Online UPS Maintenance & Engineering
Preventative Audits, dynamic load profiling, and emergency SLAs designed to protect heavy factory floors.
Securing Critical Power with Certified Engineering
In high-output manufacturing sectors—such as savar's textile centers and gazipur's dynamic industrial belts—utility grid sags are not just an annoyance; they represent immediate operating loss. The **Maxon Online UPS Service** is specifically structured to eliminate electrical anomalies before they hit your factory floor.
Our team of certified power electronics engineers doesn't just run standard voltage probes. We perform comprehensive thermal imaging audits, execute high-power dynamic load tests, inspect circuit switch tolerances, and calibrate inverter controls. This comprehensive preventative maintenance methodology guarantees maximum system reliability and doubles the average lifetime of your battery strings.

Our 4-Phase System Calibration Protocol
We do not rely on guesswork. Every single UPS serviced by Maxon undergoes a formal, audited diagnostic procedure designed to uncover weak links before they interrupt operations.
Thermographic Analysis
Using high-resolution Fluke thermal imagers to scan critical internal systems. We locate high-resistance contact joints, loose busbar bolts, and thermal anomalies in the rectifier/inverter IGBT modules before they lead to catastrophic switch failure.
Dynamic Load Bank Profiling
Connecting our high-power resistive and inductive load banks to simulate actual facility stress states. We check the output voltage recovery envelope across transient load steps (0% to 100%), measuring dynamic response time and stability.
Battery String Balancing
Auditing individual battery cells within the high-voltage DC string. We measure internal cell impedance, check for thermal runaway, and calibrate temperature-compensated float charge outputs to prevent premature cell failure and thermal bloating.
Static Switch & Phase Sync Calibrations
Testing high-speed static bypass SCR gates to ensure seamless utility-to-inverter transitions. We verify the Phase-Locked Loop (PLL) synch circuitry to guarantee zero phase-angle difference, keeping transfer times at true 0ms.
Industrial Case Profiles
Understanding the precise impact of power disturbances across primary industry sectors.
Textile & Spinning Mills
Even a 50ms voltage sag causes high-speed ring frames and weaving looms to trip, resulting in massive thread breakage, hours of reset downtime, and wasted raw materials.
Custom-configured 3-phase Online UPS systems with active harmonic filters and robust industrial bypass paths to buffer sags.
Healthcare Infrastructure
Medical imaging tools like MRI magnets and CT scanners require pristine double-conversion power. Voltage ripples degrade diagnostic resolutions and threaten sensitive patient life-support modules.
Medical-grade double-insulated Online UPS setups with isolation transformers to completely isolate output neutrals.
Tier III Data Centers
Unplanned server downs damage storage block units and disrupt customer databases, causing immediate financial and brand damages.
N+1 redundant UPS topologies with dual input feeds and hot-swappable battery strings for zero-downtime maintenance.
Failure Signals
If your operations team registers any of these electrical warning triggers, contact our emergency Savar engineering desk immediately to schedule a priority preventative site audit.
High DC Bus Voltage Ripples
Deteriorating filtering capacitors in the DC rectifier link, leading to excessive battery wear and eventual inverter trips.
Immediate capacitive bank load analysis and replacement of electrolytic capacitor arrays.
Abnormal Transformer Humming
High levels of total harmonic distortion (THD) generated by non-linear facility loads saturating the magnetic cores.
Harmonic filtering injection audits and transformer core tightening.
Elevated Battery Impedance
Sulphation on the lead plates due to undercharging or high ambient operating temperatures.
Conductive string test, capacity equalization, or targeted block replacements.
