Common KEHUA TECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KEHUA TECH equipment arriving at our workshop.
- ✓IGBT rectifier module thermal runaway and burnout — KEHUA TECH IGBT modules in modular UPS units fail due to thermal stress from dust accumulation in Indian factory environments, inadequate heatsink cooling, or junction temperature exceeding design limits (typically >85°C). Vibration in manufacturing plants accelerates solder joint fatigue.
- ✓UPS battery charger overvoltage or regulation fault — KEHUA TECH battery charger circuits (especially in BMS-40/60 units) experience regulation drift due to feedback circuit capacitor aging, reference voltage IC degradation, or incorrect DC bus voltage. Common in facilities with unstable grid supply or poor UPS grounding.
- ✓Static switch or bypass contactor sticking or arcing — KEHUA TECH UPS10000 and UPS3000 static switch or electromechanical bypass contacts suffer from arcing debris, copper erosion, and contact welding caused by repeated load transients in Indian industrial plants or poor suppression of inductive switching spikes.
- ✓DSP control board communication or synchronization failure — KEHUA TECH UPS9000 and UPS3000 DSP boards experience corrupted firmware, I2C bus errors, or lost phase-lock synchronization with utility mains due to EMI ingress from adjacent welding or motor drive equipment common in Indian manufacturing zones.
- ✓Battery temperature sensor open or short circuit — KEHUA TECH temperature sensors embedded in battery strings or BMS modules develop intermittent connection due to corrosion, mechanical vibration, or insulation failure in humid Indian climates. Causes false over-temperature alarms or uncontrolled charging current.
- ✓Parallel UPS synchronization loss and circulating current — Multiple KEHUA TECH UPS modules (especially UPS3000-M series) configured in parallel lose phase synchronization due to firmware version mismatch, CAN bus termination issues, or hardware clock drift. Causes excessive circulating current and uneven load sharing.

Frequently Asked Questions — KEHUA TECH Repairs
Do you repair KEHUA TECH equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete KEHUA TECH UPS and power module range — modular UPS units, rectifier modules, inverters, and battery management systems. We offer PAN India door pickup and return delivery from Vadodara (Headquarters), with service centers and partnerships in Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, and other major industrial cities. Same facility ensures consistent quality across all repairs.
How do you diagnose faults in KEHUA TECH modular UPS systems like UPS3000-M?+
Synchronics uses KEHUA TECH proprietary diagnostic tools and OEM software to read real-time module status, voltage balancing, and error logs from the control DSP. We perform IGBT thermal imaging, battery charger output characterization, and static switch timing verification. We also apply AC line simulation to test synchronization and load-sharing logic before return. Our 180+ engineers understand KEHUA TECH's modular architecture deeply.
What is the typical turnaround time for KEHUA TECH UPS repair at Synchronics?+
Routine faults (battery charger, fan, sensor replacement) are repaired in 3-5 working days. Complex IGBT module replacement or DSP firmware rebuild takes 7-10 days. We offer express 24-48 hour repair for critical power modules if parts are in stock. We maintain stock of common KEHUA TECH components (IGBT modules, capacitors, relays) to minimize customer downtime in Indian manufacturing sectors.
Do you offer warranty on KEHUA TECH repairs?+
Yes. All Synchronics repairs on KEHUA TECH equipment come with 12 months extended warranty on replaced components and 6 months on repaired assemblies. We provide written test reports showing before/after performance parameters (input voltage regulation, output stability, load capacity). Warranty includes parts and labor for the same fault within the warranty period.
Can Synchronics repair KEHUA TECH UPS units with firmware issues or locked control boards?+
Yes, Synchronics is equipped with KEHUA TECH firmware programming tools and OEM release images. We can reflash corrupted firmware, unlock secured control boards, reset configuration to factory defaults, and reprogram site-specific parameters (battery voltage, load mode, alarm thresholds). This is common for used KEHUA TECH equipment purchased from secondary markets in India where configuration is lost or firmware is damaged.
How do I send my KEHUA TECH 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 KEHUA TECH 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 KEHUA TECH 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 KEHUA TECH 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.
