AJS POWER SOURCE Product Lines We Repair
Our engineers are trained on the full AJS POWER SOURCE product range. Below are the major product families we service.
AJS Servo Voltage Stabilizers (SVS)
Electro-mechanical servo stabilizers protecting machinery from voltage fluctuations. Common faults include servo motor failures, carbon brush wear, control relay sticking, and auto-start circuit malfunction in dusty factory environments.
AJS Static UPS Systems
Solid-state uninterruptible power supplies with IGBT inverters and intelligent battery management. Typical repair issues: capacitor bank failures, gate driver IC burn-out, battery charger malfunction, and MOSFET short circuits due to thermal stress.
AJS Rotary UPS Units
Motor-generator based backup systems for high-load industrial applications. Common defects include motor bearing wear, generator output regulator failure, brake mechanism sticking, and field coil insulation breakdown.
AJS Power Conditioning Modules
Rectifier modules, battery charger PCBs, and SMPS units for industrial control systems. Frequent failures: transformer primary winding open circuit, filter electrolytic capacitor dry-out, PWM IC degradation, and transformer core saturation.
AJS Control and Monitoring Cards
Digital microcontroller-based PCBs for automatic voltage control, load sensing, and fault protection. Repair focuses on: relay contact corrosion, optocoupler failure, analog sensor interface faults, and firmware corruption in EEPROM chips.

Common AJS POWER SOURCE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AJS POWER SOURCE equipment arriving at our workshop.
- ✓Servo stabilizer output voltage unstable or drifting — AJS servo motor carbon brushes worn, creating poor electrical contact, or servo feedback potentiometer damaged from dust ingress common in Indian textile mills and foundries. Servo control relay contacts also corroded by moisture and industrial pollutants.
- ✓UPS inverter producing no output or weak AC voltage — AJS IGBT gate driver ICs fail due to transient voltage spikes during mains switchover, or IGBT modules themselves develop short circuits from repeated thermal cycling in non-air-conditioned Indian plant environments. Bootstrap capacitors also dry-out in high-temperature conditions.
- ✓Battery charger not charging or overcharging batteries — AJS charger control IC (typically TL494 or UC3842) drifts out of calibration, or shunt regulator transistor fails in regulation circuit. Opto-isolator may fail breaking feedback loop, causing uncontrolled charging voltage in Indian humidity and temperature extremes.
- ✓Servo stabilizer auto-start circuit not engaging or stalling — AJS auto-start relay coil open due to repetitive on-off cycling in plants with frequent power cuts, or soft-start thermistor thermally damaged. Control timer IC (NE556 or similar) may time out incorrectly, preventing motor ramp-up sequence.
- ✓UPS displaying fault codes or entering alarm state repeatedly — AJS monitoring PCB sensor interface degraded - temperature, voltage, or current sensing ICs producing erratic signals. Firmware EEPROM corruption causes false alarm triggering. Dust accumulation on sensor connectors common in Indian cotton textiles, pharmaceuticals, and food processing facilities.
- ✓Stabilizer servo motor not responding or running only in one direction — AJS servo motor reversing contactor stuck due to carbon dust, or starting capacitor failed preventing motor field winding excitation. Motor rotor may be seized from bearing rust and lubricant breakdown in coastal and humid Indian regions.

Frequently Asked Questions — AJS POWER SOURCE Repairs
Do you repair AJS Power Source equipment anywhere in India?+
Yes. Synchronics repairs the complete AJS Power Source product range - servo voltage stabilizers, static and rotary UPS systems, rectifier modules, and control PCBs. We offer PAN-India door pickup service from Mumbai, Delhi, Pune, Chennai, Hyderabad, Kolkata, Ahmedabad, and all metro cities. Equipment is transported to our fully equipped repair facility in Vadodara, Gujarat, where our specialist engineers complete diagnostics and repair within 3-5 working days on most AJS equipment.
What is the typical turnaround time for AJS stabilizer repair at Synchronics?+
For routine AJS servo stabilizer repairs like brush replacement, relay contact cleaning, and control circuit PCB replacement, turnaround is 2-3 working days. Complex repairs involving servo motor bearing replacement or complete IGBT inverter module replacement may take 5-7 working days. Emergency same-day fault diagnosis is available for critical production scenarios. We keep common AJS spare modules (servo motors, capacitor banks, relay cards) in stock for rapid repair turnaround.
Why does my AJS servo stabilizer have voltage oscillation at the output?+
AJS servo stabilizer voltage oscillation usually indicates servo motor brush wear or servo potentiometer tracking problem. The servo feedback loop cannot maintain stable output regulation. Synchronics inspects carbon brush condition, measures servo motor resistance, and recalibrates servo potentiometer track using precision test equipment. If brushes are worn, we replace with OEM brushes sourced directly from AJS suppliers. Output is then stabilized to within 2% accuracy.
Can Synchronics supply replacement parts for AJS Power Source equipment?+
Yes. Synchronics maintains an inventory of OEM and equivalent replacement parts for AJS Power Source - IGBT modules, gate driver ICs, electrolytic capacitors, servo motors, relay contactors, and control PCBs. For obsolete AJS components no longer in production, our engineers perform careful cross-reference matching with compatible alternatives and test under load conditions. We provide warranty on parts and labor for all repairs.
Does AJS Power Source provide technical support for repairs at Synchronics?+
AJS Power Source schematic diagrams, service bulletins, and technical specification sheets are available to our engineers through our service partnership network. For difficult faults or design issues specific to newer AJS product models, we coordinate directly with AJS technical support in India to ensure repair accuracy and maintain equipment reliability. Our engineers are also trained and certified for AJS equipment repair and installation.
How do I send my AJS POWER SOURCE 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 AJS POWER SOURCE 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 AJS POWER SOURCE 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 AJS POWER SOURCE 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.
