DYNASTAT INC Product Lines We Repair
Our engineers are trained on the full DYNASTAT INC product range. Below are the major product families we service.
Dynastat AVR (Automatic Voltage Regulator)
Automatic voltage regulation systems using thyristor switching and magnetic amplifier technology to maintain steady output voltage under load fluctuations. Common issues include thyristor failure, control transformer saturation, and response lag under heavy transient loads.
Dynastat Precision Voltage Controller
Phase-angle control and tap-changing systems for critical machine tool loads and precision manufacturing. Failures typically involve phase-shift circuit degradation, servo motor wear in tap-changer mechanisms, and feedback potentiometer drift.
Dynastat Power Stabilizer Units
Integrated three-phase power conditioning combining voltage regulation, harmonic filtering, and reactive power correction. Common repair needs include capacitor bank degradation, filter inductor shorts, and control module PCB failures.
Dynastat Tap-Changing Transformers
Load-tap-changers with integral voltage control for on-load regulation in distribution and manufacturing environments. Repair challenges include selector switch contact erosion, motor drive assembly wear, and synchronization fault between mechanical and electrical position.
Dynastat Thyristor Control Modules
Solid-state switching and gating modules used as subsystems in Dynastat regulators and stabilizers. Prone to failure from gate-drive circuit degradation, snubber capacitor aging, and thermal cycling stress on solder joints.

Common DYNASTAT INC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNASTAT INC equipment arriving at our workshop.
- ✓Dynastat AVR output voltage drifting or unstable — Feedback potentiometer contamination, worn slider contact, or drift in the error-amplifier IC (typically LM358 or equivalent). Environmental moisture and vibration from factory floors degrade sensor reliability over time.
- ✓Thyristor firing delay or asymmetric phase control — Gate-drive circuit component failure (diode, capacitor, or gate resistor degradation), or phase-shift network capacitor drift. Causes unequal gate pulse timing across thyristor pairs, creating phase imbalance and harmonic distortion.
- ✓Dynastat transformer core saturation and audible hum — Sustained overvoltage, DC bias from rectifier faults, or core material aging. Magnetic amplifier or control transformer develops excessive magnetizing current, causing core heating and acoustic noise.
- ✓Automatic voltage regulator slow response or hunting — Servo motor bearing wear in tap-changer drive, selector-switch mechanical lag, or control loop gain setting degradation. Causes overshooting and oscillation around target voltage, creating instability in sensitive loads.
- ✓Dynastat power stabilizer capacitor bank failure and venting — Electrolytic capacitors aging under continuous duty, elevated ambient temperatures (common in Indian foundries and mills), and harmonic current stress from non-linear loads exceeding design frequency range.
- ✓Load-tap-changer contact erosion and transition voltage spike — Selector switch contacts pit and erode from arcing during on-load tap transitions, especially under heavy reactive loads. Creates contact resistance rise and transient voltage surge during changeover, potentially damaging downstream equipment.

Frequently Asked Questions — DYNASTAT INC Repairs
Do you repair Dynastat Inc. equipment anywhere in India?+
Yes. Synchronics repairs all Dynastat Inc. product families — voltage regulators, automatic voltage controllers, power stabilizers, tap-changing transformers, and thyristor control modules. We offer PAN India door-step pickup service from Mumbai, Delhi, Pune, Bangalore, Hyderabad, Ahmedabad, Surat, and all metro cities. Equipment is transported directly to our factory in Vadodara, Gujarat, where our specialized team conducts full diagnostics and repair.
What is the typical turnaround time for Dynastat AVR repair?+
Standard repair turnaround is 7-10 working days from receipt at our Vadodara facility. For urgent breakdowns, we offer express service (3-5 days) on Dynastat voltage regulators and control modules. Diagnosis report is provided within 24 hours of arrival. All repairs include calibration verification, load-bank testing, and factory-aligned performance certification before return shipment.
Can Synchronics repair Dynastat power stabilizers with digital control modules?+
Yes. Synchronics has expertise in both analog and digital Dynastat stabilizer systems. For digital control module failures, we perform circuit board-level repair (component-level rework), firmware verification, and interface testing with legacy sensor systems. We maintain compatibility with original Dynastat harmonic filtering and reactive power correction algorithms. Full functional testing under three-phase load conditions is conducted post-repair.
How do I know if my Dynastat tap-changer is failing?+
Common warning signs include: audible clicking or grinding noise during voltage transitions, voltage spikes (±5% or higher) during tap changeover, selector-switch contacts arcing (visible through inspection ports), slow response to load changes, or mechanical binding during manual operation. If you observe any of these, contact Synchronics immediately. Our field technician can perform on-site diagnostics and recommend repair vs. replacement. Early intervention prevents downstream equipment damage in your factory.
Do you stock Dynastat replacement components like thyristor modules and control transformers?+
Synchronics maintains working inventory of critical Dynastat replacement parts including thyristor modules (150A-750A range), control transformers, magnetic amplifier cores, and electrolytic capacitor banks rated for high-temperature industrial service. For rare or obsolete Dynastat modules, we source matched equivalents from validated suppliers. Lead time for out-of-stock components is typically 5-7 days. Priority stocking available for high-volume users in textile, steel, and pharma sectors across India.
How do I send my DYNASTAT INC 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 DYNASTAT INC 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 DYNASTAT INC 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 DYNASTAT INC 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.
