AULT Equipment We Repair — By Category
AULT Product Lines We Repair
Our engineers are trained on the full AULT product range. Below are the major product families we service.
AULT Power Supply Units (Industrial PSU)
Ruggedised DC and AC-DC power supplies for industrial automation, telecom, and cabinet integration. Common issues include capacitor degradation, rectifier failures, and thermal management problems in high-temperature plant environments.
AULT Rack Mount Power Systems
Multi-output industrial power conversion systems for 19-inch rack installations. Repair challenges include redundancy circuit failures, fan motor burnout, and voltage regulation drift.
AULT Telecommunications Power Units
Telecom-grade PSU systems for central office and remote site installations across Indian telecom networks. Common faults include battery backup circuit failures and load sharing relay failures.
AULT Field Mounted Power Converters
Compact AC-DC converters for industrial field installations and process control cabinets. Issues typically involve conformal coating breakdown and connector corrosion in humid Indian industrial environments.
AULT DC-DC Isolation Modules
Isolated DC-DC converters for multi-voltage rail systems in automation and control applications. Repair focus includes transformer winding shorts, output capacitor ESR rise, and isolation barrier degradation.
Why Choose Synchronics for AULT Repairs?

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 AULT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AULT equipment arriving at our workshop.
- ✓Electrolytic capacitor dry-out and ESR rise — AULT power supplies operate in hot Indian manufacturing environments (35-45°C ambient). Aluminium electrolytic capacitors degrade rapidly, increasing equivalent series resistance (ESR) and reducing filtering efficiency, leading to ripple voltage increase and output instability.
- ✓Rectifier diode bridge failure and heat damage — AULT power supplies use silicon rectifier bridges that fail under transient load spikes common in Indian industrial grids. Single diode failure cascades to bridge short-circuit, causing excessive heat and secondary component damage.
- ✓Output voltage regulation drift and load instability — AULT feedback divider networks and reference circuits degrade due to humidity and temperature cycling in tropical Indian climates. Resistor drift and reference IC aging cause output voltage to creep outside specification (typically ±2% tolerance).
- ✓Thermal shutdown and fan motor failure — AULT PSU thermal sensors and DC fan motors fail in high-dust Indian plant environments. Fan bearings seize, reducing airflow and triggering false thermal shutdowns. Dust accumulation on heatsinks adds thermal resistance.
- ✓Connector corrosion and intermittent power loss — AULT units installed near chemical plants or humid locations experience corrosion on gold-plated connector pins. Salt air and moisture cause intermittent contact resistance, resulting in voltage sag and intermittent shutdown events.
- ✓PWM controller IC oscillation and frequency drift — AULT switching power supplies use PWM ICs that oscillate incorrectly when compensation network capacitors lose capacitance. Oscillation frequency drift causes non-standard ripple patterns and efficiency loss in multi-output systems.

Frequently Asked Questions — AULT Repairs
Do you repair AULT power supplies anywhere in India?+
Yes. Synchronics repairs the complete AULT product range — industrial PSU units, rack-mount power systems, telecom power units, and DC-DC converters. We offer PAN India door pickup and logistics from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major cities. All repairs are performed at our central facility in Vadodara, Gujarat with full test reporting.
What is the typical turnaround time for AULT power supply repair?+
Standard repairs complete in 5-7 working days after arrival. Urgent repairs (output voltage trim, fan replacement, capacitor swap) are completed in 2-3 days. We provide rapid diagnostics within 24 hours and send daily progress updates. Express TSA (Technical Service Agreement) customers receive priority queue and same-week turnaround on 90% of failures.
How do you test AULT PSU reliability after repair?+
Synchronics performs 100% functional testing including no-load and full-load operation at 25°C and 50°C, 8-hour burn-in under worst-case conditions, ripple and noise measurement (oscilloscope), load transient response testing, and thermal stability verification. All units are tested with representative loads and thermal cameras to confirm heatsink performance matches original specifications.
Can you repair AULT telecommunications PSU units used in Indian telecom networks?+
Yes, we specialise in AULT TPS-48 and TPS-60 telecom power units. Common repairs include rectifier module replacement, battery backup circuit restoration, load-sharing relay troubleshooting, and fan pack overhaul. We maintain spare battery backup modules and test under telecom-standard 48V nominal conditions. We provide DOC (Declaration of Conformance) for telecom operator compliance.
What warranty do you provide on AULT power supply repairs?+
All AULT repairs carry 12-month comprehensive warranty covering parts and labour. We warrant against manufacturer defects and premature component failure. Consumables (thermal grease, conformal coating) are refreshed as part of warranty. In-warranty repeat failures receive free return shipping and priority re-repair at no charge.
How do I send my AULT 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 AULT 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 AULT 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 AULT 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.
