for MEL motor starter repair instead of the OEM?+
MEL soft starters and motor control systems often cost 40-50% of replacement price to repair. Synchronics specializes in MEL thyristor bridge replacement, gate drive circuit repair, and soft-start ramp optimization. Unlike generic repair shops, our engineers understand MEL's proprietary design and Indian grid conditions. We offer 2-3 year warranty on thyristor replacements and test your starter against the exact motor load curve before return.
Can Synchronics repair MEL servo drives used on textile looms and paper machines?+
Yes. MEL servo drives (SRV-25, SRV-50, PCS-100 series) are common in Indian textile mills and paper plants. We repair encoder feedback interface failures, servo amplifier thermal stress, and closed-loop control instability. We have spare servo modules in stock and perform full load-test simulation using calibrated motor couplings before release. Critical for looms and paper machines where downtime costs exceed repair investment.
What is the typical repair time for a MEL soft starter fault?+
Standard MEL soft starter repair takes 5-7 working days: 1 day for fault diagnosis and testing, 2-3 days for component sourcing and thyristor replacement (or relay contact cleaning), 2 days for rework and thermal cycling test. Urgent jobs can be expedited to 48 hours if parts are in stock. We provide loaner starters for critical mill operations.
Do you provide spare parts for MEL equipment?+
Synchronics stocks common MEL spare parts including thyristor modules, relay coils, power supply capacitors, encoder connectors, and servo amplifier heat sinks. For obsolete MEL components, we source compatible industrial-grade alternatives that meet or exceed original specs. All parts come with test certificates and are warranted for 2 years.
How do I send my MEL 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 MEL 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 MEL 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 MEL 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.
