MAXWELL Equipment We Repair — By Category
MAXWELL Product Lines We Repair
Our engineers are trained on the full MAXWELL product range. Below are the major product families we service.
BOOSTCAP Ultracapacitor Modules
High-power energy storage units for peak load management and ride-through applications in industrial drives and power systems. Common faults include internal cell failure, voltage imbalance across module strings, and electrolyte degradation in hybrid supercapacitor packs.
Power Factor Correction Capacitors
Voltage-stabilization and harmonic-filtering capacitors for industrial AC systems, commonly rated 480V-690V. Failure modes include dielectric breakdown, internal fusing due to surge transients, and loss of capacitance under thermal stress.
Electromagnetic Assemblies and Coils
Custom-wound electromagnets and field coils for industrial machinery, electrical machinery, and motion control systems. Typical repairs involve insulation failure, open or shorted windings, and bearing surface degradation in rotating assemblies.
Why Choose Synchronics for MAXWELL 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 MAXWELL 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 MAXWELL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MAXWELL equipment arriving at our workshop.
- ✓Ultracapacitor cell voltage imbalance in strings — Unequal leakage current across series-connected cells in BOOSTCAP modules causes voltage drift and thermal stress. Manufacturing tolerance variations and external circuit asymmetry accelerate this degradation.
- ✓Capacitor dielectric breakdown and ESR rise — Overvoltage transients from grid surges, inadequate snubber circuits, and thermal cycling in high-ambient Indian industrial environments degrade the dielectric layer in power factor correction units, raising equivalent series resistance (ESR) and reducing filtering efficiency.
- ✓Energy storage module internal fusing failure — Sudden load transients or short-circuit conditions activate the internal thermal fuse in BOOSTCAP packs, opening the circuit and rendering the entire module inert. This is a safety protection that activates under abnormal electrical stress.
- ✓Solenoid winding open-circuit or shorted turn — Insulation breakdown due to voltage spikes, mechanical vibration in Indian automotive and machinery applications, and thermal cycling in high-temperature motor frames cause copper wire fracture or phase-to-frame short in Maxwell electromagnetic assemblies.
- ✓Capacitor can swelling and electrolyte leakage — Aging electrolyte, elevated ripple current above design spec, and ambient temperatures exceeding 50C (common in Indian plant environments) cause gas buildup inside aluminum cans, leading to pressure rupture and chemical leakage.
- ✓Ultracapacitor module reduced energy storage capacity — Manufacturing micro-cracks in supercapacitor electrodes, electrolyte contamination, and long-term self-discharge in offline storage degrade the double-layer capacitance in BOOSTCAP modules, reducing effective energy density below rated Farad specification.

Frequently Asked Questions — MAXWELL Repairs
Do you repair Maxwell equipment anywhere in India?+
Yes. Synchronics repairs the full Maxwell product range — ultracapacitors, power factor correction units, and electromagnetic assemblies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all other cities. Same central facility in Vadodara, Gujarat with 180+ engineers and 30+ years of industrial electronics expertise.
What is the typical turnaround time for Maxwell capacitor repair?+
Standard Maxwell capacitor and power factor correction repairs take 5-7 working days from receipt. Ultracapacitor modules (BOOSTCAP series) require precision cell-level testing, so turnaround is 10-14 days. Expedited same-week repairs are available for critical production downtime; contact our emergency hotline. All repairs include full load testing and OEM compliance certification.
Can you repair Maxwell BOOSTCAP ultracapacitor modules that have voltage imbalance errors?+
Yes. Voltage imbalance in BOOSTCAP strings is one of our most common Maxwell repairs. We measure cell-by-cell voltage, identify failed cells using thermal imaging and DC leakage testing, and replace individual cell packs while maintaining the original module housing and connector geometry. Repaired modules are re-rated and certified to OEM specifications — typically 99-100% recovery of rated Farads.
Do you supply new Maxwell components or only repair?+
Synchronics primarily repairs and restores Maxwell equipment to OEM working condition. For obsolete or unrepairable units, we source genuine Maxwell replacement capacitors, ultracapacitor modules, and electromagnetic assemblies through authorized distributors. We also recommend equivalent third-party energy storage units (e.g., Maxwell-compatible supercapacitor alternatives) if the original part is end-of-life. Contact our sales team for sourcing options.
Do you offer on-site Maxwell repair or commissioning support for Indian plants?+
Yes. For large-scale installations (power plants, steel mills, automotive lines), Synchronics deploys field technicians to perform on-site diagnosis, repair, and re-commissioning of Maxwell capacitor banks and energy storage systems. We coordinate with your maintenance teams, provide spare units during repairs, and document all work with test reports and OEM compliance certificates. Contact us for quotation.
How do I send my MAXWELL 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 MAXWELL 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 MAXWELL 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 MAXWELL 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.
