KStar Offline UPS - 850VA

In an environment where power fluctuations and outages are common, KSTAR 850VA Offline UPS offers reliable backup protection to safeguard your sensitive electronics. Whether for a computer, router, surveillance system, or small home devices, this UPS ensures that sudden interruptions or voltage drops don’t lead to data loss or device damage.

This unit uses a standby (Offline) architecture: under normal conditions, devices are powered directly from the mains, and when mains power fails or drops below safe thresholds, it switches seamlessly to battery power. The transition time is minimal, ensuring that connected devices continue operating without noticeable disruption. It is designed to provide short-term power — enough to finish a task, save your work, or prepare for a safe shutdown.

According to the seller, the KSTAR 850VA has a nominal rating of 850 volt-amps (VA), corresponding to an estimated load capacity of ~360 watts. It includes an internal battery rated 12V / 9Ah (1 unit), allowing temporary operation during outages. The input and output frequency is 50 Hz ± 1 Hz, and the unit operates at a low noise level under 40 dB.

Safety is also built in: the UPS features protections against short circuits and overloads, helping prevent damage to your connected equipment. It offers a practical and cost-effective solution for home or office setups in need of basic energy protection against power interruptions.
