AES Product Lines We Repair
Our engineers are trained on the full AES product range. Below are the major product families we service.
AES Modular UPS Systems
Scalable, redundant UPS architecture for data centres and critical facilities. Common issues include battery charger faults, inverter module failures, and parallel bus communication errors requiring module-level diagnostics and replacement.
AES PowerWave Series
High-efficiency true online UPS for industrial manufacturing and process control. Typical repairs involve IGBT rectifier failures, output transformer degradation, and static bypass switch synchronization issues common in older installations.
AES Battery Management Systems
Intelligent battery supervision for extended runtime configurations. Failures include battery cell monitor communication loss, charger equalization circuit faults, and temperature sensor failures affecting discharge control.
AES Static Transfer Switches (STS)
Automatic transfer switching between primary and backup power sources. Common faults: thyristor gate drive failures, zero-crossing detection errors, and control logic processor crashes requiring firmware reload.
AES Rectifier-Inverter Modules
Power conversion stages in modular systems. Issues involve capacitor degradation, gate driver failures on power semiconductors, and PWM controller malfunction requiring bench-level component replacement.
Why Choose Synchronics for AES 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 AES 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 AES Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AES equipment arriving at our workshop.
- ✓Battery Charger Output Voltage Regulation Failure — AES charger feedback circuits and voltage reference modules fail due to thermal stress in high ambient Indian factory environments. Capacitor aging accelerates in hot, humid conditions common in Gujarat, Maharashtra manufacturing regions.
- ✓Inverter Output Transformer Core Saturation — Extended overload operation or harmonic-rich loads from CNC machines and induction furnaces cause core flux saturation in AES output transformers. Imbalanced three-phase loads in Indian textile mills worsen core heating.
- ✓Static Bypass Thyristor Gate Drive Loss — Contamination of AES gate drive optocoupler circuits by industrial dust and thermal cycling causes gate signal loss. Failure in automatic transfer to mains can leave facilities unpowered or dependent on backup power.
- ✓Parallel Bus Communication Timeout in Modular Systems — Noisy industrial environments (from large motor starters, welding equipment) degrade AES modular system inter-module communication buses. Firmware bugs in older AES software also trigger false timeout errors.
- ✓IGBT Rectifier Bridge Short Circuit or Gate Failure — Power semiconductor stress from frequent power transients (common in Indian textile and food processing plants) causes junction degradation or gate oxide breakdown in AES rectifier IGBTs.
- ✓Battery Isolation Contactor Stuck in Open Position — AES battery isolation contactor coils weaken under thermal cycling or develop deposits from high-humidity Indian coastal environments preventing reliable closure. Mechanical wear on contactor armature causes stiction.

Frequently Asked Questions — AES Repairs
Do you repair AES equipment anywhere in India?+
Yes. Synchronics repairs the complete AES UPS product range — rectifiers, inverters, battery chargers, static transfer switches, and modular power systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all metro cities. All repairs carried out at our ISO certified facility in Vadodara, Gujarat. Same-day acknowledgment for critical power system failures.
Can Synchronics repair my AES modular UPS with failed power modules while keeping other modules online?+
Yes. AES modular systems are designed for hot-swap module replacement. Synchronics removes failed rectifier-inverter modules without shutting down your facility, repairs them on our test benches, and reinstalls validated modules. Your parallel redundancy continues protecting your load during the repair window. We test each module individually before reinsertion.
What is the typical repair turnaround time for AES UPS systems at Synchronics?+
Standard AES repairs (battery charger rebuild, inverter filter replacement, bypass contactor service) complete in 3-5 working days. Critical failures (IGBT replacement, transformer winding) require 7-10 days depending on parts availability. We maintain stock of common AES modules and semiconductors. Emergency same-day diagnostics available for metro customers; regional customers receive priority next-day service.
Does Synchronics handle AES firmware updates and configuration changes?+
Yes. Our engineers reprogram AES UPS controllers with manufacturer-approved firmware releases, reconfigure parallel redundancy settings, and update battery test parameters. We provide documentation of all configuration changes and validate system behaviour post-update on our UPS test stand simulating your facility's load profile.
What warranty does Synchronics provide on AES UPS repairs?+
All Synchronics AES repairs include 12 months spare parts warranty and 6 months labour warranty. We guarantee component functionality and system stability post-repair. If an AES module fails within warranty period due to our workmanship, we provide immediate replacement free of charge, including logistics. Extended warranties available for critical infrastructure installations.
How do I send my AES 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 AES 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 AES 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 AES 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.
