DBT Product Lines We Repair
Our engineers are trained on the full DBT product range. Below are the major product families we service.
DBT Power Distribution Systems (PDS)
Modular switchgear and distribution control units for three-phase industrial power. Common faults include contact degradation, thermal relay misalignment, and auxiliary circuit failures in harsh Indian manufacturing environments.
DBT Automation Control Modules (ACM)
Programmable logic controllers and motor control centres for process automation. Typical issues include firmware corruption, relay contact wear, and capacitor aging in high-temperature foundries and cement plants.
DBT Soft Starters & VFDs (Variable Frequency Drives)
Electronic motor starters and variable speed drives for pump, fan, and compressor applications. Common failures: IGBT module damage, control circuit faults, and thermal sensor failures under Indian dusty operating conditions.
DBT Relay & Protection Systems
Electromechanical and solid-state protection relays for motor and feeder protection. Failure modes include coil burnout, contact arcing, and time-delay calibration drift in Indian industrial networks with unstable power supply.
DBT Capacitor Banks & Power Factor Correction
Reactive power control and harmonic filtering units for industrial power networks. Typical issues: capacitor element failure, thyristor switching faults, and microprocessor lockup from voltage transients in Indian grid conditions.
DBT Terminal Blocks & Connection Systems
Industrial-grade terminal blocks, busbars, and connectors for power and signal distribution in control cabinets. Common faults: corrosion of copper contacts, loose crimped terminals, and plastic insulator degradation from high ambient temperatures.

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 DBT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DBT equipment arriving at our workshop.
- ✓Power distribution unit contact burning and arcing — Copper contacts in DBT PDS switchgear suffer oxidation and micro-welding under high current transients and low power factor loads. Humid, dusty Indian factory environments accelerate contact corrosion.
- ✓Soft starter thyristor gate drive failure with phase imbalance — DBT soft starters experience thyristor firing circuit faults when exposed to voltage spikes from utility fluctuations or welding equipment interference common in Indian plants. Gate drive optoisolators degrade from thermal stress.
- ✓Electromechanical relay coil burnout and non-pickup — DBT protection relays exposed to sustained overvoltage, sustained underload conditions, or moisture ingress fail when coil insulation breaks down. Indian industrial sites with poor earthing practices increase this risk.
- ✓Capacitor bank element swelling and internal short-circuit — DBT PFC capacitor banks degrade under sustained harmonic distortion (THD > 5%) common in Indian industrial parks with multiple non-linear loads. Elevated ambient temperature in unventilated cabinets accelerates internal chemical breakdown.
- ✓Automation Control Module (ACM) display blackout and memory loss — DBT ACM controllers experience display and memory faults from power supply rail collapse due to filtering capacitor aging. Electrolytic capacitors in industrial-rated supplies have 5-7 year lifespan in 40°C+ ambient conditions typical of Indian manufacturing units.
- ✓Terminal block corrosion and loose wire crimp connections — DBT copper terminal blocks in high-humidity or salt-air Indian coastal industrial zones suffer green patina corrosion. Loose crimped terminals cause intermittent open circuits and equipment reset faults, especially at critical motor start sequences.

Frequently Asked Questions — DBT Repairs
Do you repair DBT equipment anywhere in India?+
Yes. Synchronics repairs the full DBT product range including power distribution switchgear, soft starters, VFDs, protection relays, and capacitor banks. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all major industrial hubs. Centralised 180+ engineer facility in Vadodara, Gujarat ensures consistent factory-level diagnostics.
How do you diagnose faults in DBT soft starters and VFDs?+
Synchronics uses curve tracer analysis to test individual thyristor and IGBT elements, applies automated frequency response testing to gate drive circuits, and performs comprehensive three-phase motor load simulation testing. We generate detailed fault reports identifying root cause — whether thyristor failure, gate driver malfunction, or control PCB fault — with photograph documentation and repair scope.
What is your turnaround time for DBT switchgear and PDS unit repairs?+
Standard turnaround is 3-5 working days for DBT power distribution systems and switchgear. Complex faults requiring custom part fabrication or international spares may extend to 7-10 days. Emergency same-day diagnostic and expedited repairs available for critical production equipment. Synchronics offers on-site diagnostic support and temporary equipment rental to minimise downtime.
Do you use genuine DBT spare parts or alternatives?+
Synchronics prioritises genuine DBT components for critical contact assemblies, coils, and power semiconductor elements. For commodity items — capacitors, resistors, diodes — we source industrial-grade equivalents from trusted Indian suppliers when DBT spares are unavailable or import-delayed. All parts carry 12-month warranty and are documented on your repair invoice.
Can you repair DBT equipment that has been damaged by lightning or voltage surge?+
Yes. Synchronics evaluates secondary damage from surge events using thermal imaging and electrical testing. We replace damaged semiconductor elements, power supply components, and control circuits. Where internal busbar or contact damage is severe, we source replacement DBT modules or coordinate refurbished units from our network. Lightning damage claims require detailed documentation for insurance.
How do I send my DBT 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 DBT 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 DBT 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 DBT 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.
