Lightwave LW 850VA 3 PIN UPS (LW-UPS-850)

The Lightwave LW-UPS-850 850VA 3 Pin UPS is a reliable line-interactive power backup solution designed for home and small office environments. Built to protect essential devices such as desktop computers, routers, and CCTV systems, it delivers stable power through automatic voltage regulation and fast transfer times. Its compact design, wide input voltage range, and intelligent protection features make it ideal for areas with frequent power fluctuations, ensuring uninterrupted performance and extended equipment lifespan.

Product Features

Automatic Voltage Regulation (AVR)

The built-in AVR system uses boost and buck technology to stabilize fluctuating input voltage between 140V and 300V without switching to battery power, helping preserve battery life and maintain consistent output.

Fast Transfer Time

With a transfer time of 2 to 6 milliseconds, the UPS ensures a seamless switch to battery mode during outages, preventing interruptions to connected devices.

Reliable Battery Backup

Equipped with an internal sealed lead-acid battery, the unit provides 10 to 20 minutes of backup for a typical desktop setup and extended runtime for lighter devices such as routers.

Simulated Sine Wave Output

Delivers a stable simulated sine wave output suitable for most home and office electronics, ensuring efficient and safe operation.

Advanced Protection Suite

Includes surge protection, overload protection, short-circuit protection, and battery overcharge prevention to safeguard both the UPS and connected equipment.

Cold Start Capability

Allows the UPS to power on and supply electricity to connected devices even when there is no mains power available.

Intelligent Monitoring System

Provides early warning alerts for battery health and performance, helping users take preventive action before issues arise.

Compact and Quiet Design

Designed for minimal space usage with low acoustic noise levels, making it suitable for both office and home environments.
