HIND RECTIFIERS LTD Equipment We Repair — By Category
HIND RECTIFIERS LTD Product Lines We Repair
Our engineers are trained on the full HIND RECTIFIERS LTD product range. Below are the major product families we service.
Thyristor Power Modules (TPM Series)
High-current thyristor rectifier modules for DC power supply applications in electroplating, anodizing, and metal treatment. Common failures include thyristor junction breakdown, gate circuit faults, and heatsink thermal issues under continuous load.
Custom DC Power Supply Units (CDPS Range)
Transformer-based rectifier systems with built-in SCR control for variable DC output regulation. Prone to core saturation, winding insulation failure, and control board circuit degradation in high-temperature factory environments.
Rectifier Control and Triggering Systems (RCT Series)
Gate-drive and phase-control electronics for thyristor commutation and firing angle adjustment. Susceptible to capacitor dry-out, optocoupler degradation, and noise-induced firing circuit malfunction in industrial EMI environments.
Industrial Transformer and Bridge Assembly (ITBA Series)
Diode and thyristor bridge assemblies with power transformers for high-amperage rectification in heavy industrial processes. Failures include transformer winding faults, solder joint cracking, and diode avalanche breakdown under fault conditions.
Regenerative Rectifier Modules (RRM Series)
Advanced bi-directional rectifier systems for hoist, crane, and rolling mill applications requiring energy recovery. Common issues are commutation failures, overvoltage stress on IGBTs, and control synchronization errors.

Common HIND RECTIFIERS LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HIND RECTIFIERS LTD equipment arriving at our workshop.
- ✓Thyristor junction short-circuit and module failure — Hind Rectifiers thyristor modules fail due to overcurrent transients, inadequate gate drive pulse width, or thermal cycling stress in foundry and electroplating plants. Junction thermal stress and metallurgical defects accelerate short-circuit mode.
- ✓Rectifier transformer core saturation and overheating — Hind Rectifiers power transformers saturate when input DC ripple frequency is too high or transformer tap settings are incorrect for local supply voltage variations. Core loss heating can exceed 80°C without adequate cooling.
- ✓Gate-drive circuit optocoupler failure and loss of firing pulses — Hind Rectifiers RCT control boards use optocouplers that degrade in high-humidity foundry and chemical plant environments. Coupling efficiency drops, causing weak or missing thyristor gate trigger signals and uncontrolled rectifier output.
- ✓Rectifier bridge diode reverse-recovery failure under transient load — Diodes in Hind Rectifiers ITBA bridge assemblies fail when load current switches rapidly (common in crane, rolling mill, and spot-weld applications). Reverse-recovery current spike causes junction avalanche and thermal runaway.
- ✓Solder joint cracking and intermittent electrical contact in power connections — Hind Rectifiers bridge assemblies and transformer primary terminals experience vibration-induced solder fatigue in rolling mills, forging presses, and metal stamping facilities. Thermal cycling from load transients accelerates crack growth.
- ✓Control board voltage regulator dropout and unstable DC output — Hind Rectifiers CDPS DC regulation relies on precision voltage reference circuits that drift or fail in electrical noise-rich environments. Electroplating process faults and AC supply disturbances cause voltage reference IC failure.

Frequently Asked Questions — HIND RECTIFIERS LTD Repairs
Do you repair Hind Rectifiers equipment across India?+
Yes, absolutely. Synchronics repairs the complete Hind Rectifiers product range — thyristor modules, DC power supplies, rectifier control boards, and bridge assemblies. We offer door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, and all Indian cities. All repair work is completed at our Vadodara facility and shipped back within 7-10 working days.
What is the typical turnaround time for Hind Rectifiers thyristor module repair?+
Thyristor module diagnosis takes 24-48 hours. If we confirm internal junction damage, we source matched SCR pairs and rebuild the module within 5-7 days. Gate-drive circuit repairs typically complete within 3-4 days. We maintain a stock of common Hind Rectifiers component replacements to avoid extended delays. Synchronics provides express turnaround for critical electroplating and metal processing plants running 24/7 shifts.
How do I know if my Hind Rectifiers rectifier transformer needs rewinding?+
Common signs include overheating above 70°C under normal load, reduced DC output voltage, and high core saturation current. Synchronics performs insulation resistance testing, tan-delta analysis, and core loss measurement to determine if rewinding is necessary. Many transformer failures can be reversed by tap adjustment or cooling system upgrades. We advise customers before recommending full rewind.
Can Synchronics repair Hind Rectifiers equipment with obsolete thyristor types?+
Yes. Even if your Hind Rectifiers module uses 1980s-1990s thyristor types no longer manufactured, Synchronics sources modern functional equivalents with matching voltage and current ratings. We test compatibility and apply matching gate-drive adjustments. This approach extends equipment life by 10-15 years at lower cost than new unit purchase — critical for Indian foundries and steel plants with limited capex budgets.
What warranty does Synchronics offer on Hind Rectifiers rectifier repairs?+
All repaired Hind Rectifiers equipment receives a 12-month comprehensive warranty covering labor and parts. We guarantee functional performance at original specifications and provide 24/7 technical support for Indian customers. For mission-critical electroplating lines and rolling mills, we offer extended 24-month warranty on thyristor modules and transformer work.
How do I send my HIND RECTIFIERS LTD 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 HIND RECTIFIERS LTD 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 HIND RECTIFIERS LTD 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 HIND RECTIFIERS LTD 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.
