Mecer 850VA Line Interactive UPS (ME-850-VU)

The Mecer ME-850-VU is a compact and reliable 850VA line-interactive UPS designed to provide uninterrupted power and surge protection for desktop computers, routers, CCTV systems, and other sensitive electronics. Featuring Automatic Voltage Regulation (AVR), it stabilizes voltage fluctuations without draining the battery, extending battery life and ensuring continuous operation in environments with unstable power. With a backup time of 5–20 minutes depending on load, this UPS is ideal for homes, small offices, and light commercial setups.

Product Features

Line-Interactive Technology with AVR

Automatically regulates voltage fluctuations using AVR, protecting connected devices from under-voltage or over-voltage events without depleting the battery.

Reliable Backup Power

Provides 850VA/480W output, maintaining critical device operation during short power outages. Typical runtime ranges from 5 to 20 minutes depending on load.

Compact and Lightweight Design

Small form factor (287 x 100 x 142 mm) and lightweight (approximately 4.9–5.4 kg) allow easy placement in limited spaces.

Cold Start Function

Enables the UPS to start directly from the battery when mains power is unavailable, providing immediate backup during outages.

Microprocessor-Controlled Operation

Ensures precise power management, fast response to voltage disturbances, and high reliability for connected devices.

Auto-Restart and Off-Mode Charging

Automatically resumes operation when AC power is restored, and continues charging the battery even when the unit is off.

Comprehensive Protection Suite

Safeguards devices against overload, short circuit, deep discharge, and overcharge. Includes RJ-11/RJ-45 protection for phone, fax, or network lines, plus surge protection up to 175 Joules.

User Indicators and Alarms

• Visual: Green LED for AC mode, yellow flashing for battery mode, red for fault.
• Audible: Beeps for battery mode, low battery, overload, and continuous alarm for faults.

Optional Connectivity

Supports USB communication for monitoring via PC software like PowerMaster, allowing real-time status tracking and safe shutdown management.
