The APC Back-UPS Pro 900VA 230V Line Interactive UPS delivers the ultimate in battery backup and surge protection. The Back-UPS Pro family provides business-class power protection for office, network and electronic equipment. The Automatic Voltage Regulation (AVR) protects against mains failures, brownouts and surges.

The robust UPS battery backup provides continuous power for over three minutes at 500 Watts. This protects sensitive equipment and data and allows for the graceful shutdown of six connected devices. Surge protection is available for all devices.

In addition, the APC Back-UPS has USB and RJ45 connections. This protects mobile devices, networks and phone lines from voltage disruptions. In addition, PowerChute software allows for remote connectivity and power management. To ensure that devices have constant protection, the LCD status display provides key metrics at a glance. Also, automatic battery self-test ensures early detection of faults or maintenance issues. As an additional safety feature, audible alarms notify critical UPS power conditions. The manufacturer offers a two-year warranty.
