RENU ELECTRONICS Equipment We Repair — By Category
RENU ELECTRONICS Product Lines We Repair
Our engineers are trained on the full RENU ELECTRONICS product range. Below are the major product families we service.
RENU Power Supply Modules
Switched-mode and linear power supplies ranging 12V to 48V DC for control system applications. Common issues include capacitor degradation, rectifier failures, and thermal fuse nuisance trips in dusty mill environments.
RENU Industrial Relay Modules
Electromechanical and solid-state relay cards for motor control and load switching in automation circuits. Frequent failures include coil burnouts, contact arcing, and PCB trace corrosion from moisture ingress.
RENU Logic Control Boards
PLC-style digital input-output modules and sequential control boards for textile and packaging machinery. Typical repair needs involve input optocoupler failures, output relay contact welding, and firmware corruption.
RENU Temperature Control Units
PID-based thermostat controllers for industrial ovens, extruders, and heating chambers. Common faults include RTD sensor interface failures, solid-state relay burnout, and display LCD degradation.
RENU Analog Signal Conditioning
4-20mA isolators, amplifiers, and converter boards for process instrumentation loops. Typical defects include isolation transformer saturation, op-amp rail failures, and DIN-rail connector oxidation.
RENU Motor Control Contactors
AC and DC motor starter units with integrated protection logic and soft-start capability. Common repair scenarios involve coil short-circuits, mechanical jamming, and arcing damage to silver contacts.

Common RENU ELECTRONICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RENU ELECTRONICS equipment arriving at our workshop.
- ✓RENU power supply capacitor bulging and leakage — Electrolytic capacitors in RENU PSU modules age rapidly in tropical Indian mill environments with ambient temperatures 45-50°C and high dust contamination. Ripple current stress accelerates dielectric breakdown, causing electrolyte venting and PCB corrosion.
- ✓RENU relay module contact welding under inductive loads — RENU relay cards in Indian textile mills frequently switch large inductive loads (solenoids, electromagnets) without adequate snubber protection. Switching transients cause contact micro-welding, preventing relay release and causing machine lockups.
- ✓RENU logic board input optocoupler failures — High-voltage transients on input signal lines to RENU PLC boards cause optocoupler LED degradation and phototransistor junction breakdown. Common in food processing plants where AC motor soft-starters generate EMI spikes on sensor wiring.
- ✓RENU temperature controller RTD sensor open circuit — RENU thermostat RTD interface boards fail when Pt100 sensor leads corrode or break inside conduit routing through high-vibration zones in extruders or dryers. Intermittent connection causes false temperature readings and control instability.
- ✓RENU motor contactor coil short-to-frame and ground faults — Moisture ingress into RENU magnetic contactor coils causes insulation breakdown between the primary winding and frame. Moisture is particularly prevalent in coastal Indian plants and facilities with poor climate control, leading to high inrush currents and tripping.
- ✓RENU analog signal conditioning board isolation transformer saturation — RENU isolator boards in pharmaceutical plants experience prolonged DC offset on input signal lines due to sensor malfunction or transmitter faults. Sustained offset magnetizes the isolation transformer core, reducing secondary signal fidelity and causing measurement errors.

Frequently Asked Questions — RENU ELECTRONICS Repairs
Do you repair RENU Electronics equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete RENU Electronics product range including power supplies, relay modules, logic boards, temperature controllers, signal conditioners, and motor contactors. We offer PAN-India door pickup service from all major cities - Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and smaller industrial towns. All repairs are performed at our Vadodara, Gujarat facility with centralized test infrastructure. Typical turnaround is 3-7 business days.
What is the warranty on RENU Electronics repairs?+
Synchronics provides 12-month comprehensive warranty on all RENU Electronics repairs covering parts and labor. This warranty covers component failure due to manufacturing defects or aging. We also offer extended 24-month warranties for mission-critical equipment with additional validation testing. All repaired equipment undergoes 48-hour burn-in testing before dispatch.
Can you repair RENU power supply modules that have water damage or salt spray corrosion?+
Yes, we specialize in restoring water-damaged and salt-corroded RENU power supplies common in coastal Indian plants and facilities near rivers. We employ ultrasonic cleaning of PCBs, replace all electrolytic and film capacitors, apply conformal coating for moisture protection, and re-test all output voltages and load regulation. Restored units typically achieve 95%+ of original performance specifications.
Do you stock genuine RENU Electronics spare parts?+
Synchronics maintains authorized distributor inventory for RENU Electronics contactors, relay cards, and power supply modules. For custom PCB repairs, we source original components through RENU Electronics distribution channels in Bangalore and maintain common passive components (capacitors, resistors, diodes, transistors) for same-day availability. Lead times for specialized modules are typically 2-3 weeks if stocked items are unavailable.
How do I know if my RENU Electronics equipment needs professional repair versus simple troubleshooting?+
RENU equipment showing symptoms like intermittent output failures, thermal shutdown, unexplained fault codes, or physical damage (bulging capacitors, burn marks, corrosion) requires professional repair. Synchronics offers free telephone diagnostics - simply describe the symptoms and equipment model, and our engineers will advise if repair is needed or if firmware updates and parameter reset can resolve the issue. Email high-resolution photos of the PCB for detailed analysis.
How do I send my RENU ELECTRONICS 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 RENU ELECTRONICS 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 RENU ELECTRONICS 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 RENU ELECTRONICS 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.
