KSTAR UA300 3000VA / 1800W Line-Interactive UPS with AVR

3000VA LCD LINE INTERACTIVE UPS, WITH INTERNAL BATT, 3-PIN BS PLUG (4XUniversal output socket, USB Cable, 2XNetwork Port, british cables)

Description

The KSTAR UA300 3000VA Line‑Interactive UPS is a high-capacity uninterruptible power supply designed to protect computers, networking equipment, and office electronics from power interruptions, voltage fluctuations, and electrical surges. With a 3000VA / 1800W power capacity, it provides reliable backup power to keep critical systems running during outages and prevents data loss or equipment damage.

This UPS uses line-interactive technology with Automatic Voltage Regulation (AVR) to stabilize incoming power. AVR automatically corrects low and high voltage conditions without switching to battery power, helping extend battery life and ensure a stable power supply to connected devices.

The UA300 features simulated sine wave output, fast transfer time, and multiple built-in batteries to deliver dependable backup power during blackouts. It also includes advanced protection such as overload and overcharge protection, self-diagnostic functions, and communication interfaces for power monitoring.

Designed for small offices, workstations, networking systems, and IT equipment, the KSTAR UA300 ensures continuous operation and protects valuable electronics from unexpected power disruptions. Its tower design and easy-to-monitor indicators make it suitable for both business and professional environments.
