BEST POWER Product Lines We Repair
Our engineers are trained on the full BEST POWER product range. Below are the major product families we service.
Ferrups Industrial UPS
High-availability three-phase UPS delivering 10 kVA to 80 kVA for industrial plants. Common faults include rectifier bridge failures, IGBT module degradation, capacitor aging, and battery charger inefficiency under heavy load cycles.
Patriot Pro UPS
Compact single/three-phase UPS (2-20 kVA) for process automation, CNC machines, and assembly lines. Typical issues: input surge suppression failure, output isolation transformer winding faults, and LCD display controller burnout.
Npower Series UPS
Enterprise-grade modular UPS for data centers and telecom switching centers (15-150 kVA). Prone to parallel redundancy module sync errors, DSP control board firmware crashes, and static switch commutation faults under dynamic loads.
BEST Battery Management System (BMS)
Intelligent battery monitoring and equalization modules for extended runtime configurations. Repairs involve cell voltage sensor failures, balancing relay faults, and communication link errors between BMS and main UPS controller.
Static Bypass Modules
Critical switching components ensuring mains supply takeover during UPS maintenance or overload. Failures include contactor coil burnout, zero-crossing detection circuit faults, and thyristor firing circuit malfunction.

Common BEST POWER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BEST POWER equipment arriving at our workshop.
- ✓Rectifier Bridge Diode Failure - No Charging — BEST Power Ferrups and Patriot Pro rectifiers use six-pulse bridges rated for continuous industrial input transients. Diode junction degradation occurs under high-frequency switching loads or when mains voltage contains harmonic distortion common in Indian plants with VFD and welder populations.
- ✓IGBT Inverter Module Thermal Runaway — BEST Power Npower and high-capacity Ferrups inverters employ parallel IGBT stacks for redundancy. Thermal paste degradation, heatsink fouling from humidity and dust, and failed temperature-sensing thermistors cause localized hot-spots exceeding 150°C junction temperature, triggering cascade shutdown.
- ✓Bypass Switch Contactor Chattering — BEST Power static bypass circuits use AC contactors rated for zero-crossing detection and synchronized switching. In Indian facilities with unbalanced three-phase supplies and frequent load transients, coil mechanical wear causes intermittent contact closure, creating arcing and soot buildup on contacts.
- ✓Battery Charger Standby Voltage Drift — BEST Power charger modules maintain float voltage for lead-acid and lithium battery packs via precision feedback loops. Aged electrolytic capacitors in the feedback divider or failed op-amp comparators cause voltage creep above 2.4V/cell nominal, causing battery gassing and premature cell failure.
- ✓DSP Control Board Firmware Crash - Black Screen — BEST Power Npower and Patriot Pro controllers run embedded DSP firmware to manage rectifier/inverter PWM, battery current limiting, and mains synchronization. Power-supply brownout, firmware corruption during OTA updates, or memory address space collision causes watchdog timeout and CPU reset loops.
- ✓LCD Display Controller and Keypad Unresponsive — BEST Power front-panel HMI controllers use I2C or serial RS-485 communication to main UPS board. Moisture ingress into connector pins, failed opto-isolator modules, or shorted LCD segment driver IC cause signal loss and display blanking on Ferrups and Patriot Pro units.

Frequently Asked Questions — BEST POWER Repairs
Do you repair BEST Power UPS equipment anywhere in India?+
Yes, absolutely. Synchronics Electronics repairs the complete BEST Power portfolio—Ferrups, Patriot Pro, Npower, and all accessory modules—with nationwide pickup and delivery. We maintain service depots in Mumbai, Delhi, Bangalore, Hyderabad, Pune, Chennai, and our primary facility in Vadodara, Gujarat. Same-day triage and 48-72 hour turnaround on most faults. Call our hotline or submit your serial number online for instant evaluation.
What is the typical repair cost for a BEST Power Ferrups or Npower UPS?+
BEST Power repair costs depend on fault severity. Rectifier/IGBT module replacement typically runs INR 25,000-60,000. Battery charger repairs: INR 15,000-35,000. Control board replacement: INR 30,000-70,000. We provide transparent quotation after board-level diagnosis—no hidden labor charges. Extended warranty and preventive maintenance contracts are available for high-availability industrial sites.
Can you repair BEST Power UPS batteries and BMS modules separately?+
Yes. Synchronics offers standalone BEST Power battery string and BMS servicing. We test individual lead-acid/lithium cells using digital capacity analyzers, equalize battery stacks, and recalibrate charge voltage limits. BMS boards are repaired in-house with thermistor, relay, and optocoupler replacement. We maintain compatibility with Ferrups and Patriot Pro battery configurations—no need to buy OEM batteries at premium cost.
How do I prevent common BEST Power UPS faults in my Indian manufacturing plant?+
Synchronics recommends: (1) Annual preventive maintenance—filter replacement, thermal paste renewal, capacitor health checks. (2) Mains conditioning via isolation transformers if plant has heavy VFD/welder load. (3) Quarterly battery equalizer testing to detect cell aging. (4) Environmental control—maintain 15-25°C ambient and <70% RH to extend IGBT and capacitor life. We offer on-site PM packages tailored to your load profile and Indian climate conditions.
What is the warranty on BEST Power repairs from Synchronics?+
All BEST Power repairs carry a 12-month parts and labor warranty covering the same fault. Replaced modules are tested under full load for minimum 24 hours before warranty validation. Extended 24-month and 36-month warranties are available for critical infrastructure customers. We maintain spare rectifier, IGBT, and control board inventory for rapid replacement—no long delays waiting for factory shipment from USA.
How do I send my BEST POWER 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 BEST POWER 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 BEST POWER 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.
