UNIPULSE Equipment We Repair — By Category
UNIPULSE Product Lines We Repair
Our engineers are trained on the full UNIPULSE product range. Below are the major product families we service.
UNIPULSE SMPS Series
Switch-mode power supply units delivering regulated DC output from 5V to 48V for industrial PLCs, servo drives, and control panels. Common failures include blown capacitors, transformer burnout, and PWM controller IC failure under load surge conditions.
UNIPULSE Thyristor Rectifier Modules
Three-phase industrial rectifiers with soft-start and over-current protection for heavy-duty motor control and electroplating applications. Typical faults include thyristor short circuits, commutation failures, and gate-drive circuit damage from surge voltages.
UNIPULSE PWM Controller Boards
Embedded control modules for pulse-width modulation in textile dyeing, printing, and chemical processing. Prone to MOSFET gate failure, microcontroller watchdog resets, and sensor input signal conditioning issues in humid factory floors.
UNIPULSE Industrial UPS Modules
Uninterruptible power supply units for critical process automation and data logging systems in Indian manufacturing plants. Battery charging circuit failures and inverter IGBT module degradation are common under continuous operation.
UNIPULSE DC Power Distribution Panels
Rack-mount or wall-mounted distribution systems with multiple regulated outputs for large industrial automation setups. Faults include relay contact burn-out, bus bar corrosion, and output voltage regulation loss due to aging electrolytic capacitors.
Why Choose Synchronics for UNIPULSE Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on UNIPULSE equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 UNIPULSE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in UNIPULSE equipment arriving at our workshop.
- ✓Output voltage drift and regulation loss — Aging and drying of electrolytic capacitors in the feedback network causes reference voltage instability and poor load regulation. High ambient temperature in Indian manufacturing plants accelerates capacitor degradation.
- ✓Blown input surge protection fuses — Inductive kickback from nearby motor starters and transformer switching in crowded Indian factory switchboards causes transient over-voltage that exceeds UNIPULSE thermal fuse ratings.
- ✓MOSFET gate driver IC failures — Humidity ingress and corrosion of PCB traces in damp textile mill and chemical plant environments causes gate-drive circuit leakage and false switching signals, destroying MOSFET chips.
- ✓Thyristor commutation failures (rectifier modules only) — Harmonic distortion from unfiltered load currents and stray inductance in motor control circuits cause delayed commutation, leading to short-circuit thyristor pairs and repetitive gate-drive pulse losses.
- ✓Watchdog reset loops in PWM controller modules — Microcontroller firmware corruption or sensor noise on analog input channels (typical in electroplating and dyeing shops with RF noise) causes continuous watchdog timer resets and output shutdown.
- ✓Battery charging circuit failure (UPS modules) — Thermal stress on charging control MOSFETs and diodes during high ambient temperatures, combined with contaminated mains supplies in Indian industrial zones, causes charging voltage regulation collapse.

Frequently Asked Questions — UNIPULSE Repairs
Do you repair UNIPULSE equipment anywhere in India?+
Yes. Synchronics repairs the full UNIPULSE product range — SMPS units, thyristor rectifiers, PWM controllers, UPS modules, and distribution panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Surat, and all tier-2 industrial cities. All repairs are done at our 15000 sq. ft. facility in Vadodara, Gujarat, with guaranteed turnaround of 5-7 working days.
What is the warranty on UNIPULSE repairs at Synchronics?+
All repaired UNIPULSE equipment comes with 12-month comprehensive warranty covering parts and labour. We use only OEM-equivalent components and perform full load-bank testing before dispatch. Extended 24-month warranty is available for high-critical industrial applications. Warranty is honored PAN India through our authorized service associates.
Can you repair UNIPULSE SMPS units with corrupted microcontroller firmware?+
Yes, absolutely. If your UNIPULSE SMPS is stuck in boot loops or not responding to input commands, we can recover or reflash the microcontroller using UNIPULSE factory firmware and development tools. Synchronics maintains firmware repositories for all UNIPULSE models and performs full functionality testing on reprogrammed units, including soft-start sequencing and output regulation stability checks.
How quickly can Synchronics diagnose a faulty UNIPULSE power supply?+
Same-day fault diagnosis. Our test bench includes programmable AC load banks, precision digital multimeters, high-resolution oscilloscopes, and thermal imaging cameras. We generate detailed technical reports identifying the root cause (capacitor aging, MOSFET failure, feedback circuit drift, etc.) within 4-6 hours of equipment receipt. Preliminary assessment is communicated to you via email with repair quotation and estimated lead time.
Do UNIPULSE thyristor rectifier modules require line reactors to prevent commutation failures?+
In most Indian industrial settings with variable load transients and motor-intensive nearby equipment, yes. We recommend 3-5% series line reactors to reduce dI/dT stress on gate-drive circuits and prevent false commutation. Synchronics can supply and fit suitable reactors as part of the repair, or advise on external fitment if your switchboard space is constrained. We test rectifiers with and without reactors to confirm stable gate-pulse timing.
How do I send my UNIPULSE 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 UNIPULSE 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 UNIPULSE 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 UNIPULSE 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.
