DOMINION SYSTEMS Product Lines We Repair
Our engineers are trained on the full DOMINION SYSTEMS product range. Below are the major product families we service.
PowerGuard UPS Control Module
Dominion's intelligent UPS management and battery backup controllers used in critical power applications. Common repairs include failed microprocessor units, battery charging circuit faults, and inverter output stage failures causing load shedding or inability to switch to backup power.
DominiControl Power Distribution Units
Advanced electrical power distribution and load-switching controllers for industrial plants and data centres. Typical faults include relay driver failures, voltage regulation circuit breakdowns, and communication board malfunctions affecting real-time load monitoring.
VoltSync Stabilization Systems
Automatic voltage regulation and power quality management equipment for Indian manufacturing plants prone to grid fluctuations. Common issues include sensor calibration drift, thyristor gate drive failures, and output transformer protection circuit faults.
NetSense Power Monitoring Module
Ethernet-enabled power monitoring and analytics controllers for Industry 4.0 integration. Repair needs include network interface failures, data logging memory corruption, and analog input conditioning circuit breakdowns affecting plant energy audits.
Guardian Switchgear Logic Controller
Medium-voltage switchgear protection and control electronics used in power distribution substations. Typical failures involve protective relay circuit faults, trip coil driver failures, and oscillator instability in timing circuits.

Common DOMINION SYSTEMS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOMINION SYSTEMS equipment arriving at our workshop.
- ✓PowerGuard UPS fails to switch inverter — Dominion Systems inverter output contactor driver circuit fails due to aged electrolytic capacitors or optoisolator burnout. This prevents the UPS from transitioning to battery backup when grid power is lost, leaving critical loads unprotected.
- ✓DominiControl rapid load shedding cycles — Dominion's voltage sensing circuit accumulates calibration drift over time, causing the controller to misinterpret incoming voltage levels. This triggers false over/under-voltage alarms leading to unintended load disconnection and process interruptions in Indian manufacturing plants.
- ✓VoltSync stabilizer produces harmonic distortion — Dominion Systems thyristor gate drive circuit develops timing skew or optoisolator coupling degrades, causing asymmetric firing angles. This creates even-order harmonics (primarily 2nd and 4th harmonics) that degrade power quality and equipment lifespan in Indian industries.
- ✓NetSense module network connectivity lost — Dominion's Ethernet interface controller experiences corrupted firmware or RJ45 connector solder joint fractures from thermal cycling in Indian climates. Data transmission to SCADA systems fails, blinding plant management to real-time power consumption metrics.
- ✓Guardian Switchgear protective relay malfunction — Dominion's relay coil driver suffers from failed gate drive transistor or protective fuse open-circuit, preventing relay energization. This disables phase protection logic, risking transformer burnout or uncontrolled feeder faults in medium-voltage substations across India.
- ✓PowerGuard battery charging circuit undercharges — Dominion Systems charger circuit develops compensation network drift or charge pump supply fails, causing insufficient float voltage (typically 2.2-2.3V per cell instead of required 2.27-2.35V). Battery backup time degrades progressively, risking sudden power loss during outages.

Frequently Asked Questions — DOMINION SYSTEMS Repairs
Do you repair Dominion Systems equipment anywhere in India?+
Yes. Synchronics repairs the complete Dominion Systems product range—UPS controllers, power distribution modules, voltage stabilizers, and switchgear logic systems. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are completed in our Vadodara, Gujarat facility with full technical accountability and turnaround guarantees.
What is the typical repair turnaround for Dominion Systems PowerGuard UPS modules?+
Synchronics completes PowerGuard UPS controller repairs in 5-7 working days for standard faults (capacitor replacement, optoisolator swap, firmware reprogramming). Critical infrastructure cases receive priority diagnostics within 24 hours. We maintain stock of common Dominion Systems replacement components—power transistors, gate drive ICs, and capacitor modules—to minimize downtime for Indian industrial customers.
Can Synchronics repair Dominion Systems equipment with corrupted or locked firmware?+
Yes. Synchronics holds Dominion Systems technical documentation including bootloader sequences for PowerGuard, DominiControl, and NetSense modules. We can securely erase and reflash controller firmware using validated Dominion factory images. For legacy models where original firmware is unavailable, our engineers reverse-engineer functional code based on system behaviour and Dominion's published protocols. All repaired equipment undergoes full functional verification before return.
Does Synchronics offer preventive maintenance for Dominion Systems switchgear installations?+
Yes. Synchronics provides on-site preventive maintenance contracts for Guardian Switchgear Logic Controllers and medium-voltage distribution equipment. Our field engineers perform quarterly relay coil testing, thermal imaging of power connections, and firmware health checks. We identify capacitor aging and optoisolator degradation before failures occur, reducing unplanned outages in Indian power distribution networks.
What warranty do you provide on Dominion Systems repairs?+
Synchronics provides 12 months full parts and labour warranty on all Dominion Systems repairs. If equipment fails due to repair workmanship within the warranty period, we repair or replace free of cost. For critical power applications, we offer extended 24-month warranties with on-site 4-hour response service across major Indian metropolitan areas.
How do I send my DOMINION SYSTEMS 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 DOMINION SYSTEMS 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 DOMINION SYSTEMS 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 DOMINION SYSTEMS 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.
