Product Features

Line Interactive Technology with AVR

Automatically stabilizes voltage to prevent under-voltage and over-voltage conditions without draining the battery, protecting connected devices and extending battery life.

LCD Display for Real-Time Monitoring

Provides live information on input/output voltage, load level, battery status, and fault alerts, allowing users to monitor system health at a glance.

Cold Start Function

Enables the UPS to power connected devices directly from its battery during complete mains power outages, providing immediate backup when needed.

Intelligent Battery Management

Optimizes battery charging using float charging technology, prevents overcharging, and extends battery lifespan to ensure consistent reliability.

Universal Output Sockets

Equipped with four universal outlets (typically 2 UK and 2 IEC), providing battery backup and surge protection for multiple devices without additional adapters.

Monitoring & Control Software

Includes a USB communication port and bundled software for automated logging, system alerts, email/SMS notifications, and graceful shutdown of connected devices.
