DINEMA Product Lines We Repair
Our engineers are trained on the full DINEMA product range. Below are the major product families we service.
DINEMA Braking Resistors
Wire-wound and metal film resistor modules designed for VFD overvoltage suppression and dynamic braking in AC drives. Common repairs involve thermal degradation, connection loosening, and resistive element failure under cyclic load.
DINEMA Load Banks
Electronic load simulation systems for UPS testing, generator commissioning, and drive load verification. Repair issues include contactor stiction, power module burnout, cooling fan failure, and sensor signal loss.
DINEMA Regenerative Systems
Energy recovery modules that convert motor braking energy back to supply. Common faults include rectifier bridge failure, DC bus capacitor aging, power stage short circuits, and firmware control errors.
DINEMA Cooling Modules
Liquid and air-cooled dissipation units for high-power resistor assemblies. Typical failures: cooling pump blockage, thermal sensor malfunction, fan bearing wear, and coolant leakage.
DINEMA Control Interfaces
Analog and digital control boards for resistor switching, load bank management, and regenerative system regulation. Repair needs: relay failure, analog input circuit faults, CAN bus communication loss, and firmware corruption.

Common DINEMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DINEMA equipment arriving at our workshop.
- ✓DINEMA resistor element open-circuit failure — Chronic thermal cycling in DBR and LB modules causes wire-wound elements to fracture at solder joints or develop micro-cracks under vibration. Inadequate cooling or exceeding rated duty cycle accelerates this degradation.
- ✓DINEMA load bank contactor chattering — Voltage fluctuations, coil spring fatigue, or contaminated contact surfaces in power contactors cause intermittent dropout or chattering during load switching. DINEMA LB-Series contactors are sensitive to supply transients.
- ✓DINEMA regenerative system DC bus capacitor overvoltage — Failed input charging circuit or shorted energy recovery switch in REC-series units allows bus voltage to rise uncontrolled during motor braking. Faulty voltage regulation firmware can prevent proper load shedding.
- ✓DINEMA cooling system pump failure — Scale buildup in liquid-cooled CM modules, cavitation from air entrainment, or bearing seizure in air-cooled fans reduces thermal dissipation. DINEMA systems operate at high duty in mills and steel plants where ambient contamination is severe.
- ✓DINEMA control board CAN bus communication loss — Corroded connectors, loose CAN termination resistors, or damaged transceiver chips on CI-Fieldbus boards prevent drive handshake. Inadequate shielding in noisy factory environments causes intermittent dropout.
- ✓DINEMA power module gate drive signal failure — Isolated DC supply failure, damaged optocoupler circuits, or broken ribbon cable connections between control board and IGBT gate drivers prevent device switching. Critical in REC and load bank power stages.

Frequently Asked Questions — DINEMA Repairs
Do you repair DINEMA equipment throughout India?+
Yes. Synchronics offers pan-India repair and recovery service for DINEMA braking resistors, load banks, regenerative systems, and control modules. We arrange door-to-door pickup from any Indian city — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and beyond. Equipment arrives at our 25000 sq. ft. repair facility in Vadodara, Gujarat, where our 180+ engineers perform diagnostics and repairs to factory standards.
What is the typical repair turnaround for DINEMA DBR braking resistor modules?+
Most DINEMA resistor modules are diagnosed and repaired within 3-5 working days. Routine element replacement or contact cleaning is quicker. Complex faults requiring custom resistor card programming or thermal analysis may extend to 7-10 days. We provide daily updates and expedite options available.
Can Synchronics test a DINEMA regenerative system before shipping it back?+
Absolutely. We perform full-load testing of REC-series regenerative systems, including bus voltage regulation under transient braking events, capacitor charge-discharge cycling, and power stage efficiency validation. Load banks simulate your actual motor brake duty. Test reports are provided documenting performance at 100%, 75%, and 50% rated load.
Are replacement parts for DINEMA equipment available through Synchronics?+
Yes. Synchronics sources genuine DINEMA spare parts — resistor elements, capacitors, contactors, cooling pumps, and control boards — directly from authorized distributors and DINEMA partners in Germany and India. We maintain inventory of high-demand items and can expedite orders for emergency restocking. All parts come with documentation and warranty.
Do you offer preventive maintenance or thermal imaging for DINEMA installations in Indian mills?+
Yes. Synchronics provides on-site preventive maintenance, thermal imaging of resistor modules and power dissipation systems, and electrical testing for DINEMA equipment installed in your facility. Our engineers can identify early signs of thermal stress, cooling degradation, or resistor aging. Scheduled maintenance reduces unexpected downtime in high-duty industrial environments like steel plants and textile mills.
How do I send my DINEMA 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 DINEMA 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 DINEMA 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 DINEMA 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.
