GNB TECHNOLOGIES Product Lines We Repair
Our engineers are trained on the full GNB TECHNOLOGIES product range. Below are the major product families we service.
Sprinter UPS Systems
Modular UPS platforms delivering 10kVA to 300kVA with sealed lead-acid and lithium-ion battery options. Common issues include battery charger faults, inverter module failures, static bypass contactor wear, and battery terminal corrosion affecting load transfer.
Absolyte Battery Systems
High-performance industrial battery banks for telecom, utility, and data centre applications. Frequent repair needs involve cell voltage imbalance, charger output drift, battery terminal oxidation, and BMS (Battery Management System) sensor failures.
PowerSafe Battery Technology
Lead-acid battery modules with advanced separator technology for float and cyclic duty. Repair focuses on cell plate damage, sulfation recovery, electrolyte level management, and equalization charger circuit restoration.
Rectifier Modules and Chargers
Three-phase and single-phase battery charging rectifiers for 48V, 110V, and 220V systems. Common faults include transformer overheating, bridge diode failures, output voltage regulation loss, and sensing circuit malfunctions.
Remote Monitoring Control Modules
Battery and UPS supervision electronics with SNMP, Modbus, and analog alarm outputs. Repair addresses firmware corruption, relay drive failures, sensor interface problems, and communication port degradation.

Common GNB TECHNOLOGIES Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GNB TECHNOLOGIES equipment arriving at our workshop.
- ✓Battery voltage imbalance across cells — GNB Absolyte and PowerSafe batteries experience cell voltage drift due to charger equalization circuit failure, worn equalizer resistors, or aging cells with internal resistance mismatch. Imbalance reduces available capacity and shortens battery life.
- ✓Sprinter UPS loses AC output on power transfer — Static bypass contactors in GNB Sprinter systems fail to engage during inverter-to-mains transition due to solenoid winding degradation, dirt-blocked contacts, or micro-processor control board timing failures. Load is momentarily disconnected, causing critical system shutdown.
- ✓Charger output voltage drift above 2.35V per cell — GNB rectifier modules and chargers develop voltage regulation loss when feedback sense resistor networks drift, op-amp circuits age, or transformer secondary tap points degrade. Over-voltage accelerates water loss and plate corrosion in connected batteries.
- ✓Battery terminal corrosion and high resistance connection — GNB PowerSafe and Absolyte battery terminals oxidize from acid vapour exposure, moisture ingress, or insufficient terminal post design in Indian humid industrial environments. Connection resistance increases, reducing available current and generating heat.
- ✓Remote monitoring module communication timeout errors — GNB NetMonitor and Sentinel module RS-232, RS-485, or Ethernet ports fail due to connector corrosion, isolation amplifier IC failures, or firmware hang states caused by invalid SNMP trap messages. Host system loses real-time alarm visibility.
- ✓Rectifier transformer over-temperature shutdown — GNB RectaCharge modules overheat when cooling fan fails, core laminations short due to moisture ingress, or primary/secondary winding insulation breaks down. Charger enters thermal protection mode, halting battery charge and backup capability.

Frequently Asked Questions — GNB TECHNOLOGIES Repairs
Do you repair GNB Technologies equipment anywhere in India?+
Yes. Synchronics repairs the full GNB Technologies product range - Sprinter UPS systems, Absolyte battery banks, PowerSafe modules, rectifier chargers, and remote monitoring control cards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Repairs are processed at our Vadodara, Gujarat facility with 24-48 hour turnaround for most common faults.
What causes GNB Sprinter UPS battery charger failure and how do you repair it?+
GNB Sprinter chargers fail due to transformer winding degradation, output rectifier diode shorts, and feedback regulation circuit aging. Synchronics conducts full transformer insulation testing, replaces failed diode bridges, validates all op-amp circuits, and recalibrates output voltage. We use genuine GNB transformer cores and semiconductor matched pairs to restore factory performance and warranty integrity.
How do you restore GNB PowerSafe battery capacity after sulfation?+
GNB PowerSafe lead-acid batteries suffer sulfation when chronically undercharged or stored discharged. Synchronics applies precision desulfation charging protocols, measures cell voltage recovery, and tests capacity under controlled load. We inspect plate integrity via resistance testing, clean battery interiors of corrosion byproducts, and restore electrolyte density. If cells show internal resistance above 5 mohm, we recommend replacement.
Can Synchronics repair GNB NetMonitor remote monitoring modules with Modbus or SNMP failures?+
Yes. Synchronics diagnoses NetMonitor communication faults by testing RS-485 isolation circuits, Ethernet transceiver chips, and protocol stack firmware. We replace failed optocouplers, transceiver ICs, and connectors, then reload verified firmware from backup sources. Modbus and SNMP trap functionality is validated against live battery systems before release.
What preventive maintenance does Synchronics recommend for GNB Technologies UPS and battery systems in Indian industrial environments?+
For Indian plants with high humidity and dust, Synchronics recommends quarterly terminal cleaning, bi-annual charger calibration verification, annual battery capacity testing under load, and six-monthly firmware updates for monitoring modules. We offer preventive maintenance contracts with scheduled inspections, parts replacement before failure, and data logging of voltage, temperature, and cycle counts to predict battery end-of-life.
How do I send my GNB TECHNOLOGIES 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 GNB TECHNOLOGIES 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 GNB TECHNOLOGIES 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 GNB TECHNOLOGIES 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.
