DRELO Product Lines We Repair
Our engineers are trained on the full DRELO product range. Below are the major product families we service.
DRELO Frequency Drives (AC Inverters)
Three-phase frequency converters for AC motor speed control in compressors, pumps, and conveyors. Common faults include IGBT module failures, capacitor dry-out in tropical conditions, and EMC filter breakdown under high harmonic loads typical of Indian textile and cement mills.
DRELO Soft Starters
Electronic soft-starting devices for reducing inrush current in large motors (30-1000 kW). Repair focus: thyristor module deterioration, triggering circuit failures, and cooling system blockages from industrial dust ingress common in Indian sugar factories and steel plants.
DRELO Control Modules and PLCs
Programmable logic controllers and digital I/O modules for process automation in paper mills, refineries, and pharmaceutical manufacturing. Typical failures: memory corruption, relay coil burnout, and input isolation optocoupler degradation in humid coastal Indian facilities.
DRELO Power Factor Correction Capacitors
Three-phase harmonic-suppressed capacitor banks for reactive power compensation in heavy industrial loads. High failure rates in Indian plants due to voltage fluctuations and heat stress; characterized by bulging, leakage, and internal short-circuit faults.
DRELO Motor Protection Relays
Digital thermal overload and phase-loss protection devices for motors in food processing, spinning mills, and chemical plants. Common issues: CT saturation, relay firmware bugs causing nuisance trips, and thermal probe calibration drift in high-ambient temperature environments.

Common DRELO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DRELO equipment arriving at our workshop.
- ✓IGBT Module Short-Circuit in DRELO Drives — Thermal cycling stress from India's 40-50°C ambient temperatures combined with inadequate cooling duct maintenance causes solder joint fatigue inside insulated-gate bipolar transistor modules. Sudden short-circuit triggers overcurrent shutdown and complete drive failure within hours.
- ✓Electrolytic Capacitor Dry-Out and Bulging — DRELO DC bus and filter capacitors degrade rapidly in Indian textile mills and foundries where ambient temperatures reach 55°C+ and voltage transients from supply fluctuations stress dielectric film. Capacitance drops below 80% rated value, causing bus voltage ripple and intermittent EEPROM corruption errors.
- ✓Thyristor Gate Drive Circuit Failure in Soft Starters — Moisture ingress combined with vibration-induced PCB cracking in sugar mill environments damages opto-isolator gates and gate-resistor networks. Thyristors remain permanently latched or refuse to fire, preventing smooth motor acceleration and triggering protective shutdowns.
- ✓Relay Contact Welding and Coil Burnout — DRELO control module relays experience contact arcing when switching inductive loads (solenoids, contactor coils) in steel rolling mills and cement plants. Arc erosion creates solder bridges; repeated inrush transients eventually burn out coil insulation, causing relay chattering or permanent open-circuit.
- ✓EMC Filter Capacitor Failure and Nuisance Tripping — Three-phase mains-side EMC filters in DRELO drives use Y-rated safety capacitors that degrade under harmonic distortion from neighbouring SCR drives and uncontrolled rectifiers in Indian foundries and electroplating plants. Capacitor leakage current exceeds earth-leakage relay sensitivity, causing repeated nuisance de-energisation.
- ✓Memory Corruption and Firmware Corruption in DRELO PLCs — Power supply ripple from neighbouring unregulated switching equipment in Indian pharmaceutical and food processing facilities exceeds DRELO PLC supply rail tolerance, corrupting EEPROM program storage. Plant stops without fault code, leaving operators unable to diagnose root cause.

Frequently Asked Questions — DRELO Repairs
Do you repair DRELO equipment anywhere in India?+
Yes. Synchronics repairs the full DRELO product range — frequency drives, soft starters, control modules, motor protection relays, and power factor correction capacitors. We offer PAN-India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other industrial cities. All repairs are performed at our 15000-sq-ft facility in Vadodara, Gujarat with same-day diagnostics and 5-7 day turnaround for most DRELO equipment.
How do I know if my DRELO drive has an IGBT fault versus a capacitor fault?+
IGBT shorts typically show as immediate current-limit shutdown (drive powers off within 1-2 seconds of start). Capacitor failures manifest as gradual reduction in output power, erratic speed control, or spontaneous restarts under load. Synchronics uses thermal imaging and in-circuit testing to differentiate: we photograph the drive under load, measure DC bus voltage ripple, and perform component-level testing. We can usually diagnose the fault within 2 hours of arrival at our workshop.
What is the typical cost of repairing a DRELO DFL-5000 frequency drive?+
DRELO DFL-5000 repair costs range from INR 15,000-45,000 depending on failure mode. IGBT replacement: 20,000-35,000. Capacitor replacement only: 8,000-15,000. Full PCB replacement with firmware reload: 40,000-45,000. Synchronics provides free diagnostic testing and written quotation before any repair work begins. Most customers find DRELO drive repair 40% cheaper than replacement, especially for 5-10 year old units still under productive use.
Do you stock DRELO spare parts or do I need to wait for imports?+
Synchronics stocks high-turnover DRELO components — IGBT modules, electrolytic capacitors, soft-start thyristors, relay modules, and control PCBs — in our Vadodara warehouse. For 90% of common DRELO failures, we source replacement parts within 24-48 hours from Indian distributors or German suppliers. Complex assemblies (drive firmware, custom control boards) may require 10-14 days for import, but we keep customers informed daily on parts status and provide loaner drives when production schedules are tight.
Can Synchronics repair DRELO equipment damaged by power surges or lightning strikes?+
Yes. Surge damage to DRELO drives typically destroys input rectifiers, mains-side varistors, and primary-side optocouplers while leaving secondary circuits intact. Synchronics replaces all surge-damaged components, tests the entire power stage under no-load conditions, and installs industrial-grade transient voltage suppression modules to prevent recurrence. For severe surge damage affecting multiple DRELO units, we recommend capacitive surge filters or ferroresonant transformers upstream of your drives to protect the full production line.
How do I send my DRELO 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 DRELO 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 DRELO 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 DRELO 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.
