Model UKT-6K supports 6000VA / 5400W with True Online Double Conversion topology. It delivers continuous pure sine output and protects against sags, overvoltage, surges, and line noise. Ideal for servers, networks, production-line equipment, and POS systems requiring high stability.
How it works
Online Double Conversion
AC input is rectified to DC (Rectifier) to remove noise.
Inverter continuously supplies pure sine AC to the load.
When power fails, batteries take over with zero transfer time (0 ms).
Charging circuit manages batteries to extend service life.

FAQ – Frequently Asked Questions
Which UPS suits you best?
What devices can a UPS support? Click to view answer
Works with common IT/electronic devices: PCs/laptops, POS, NAS, routers/switches, NVR/DVR CCTV (via PoE), servers/workstations, telecom gear, and network devices. Avoid: Motor/compressor loads (water pumps, fridges, AC) or high-power heaters. Sizing tip: Sum device wattage and add at least 20–40%, and avoid running the UPS above ~80% of capacity.
Which type should I choose if outages are frequent? Click to view answer
Home/office:Line-Interactive + AVR, VA rating 1.5–2× total load. Choose Long Backup models or external batteries for longer runtime.
Critical/server workloads:Online (Double Conversion) for the most stable power, external battery options, SNMP/remote alerts.

How long do UPS batteries last? Click to view answer
Typically, Sealed Lead-Acid (SLA) batteries last around 2–3 years (at 20–25°C, normal use). Higher temperatures/frequent outages shorten life. Some brands offer Lithium packs with a rated life of 5–8 years. Care tips: Ensure ventilation, avoid deep discharges frequently, and test batteries every 6–12 months.
Can I replace the batteries? Click to view answer
Yes — many models support battery replacement (some are hot-swappable). Use genuine/same-spec batteries, power down and unplug before replacement, or have a technician perform it. After replacement, run self-tests/calibration via software and recycle old batteries properly.
