ELTEC Product Lines We Repair
Our engineers are trained on the full ELTEC product range. Below are the major product families we service.
ELTEC Frequency Drives (VFD)
Three-phase variable frequency drives ranging from 0.37kW to 400kW for motor speed control and energy optimization. Common faults include thermal overload, capacitor degradation, IGBT module failure, and communication loss on CANopen/Modbus interfaces.
ELTEC Soft Starters
Electronic soft-start controllers for reducing inrush current and mechanical stress on three-phase motors. Failures often involve thyristor short-circuits, temperature sensor faults, logic board corrosion, and loss of phase detection.
ELTEC Energy Management & Monitoring
Networked power analyzers, harmonic monitors, and energy meters for plant-wide electrical auditing. Typical repair issues include damaged voltage/current transformers, corrupted data logging memory, RS485 transceiver faults, and display LCD failures.
ELTEC PLC & Automation Controllers
Compact and modular programmable logic controllers for process automation, pump/compressor sequencing, and HVAC control. Repairs address CPU module failures, input/output card faults, backup battery degradation, and firmware corruption.
ELTEC Power Factor Correction (PFC)
Automatic reactive power compensation units reducing power factor penalties and improving grid stability. Common defects include thyristor module failures, capacitor bank open-circuits, microprocessor resets, and contactor sticking.
ELTEC Human-Machine Interfaces (HMI)
Touchscreen panels and operator interfaces for equipment control and real-time monitoring, with capacitive and resistive display variants. Typical faults include touch sensor unresponsiveness, controller board short-circuits, communication protocol errors, and screensaver memory leaks.

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 ELTEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELTEC equipment arriving at our workshop.
- ✓ELTEC frequency drive thermal shutdown or overheat warning — Heatsink fouling from dust and oil vapor common in Indian mills and foundries; fan bearing seizure; thermal sensor malfunction due to corrosion near moisture-laden air intake.
- ✓ELTEC soft starter thyristor short-circuit or open-circuit — Inrush current surge from undersized reactor coils; contaminated gate drive signals in noisy switch-mode environments; inadequate snubber capacitor sizing on 440V Indian three-phase systems.
- ✓ELTEC energy meter data loss or display blank — Backup lithium battery expiration (common after 4-5 years of use); corrupt EEPROM memory due to sudden power cuts frequent in Indian industrial estates; display backlight LED failure in older models.
- ✓ELTEC PLC CPU module non-responsive or no LED activity — Standby battery voltage degradation; corrupted firmware from power interruption during program upload; watchdog timer reset loop caused by unstable power rail on logic board.
- ✓ELTEC power factor correction capacitor bank imbalance or low kVAr output — Individual capacitor element dry-out or open-circuit in tropical climate environments; manual contactor misalignment; missing or degraded detuning reactor causing harmonic resonance with mill transformer impedance.
- ✓ELTEC HMI touchscreen unresponsive to finger or stylus input — Resistive membrane separation from substrate due to humidity and thermal cycling; controller IC I2C bus timeout; corrupted calibration file in non-volatile memory; false capacitive sensor readings from salt spray corrosion near coastal plants.

Frequently Asked Questions — ELTEC Repairs
Do you repair ELTEC equipment anywhere in India?+
Yes. Synchronics repairs the complete ELTEC product range — frequency drives, soft starters, energy meters, PLCs, HMIs, and power factor correction units. We offer Pan-India pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other cities. All repairs are handled at our Vadodara, Gujarat facility with ELTEC-specific test benches and diagnostic tools.
What is the typical turnaround time for ELTEC frequency drive repair at Synchronics?+
Standard ELTEC VFD repairs (capacitor replacement, thermal sensor fix, firmware reload) take 3-5 working days. Critical repairs requiring IGBT module replacement or custom reprogramming take 7-10 days. We maintain spare ELTEC drive components and firmware libraries on-hand, and offer expedited service for plants in shutdown mode. Emergency same-day diagnostics are available for critical equipment.
Do you repair ELTEC soft starters with CANopen or Modbus interfaces?+
Yes. Synchronics repairs all ELTEC soft starter communication modules including CANopen, Modbus RTU, and Profibus variants. We test communication nodes on networked test rigs, reprogram node IDs, verify baud rate settings, and inspect RS485 transceiver ICs. We also repair ELTEC dual-channel and redundant soft starters used in critical process lines.
Can Synchronics restore data from a failed ELTEC energy meter or PLC?+
Yes. Our engineers use ELTEC proprietary read-out tools to extract calibration data, power history, and configuration from faulty meters and controllers before repair. We backup your settings, perform fault diagnosis, and restore all data after component replacement. This service is essential for compliance audits and maintaining historical energy records required by Indian industrial bodies.
Does Synchronics repair ELTEC equipment with non-standard power supplies or custom firmware modifications?+
Yes. We repair ELTEC drives and controllers even with customer-programmed firmware or non-original power supplies. Our reverse-engineering team can analyze custom code, identify faults, and rebuild or reprogram equipment. We also handle ELTEC units modified for unique voltage ranges or frequency applications common in Indian industrial environments. Contact our technical team with your specific requirements.
How do I send my ELTEC unit for repair?+

What is the cost of repairing a ELTEC 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 ELTEC 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 ELTEC 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.
