Mecer 3KVA Line Interactive UPS (ME-3000-VU)

The Mecer 3KVA Line Interactive UPS (ME-3000-VU) is a high-capacity uninterruptible power supply designed to provide reliable backup power and voltage regulation for critical electronics. With a capacity of 3000VA / 1800W, it supports servers, workstations, networking equipment, and high-end home systems during power outages and voltage fluctuations. Its advanced Line-Interactive topology with Automatic Voltage Regulation (AVR), robust battery backup, and intelligent monitoring ensures continuous operation and protection for sensitive devices in offices, data centers, and home environments.

Product Features

Automatic Voltage Regulation (AVR)

Stabilizes input voltage by boosting low voltages and reducing high voltages without using battery power, extending battery life and ensuring stable operation for connected equipment.

Power Protection

Built-in safeguards protect against surges, overloads, deep discharges, and overcharging, keeping devices safe during electrical disturbances.

Cold Start Function

Allows the UPS to start using its internal batteries even when mains power is unavailable, providing emergency backup when needed.

Smart Monitoring and Communication

Equipped with USB and RS-232 ports, the unit supports power management software on Windows, Linux, Unix, and macOS. LED or LCD displays provide real-time status of battery level and load, along with audible alarms for faults or low battery conditions.

Data Line Protection

Integrated RJ-11/RJ-45 ports protect telephone, modem, and network lines from electrical spikes, preventing damage to connected systems.

Microprocessor-Controlled Management

Advanced microprocessor control ensures precise voltage regulation, reliable performance, and efficient battery utilization compared to standard analog UPS units.
