ELGAR Product Lines We Repair
Our engineers are trained on the full ELGAR product range. Below are the major product families we service.
ELGAR Smartwave Family (AC Power Sources)
Programmable AC power sources (500VA to 10kVA) used for power quality testing, equipment validation, and manufacturing test benches. Common faults include output voltage regulation failure, frequency lock errors, and internal IGBT module breakdown due to thermal cycling stress.
ELGAR DC Power Supply Range
Regulated DC power supplies (0-600V, 0-100A capability) for industrial process control, battery charging systems, and aerospace component testing. Typical repair cases involve ripple noise issues, output stage transistor failures, and control amplifier drift.
ELGAR Frequency Converter Series
Single-to-three-phase and frequency conversion units (50Hz to 400Hz) critical for defence contractors, aerospace suppliers, and telecom infrastructure in India. Failures include inverter bridge faults, PWM control circuit instability, and reactor component breakdown.
ELGAR UPS and Battery Backup Systems
Uninterruptible power supply units protecting critical industrial and telecom operations. Repair complexity includes battery charger malfunction, inverter stage failures, static transfer switch faults, and main capacitor degradation over time.
ELGAR Measurement and Analysis Instruments
Precision power analysers, harmonic distortion meters, and waveform test equipment used in power quality audits across Indian manufacturing plants. Common issues include sensor calibration drift, display circuit failures, and data logging module faults.
ELGAR Rack-Mount Industrial Power Systems
Heavy-duty 19-inch rackmount AC/DC power conditioning units for industrial cabinets, machine tool controllers, and process automation racks. Prone to thermal management issues, fan failure, and control relay chatter under high-load conditions.

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 ELGAR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELGAR equipment arriving at our workshop.
- ✓Output voltage regulation drift and oscillation — ELGAR feedback control loop capacitor ageing or error amplifier compensation network drift, typically seen after 3000+ operating hours. Thermal cycling in Indian factory environments accelerates capacitor ESR rise and dielectric loss.
- ✓IGBT inverter stage short-circuit or gate drive failure — High junction temperature operation, insufficient thermal management, or gate drive bootstrap capacitor failure in ELGAR Smartwave and frequency converter units. Indian humidity and dust ingress accelerate gate oxide degradation.
- ✓Frequency lock-in failure or unstable phase synchronisation — ELGAR phase-locked loop (PLL) control circuit drift, especially in frequency converter and AC power source units. Input line synchronisation sensor may degrade or PLL compensation network component tolerance shift.
- ✓Static transfer switch (STS) chatter and slow switchover — ELGAR UPS and battery backup systems exhibit STS relay contact pitting or control logic timing mismatch between inverter and mains path. Dust contamination and humidity in Indian data centre environments degrade relay contacts.
- ✓Battery charger current regulation failure or float voltage drift — ELGAR UPS charger stage reference voltage source tolerance shift, temperature compensation thermistor failure, or PWM duty-cycle regulation circuit instability. Aged electrolytic capacitors in charging circuit cause voltage instability.
- ✓Display or control panel LCD/LED malfunction with loss of metering — ELGAR measurement instruments and UPS systems often suffer LCD driver IC failure, backlight LED ageing, or control microprocessor watchdog timeout due to software corruption or EMI in Indian industrial environments.

Yes. Synchronics repairs the full ELGAR product range - AC/DC power sources, UPS systems, frequency converters, and test instrumentation. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are carried out at our central facility in Vadodara, Gujarat, with same-day inspection and rapid turnaround on standard jobs.
What is the typical turnaround time for ELGAR power supply repair?+
Standard ELGAR repairs - such as capacitor replacement, control circuit tuning, or inverter stage refurbishment - are completed within 5-7 working days from arrival at Synchronics. Complex jobs involving custom board rework or long lead-time component sourcing may extend to 2-3 weeks. We provide daily repair status updates and expedite shipping on request to minimise your downtime.
Can Synchronics recalibrate ELGAR test equipment and power analysers to factory standards?+
Yes. Synchronics owns precision calibration equipment and performs full metrological re-certification on ELGAR measurement instruments, power analysers, and harmonic distortion meters. We align voltage, current, and frequency sensors to traceable standards, validate display accuracy, and issue calibration certificates compliant with ISO 9001 and customer audit requirements - critical for automotive OEMs and aerospace suppliers across India.
What is your warranty on ELGAR repairs?+
Synchronics offers a 12-month comprehensive warranty on all repaired ELGAR equipment covering parts and labour for the same fault. We also provide a 30-day money-back guarantee if the repaired unit fails to meet your performance specification upon delivery. Extended 24-month warranty packages are available on critical industrial units.
Do you stock ELGAR replacement components and modules?+
Synchronics maintains an inventory of commonly needed ELGAR components - IGBT modules, capacitor banks, gate drive optocouplers, display panels, and control PCBs - to accelerate repair cycles. For obsolete or hard-to-source items, we work with ELGAR authorised distributors in India and the USA to expedite procurement whilst you wait.
How do I send my ELGAR 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 ELGAR 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 ELGAR 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 ELGAR 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.
