## Long description

The APC Back-UPS BK550EI is an uninterruptible power supply designed to protect office equipment and data from power surges, spikes and blackouts. It includes six power outlets—three with battery backup for uninterrupted operation during outages and three for surge-only protection. The unit provides data line protection via an RJ45/analog phone line suitable for phone, fax, modem or DSL connections. Physical dimensions are 16.5 x 9.1 x 28.4 cm and the unit weighs 6.32 kg. At a 100 W load, the UPS delivers approximately 24 minutes and 20 seconds of runtime.
Advantages
The BK550EI combines battery backup and surge protection in a compact form factor, allowing continued operation of essential devices during short power failures while protecting connected equipment from voltage transients. Integrated data line protection helps safeguard communication lines. The six outlets separate battery-backed and surge-only loads for flexible equipment arrangement.

How to use
Place the BK550EI on a stable, flat surface with adequate ventilation and connect essential equipment to the battery-backed outlets and noncritical devices to the surge-only outlets.

Follow the manufacturer's user manual for initial charging, battery testing and periodic maintenance to ensure reliable operation.
Recommendations
