ATS Product Lines We Repair
Our engineers are trained on the full ATS product range. Below are the major product families we service.
Static Transfer Switches (STS)
Ultra-fast static transfer switches used in data centres, hospitals, and telecom networks to transfer load between utility and backup power in milliseconds. Common failures include thyristor failures, gate driver card faults, and voltage sensing circuit degradation.
Automatic Changeover Switches (ACS)
Electromechanical automatic changeover units for facilities lacking static transfer capability. Used extensively in Indian industrial plants and small-to-medium data centres. Prone to contactor coil burn-out, mechanical latching failures, and delay timer circuit faults.
Bypass Isolation Modules (BIM)
Integrated bypass and isolation modules preventing simultaneous paralleling of UPS and mains supply in critical power systems. Repair focus includes relay card intermittency, isolation contactor failures, and synchronisation circuit issues.
Power Distribution Units (PDU)
Monitored and managed PDUs interfacing with ATS systems in data centre and IT infrastructure. Failures include current sensor drift, communication card faults, relay output failures, and firmware corruption.
Transfer Switch Control Modules
Intelligent control and monitoring boards managing STS logic, synchronisation, and fault detection. Common issues: microcontroller crashes, voltage reference instability, relay driver shorts, and firmware upload failures.
UPS Integration Kits (UIK)
Purpose-built interface modules connecting ATS units with major UPS brands (Eaton, Schneider, Cummins) common in Indian industrial setups. Failures include isolation transformer saturation, communication protocol mismatches, and inverter phase-lock circuit instability.

Common ATS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ATS equipment arriving at our workshop.
- ✓Thyristor gate driver failure in STS — Voltage spikes during mains switchover or prolonged operation without thermal management cause gate driver IC failure. Indian industrial plants with poor power quality (frequent surges) experience this more frequently, especially during monsoon seasons when grid disturbances occur.
- ✓Contactor coil burnout in ACS units — Sustained coil voltage above 110% rating or arcing at contactor contacts due to poor maintenance and dust accumulation. Common in Indian textile mills, foundries, and chemical plants where dusty environments accelerate contact degradation.
- ✓Voltage sensing circuit drift in STS control board — Capacitor ageing and reference IC drift cause the STS to detect incorrect supply voltage, triggering nuisance transfers. This is especially problematic in high-temperature Indian industrial environments where ambient temperatures exceed 45°C regularly.
- ✓Relay output card intermittency — Cold solder joints on relay driver outputs and relay coil chatter from insufficient holding current cause intermittent equipment shutdown signals. Vibration and thermal cycling in Indian manufacturing facilities accelerate this failure mode.
- ✓Communication protocol timeout between control module and PDU — Firmware version mismatch, corrupted EEPROM, or EMI-induced CRC errors on the communication bus prevent proper status monitoring. Indian data centres with poor cable shielding and high-power equipment nearby report this frequently.
- ✓Phase lock circuit failure in UPS integration mode — Noise on the voltage reference input or PLL IC instability causes the ATS to lose synchronisation with the mains phase, preventing seamless transfer and triggering backup power activation. Occurs in plants with unstable grid and weak utility earthing.

Frequently Asked Questions — ATS Repairs
Do you repair ATS equipment anywhere in India?+
Yes. Synchronics repairs the full ATS product range — static transfer switches, automatic changeover units, bypass isolation modules, and PDUs. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major industrial cities. All repairs are performed at our 15,000 sq ft facility in Vadodara, Gujarat with same-day turnaround for most faults.
What is the typical repair turnaround time for an ATS static transfer switch?+
For standard STS faults like thyristor failure or control card issues, Synchronics delivers 24-48 hour turnaround including parts replacement, functional testing, and load certification. Critical data centre applications receive priority handling with same-day diagnostics and expedited parts procurement. All STS units are load-tested to 120% rated current before shipment to ensure field reliability.
Can you repair ATS equipment damaged by power surges and lightning?+
Yes. Lightning and mains surge damage is one of the most common ATS failures we repair across Indian industrial zones. Synchronics replaces surge-damaged components (thyristors, control ICs, relay drivers) and installs varistor-based surge suppression on all voltage-sensitive inputs. We also recommend transient voltage suppression devices (TVS diodes) on external signal lines. Post-repair surge immunity testing is mandatory for all units.
Do you stock ATS spare parts or does repair mean waiting for imported components?+
Synchronics maintains inventory of fast-moving ATS components including gate driver cards, control boards, relay modules, thyristor assemblies, contactor coils, and filter capacitors. For obsolete or speciality parts, we leverage vendor relationships to source within 3-5 working days. Critical components are available ex-stock, minimising production downtime for Indian manufacturers and data centre operators.
What warranty and testing do you provide on repaired ATS units?+
All ATS repairs carry 12 months RTB (Return To Base) warranty with 18 months extended warranty available. Every unit undergoes functional test bench validation, thermal cycling (0-55°C), high-voltage stress testing, and load verification before dispatch. We provide detailed test reports and fault analysis documentation — critical for compliance audits in hospitals, data centres, and regulated manufacturing sectors.
How do I send my ATS 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 ATS 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 ATS 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 ATS 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.
