ELTEE PULSITRON Product Lines We Repair
Our engineers are trained on the full ELTEE PULSITRON product range. Below are the major product families we service.
Pulsitron Soft Starters (PST Series)
Electronic soft starting units for three-phase AC induction motors, reducing inrush current and mechanical stress. Common issues include thyristor failure, control card degradation, and capacitor breakdown in high-temperature mill environments.
Pulsitron VFD Motors (PVF Series)
Compact variable frequency drives for speed control and energy optimisation. Frequent failures include IGBT module faults, EMI filter capacitor aging, and firmware corruption due to power surges on Indian industrial grids.
Pulsitron Power Factor Correction (PFC Modules)
Automated reactive power compensation controllers for reducing power factor penalties. Prone to capacitor bank failures, contactor welding, and control relay fatigue in textile spinning mills.
Pulsitron DC Drive Controllers (PDC Series)
Thyristor and SCR-based DC motor control units for sugar factories and metal rolling mills. Typical failures: bridge rectifier failure, firing control circuit malfunction, and heat sink corrosion in humid environments.
Pulsitron Load Commutated Inverters (LCI)
High-power synchronous motor drive systems for cement plants and paper mills. Repair challenges include commutation circuit timing drift, DC link capacitor degradation, and gate driver circuit failures.

Common ELTEE PULSITRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELTEE PULSITRON equipment arriving at our workshop.
- ✓Thyristor short circuit and gate drive failure — ELTEE Pulsitron soft starters and DC drives employ thyristor bridges exposed to high dV/dt transients on Indian industrial power systems. Gate drive circuits degrade due to thermal cycling and moisture ingress, causing loss of commutation control and shoot-through faults.
- ✓Electrolytic capacitor dry-out and dielectric breakdown — ELTEE Pulsitron VFDs and soft starters operate in high-ambient environments typical of Indian textile mills (45-50°C continuous). Aluminium electrolytic capacitors in DC link circuits desiccate prematurely, causing voltage ripple, nuisance faults, and catastrophic arc-over failures.
- ✓Control card microprocessor reset and program corruption — Indian factory power supplies often experience brownouts, phase unbalance, and harmonic distortion that corrupt ELTEE Pulsitron control firmware. Insufficient power supply filtering and lack of watchdog timer margin lead to unexpected processor halts and loss of drive tunning parameters.
- ✓Heat sink thermal fatigue and solder joint cracking — ELTEE Pulsitron power modules experience rapid thermal cycling between IGBTs and attached heat sinks in sugar plant motor duty cycles. Insufficient thermal interface material and mechanical vibration cause cyclic stress on solder connections, leading to thermal resistance increase and junction temperature rise.
- ✓Drive communication loss and parameter read timeout — ELTEE Pulsitron soft starters and VFDs connected to plant SCADA systems over RS485 or Modbus suffer noise-induced frame errors when fieldbus cables run parallel to power cables or lack proper shielding. Corrupted parameter tables render drives inoperable and confuse diagnostic scan.
- ✓Contactor and relay chatter in soft starter bypass circuits — ELTEE Pulsitron soft starters employ mechanical bypass contactors to reduce heat dissipation at steady-state motor speed. Inadequate arc suppression, worn contact surfaces, and phase current imbalance in cement mills cause intermittent opening and closing, generating motor vibration and noise.

Frequently Asked Questions — ELTEE PULSITRON Repairs
Do you repair ELTEE Pulsitron equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full ELTEE Pulsitron soft starter and VFD range — PST series, PVF drives, PFC modules, DC controllers, and LCI systems. We offer same-day pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and across India. Repairs completed in our Vadodara, Gujarat facility with express turnaround (5-10 working days typical).
How does Synchronics repair ELTEE Pulsitron soft starters for textile mills?+
ELTEE Pulsitron soft starters in textile spinning mills endure extreme duty cycles and harsh electrostatic discharge environments. Synchronics performs component-level repair: we test thyristor modules under load, replace failed gate driver ICs, restore control processor firmware, and validate soft-start ramp timing before return. We understand the 4:1 current limiting ratios and acceleration profiles that ELTEE Pulsitron designs use.
What do I do if my ELTEE Pulsitron VFD shows overcurrent fault ERR-07?+
ERR-07 (Overcurrent) in ELTEE Pulsitron PVF drives indicates IGBT short circuit, DC link capacitor voltage sag, or motor phase imbalance. First: measure DC bus voltage (should be 540V-680V for 380V input). Second: check motor phase resistance with multimeter. Third: contact Synchronics — we can diagnose IGBT health via IR thermography, test capacitor ESR, and replace failed modules. Many cases resolve after thermal cycling and capacitor refresh.
Can Synchronics repair ELTEE Pulsitron DC drive controllers used in metal rolling mills?+
Absolutely. ELTEE Pulsitron PDC series DC drives control mill motors requiring smooth speed ramp and high torque. Synchronics specialises in thyristor bridge rectifier testing, firing control circuit calibration, and commutation reactance tuning. We source commutation transformers, replace worn slip rings on shaft encoders, and validate speed stability across full 0-1800 RPM range. Repairs backed by 1-year warranty.
Do you stock original ELTEE Pulsitron spare parts and components?+
Synchronics maintains a curated stock of ELTEE Pulsitron components: thyristor modules (40A-400A ratings), IGBT modules, electrolytic capacitors (450V, 105°C rated), gate driver ICs, and control transformers. For unavailable parts, we source from authorised ELTEE Pulsitron distributors and complete repair within agreed timelines. All replaced components are tested before assembly.
How do I send my ELTEE PULSITRON 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 ELTEE PULSITRON 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 ELTEE PULSITRON 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 ELTEE PULSITRON 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.
