Product Features

850VA / 480W Power Capacity
Provides sufficient backup for essential low-power devices including PCs, routers, switches, and small office equipment, helping prevent data loss during outages.

Automatic Voltage Regulation (AVR)
Boosts or reduces voltage without switching to battery power, stabilizing output for connected equipment and extending battery life in unstable power environments.

Built-in Surge Protection
Safeguards sensitive electronics from harmful surges and spikes caused by lightning, grid fluctuations, or sudden voltage changes.

Simulated Sine Wave Output
Delivers a cost-effective, reliable power output compatible with most consumer electronics and office equipment.

Cold Start Function
Enables the UPS to power devices directly from the battery, even if there’s no utility power, ensuring immediate backup capability during outages.

Off-Mode Charging
Keeps the internal battery charged even when the UPS is powered off, so it’s always ready to provide backup power when needed.

USB Communication Port
Allows monitoring of UPS performance and battery status via optional software, providing real-time insights and control when connected to a PC.

RJ-11/RJ-45 Line Protection
Protects telephone, modem, or Ethernet lines from electrical surges to prevent data loss and equipment damage.
