Frequently Asked Questions

An Uninterruptible Power Supply (UPS) is an advanced power electronics system that provides immediate electrical energy to connected critical loads during utility power outages. In addition to battery backup, an online UPS continuously filters voltage fluctuations, electrical surges, sags, brownouts, frequency variations, and harmonic distortions, ensuring pristine power to sensitive electronics.

An active alarm can signify an impending battery failure, ambient over-temperature, output overload, or a cooling fan fault. First, note the exact numeric fault code or alarm message shown on the LCD panel. Do not abruptly power down the UPS unless smoke or electrical odors are detected. Ensure airflow around the unit is unobstructed and call our 24/7 technical hotline at +90 544 458 12 15 for remote guidance or emergency on-site dispatch.

Standard maintenance-free Sealed Lead-Acid (VRLA-AGM) batteries have a rated service life of 3 to 5 years when operated in a climate-controlled environment of 20°C–25°C. For every 10°C increase in ambient temperature, chemical degradation doubles, cutting battery lifespan in half. Regular conductance and impedance testing identifies weak blocks before catastrophic failure occurs. Contact GTK Elektrik for professional battery testing and environmentally certified replacements.

Preventive maintenance involves deep electronic diagnostics, thermal imaging of power semiconductors and busbars, electrolytic capacitor ESR inspection, air filter replacement, firmware updates, and controlled battery discharge load testing. Regular servicing prevents up to 90% of unexpected emergency downtime, preserves equipment warranty, and significantly extends the operational lifespan of high-capacity UPS assets.

Online Double-Conversion (VFI): Mains AC power is continuously rectified into DC to charge batteries and power the inverter, which generates a brand-new, pure sine wave AC output. Transfer time upon utility failure is exactly 0 milliseconds, offering absolute isolation from grid disturbances. Offline / Line-Interactive: The load is powered directly by utility grid power until a blackout occurs, incurring a 4 to 10 millisecond transfer delay. For data centers, medical devices, and manufacturing lines, Online Double-Conversion UPS is mandatory.

Sizing a UPS requires calculating the total active power (kW) and apparent power (kVA) of all connected loads, evaluating power factors, and accommodating high motor startup inrush currents (such as for elevators, compressors, and pumps). As a reliable engineering best practice, the nominal running load should not exceed 70%–80% of total UPS rated capacity to allow safe headroom and future expansion. GTK Elektrik offers complimentary on-site power auditing and load profiling.

GTK Elektrik provides vendor-agnostic maintenance, PCB component-level repairs, capacitor bank renewals, and battery replacements across all leading global and domestic manufacturers. Our certified engineers carry comprehensive diagnostic gear capable of servicing any UPS, static voltage stabilizer, or industrial rectifier installation.
