Mecer 650VA Line Interactive UPS (ME-650-VU)

The Mecer ME-650-VU is a compact 650VA line-interactive UPS designed to provide reliable backup power and surge protection for desktop computers, routers, and sensitive electronics. With built-in Automatic Voltage Regulation (AVR), it stabilizes voltage fluctuations without draining the battery, extending the battery life and ensuring consistent performance. Ideal for homes and offices in regions with unstable power grids, such as Kenya, this UPS offers fast response to power disturbances, smart protection features, and extended runtime for critical devices.

Product Features

Line-Interactive Technology with AVR

Automatically regulates voltage fluctuations using Boost and Buck AVR to protect connected devices and minimize battery usage during minor power variations.

Reliable Backup Power

Delivers 650VA/360W of output, ensuring continuity for essential electronics during short outages with a typical backup time of 5–10 minutes.

Compact and Lightweight Design

Small footprint (287 x 100 x 142 mm) and lightweight (~4.25 kg) make it ideal for desktop use or confined spaces.

Cold Start Function

Allows the UPS to start directly from the battery when mains power is unavailable, ensuring operation during complete power outages.

Microprocessor Control

Ensures rapid response to power disturbances, stable performance, and high overall reliability.

Auto-Restart

Automatically resumes operation when AC power is restored, reducing the need for manual intervention.

Comprehensive Protection Suite

Protects against overload, overcharge, deep discharge, and includes RJ-11/RJ-45 surge protection for phone and network lines.

User Indicators and Alarms

LED indicators for AC Mode, Battery Mode, and Fault status, combined with audible alarms for battery, low battery, and overload conditions, provide real-time system alerts.

Optional Communication & Management

Supports optional USB and RS-232 connectivity for use with UPS monitoring software such as UPSilon2000 for automated safe shutdowns.
