DART CONTROLS Product Lines We Repair
Our engineers are trained on the full DART CONTROLS product range. Below are the major product families we service.
DART Controls DC Drive Series (SCR-based)
Thyristor-controlled DC power supplies and drives for motors up to several horsepower. Common issues include SCR firing circuit failures, gate drive transformer burnout, and reference signal loss. Synchronics specializes in crowbar circuit repair and armature control restoration.
DART Controls AC Inverter/VFD Range
Variable frequency drives for three-phase AC motors with integrated PID loop control. Typical faults involve IGBT module failure, capacitor bank degradation, and communication board malfunction. Synchronics offers complete power stage refurbishment and control logic reprogramming.
DART Controls Servo Amplifier Systems
High-bandwidth servo drives for closed-loop motor control in precision positioning applications. Common repair needs include feedback amplifier circuit failure, PWM driver stage breakdown, and encoder interface board faults. Synchronics restores full servo loop performance.
DART Controls Process Control Modules
Analog signal conditioning and multi-function control cards for process automation and motor soft-starters. Issues include analog input/output channel failure, isolation transformer breakdown, and relay contact arcing. Synchronics rebuilds signal conditioning circuits completely.
DART Controls Field-Mount Controllers
Robust panel-mount and rail-mount drive controllers for mill, pump, and compressor applications. Repair focuses on terminal block corrosion, potentiometer drift, and internal fuse/contactor failure. Synchronics offers full enclosure refurbishment.

Common DART CONTROLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DART CONTROLS equipment arriving at our workshop.
- ✓DART Controls SCR firing circuit failure — Gate drive transformer saturation or winding insulation breakdown in legacy DC drives, often due to thermal cycling or moisture ingress in Indian industrial environments with high humidity.
- ✓DART Controls DC drive armature voltage regulation loss — Reference amplifier drift, tachometer feedback circuit failure, or analog signal comparator malfunction — common in plants with inconsistent mains voltage or poor grounding practices.
- ✓DART Controls AC inverter IGBT module catastrophic failure — Thermal cycling stress on solder joints, phase-to-phase fault propagation, or inadequate heatsink contact causing junction temperature runaway. Moisture-laden Indian monsoon environments accelerate solder joint fatigue.
- ✓DART Controls servo amplifier feedback loop instability — Encoder connector corrosion, differential amplifier offset drift, or compensation capacitor aging in the closed-loop control circuit — causing oscillation or loss of precision positioning.
- ✓DART Controls multi-function control card analog output channel dead — Output stage transistor failure, DAC integrated circuit malfunction, or PCB trace corrosion bridging in humid Indian plant floors. Terminal block rust accelerates circuit degradation.
- ✓DART Controls soft-starter contactor or SCR fails to trigger — Control signal path interruption, timing capacitor leakage, or phase detection circuit failure preventing synchronized SCR gate pulses. Poor mains earthing in Indian industrial facilities increases transient noise coupling.

Frequently Asked Questions — DART CONTROLS Repairs
Do you repair DART Controls equipment anywhere in India?+
Yes. Synchronics repairs the full DART Controls product range including DC drives, AC inverters, servo amplifiers, and multi-function control modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and all other major cities. All repairs are handled at our main facility in Vadodara, Gujarat, with turnaround typically 7-14 days depending on severity.
Can Synchronics repair my old DART Controls SCR DC drive or do I need replacement?+
Absolutely. DART Controls SCR-based DC drives are highly repairable — in fact, many Indian plants prefer restoration over replacement because the control topology is robust and proven. Synchronics routinely restores 20+ year-old DART Controls drives. Gate drive transformers, SCR modules, and control circuit components are either factory-original or industrial-grade equivalents. We provide 12-month warranty on all DART Controls drive repairs.
What is the typical cost and turnaround time for DART Controls AC inverter repair?+
DART Controls AC inverter repair cost depends on fault severity — typically Rs. 8,000 to Rs. 35,000 for IGBT replacement, capacitor bank refresh, or control board restoration. Turnaround is 7-10 days for standard repairs, 14+ days if custom programming or firmware recovery is needed. Synchronics provides free fault diagnostic report within 24 hours of receipt, so you know costs upfront before repair authorization.
Do you offer DART Controls drive firmware recovery or reprogramming?+
Yes. Synchronics has in-house expertise extracting and restoring DART Controls firmware from backup copies or by reverse-engineering control logic from engineering prints. We reprogram DART Controls servo amplifiers, process controllers, and drive modules to exact original specifications or to updated firmware if requested. Full parameter retention and loop tuning is provided as part of our comprehensive repair service.
How do I know if my DART Controls drive is worth repairing versus replacing?+
If your DART Controls drive is less than 25 years old, we almost always recommend repair — the cost is typically 30-50% of a new drive replacement, and availability of DART Controls legacy models is limited. Even for older units, if the main control chassis is intact and only power components or signal circuits have failed, restoration is economical. Contact Synchronics for a free technical assessment; we'll advise whether repair or replacement makes sense for your application.
How do I send my DART CONTROLS 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 DART CONTROLS 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 DART CONTROLS 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 DART CONTROLS 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.
