APC Back-UPS 650VA Tower 230V 4-Outlets UPS

The APC BK650EI is a tower style Back-UPS that keeps your essential electronics running and protected when the mains supply fails. With a capacity of 650 volt-amperes or 400 watts, it covers the power needs of a desktop computer, a Wi-Fi router, and other small office or home office devices long enough for you to save work, maintain an internet connection, or shut down equipment safely.

The unit accepts 230 volt input and offers four IEC C13 outlets. Three outlets provide both battery backup and surge protection, while the remaining outlet guards against surges only. This layout lets you reserve battery runtime for the devices that matter most while still shielding less-critical gear from voltage spikes.

USB and serial communication ports connect the UPS to a computer or server so you can monitor power status, schedule safe system shutdowns, and receive alerts through APC software or standard operating-system tools. Built-in intelligent battery management and an automatic self-test routine help you track battery health and maximize service life without guesswork.

When the sealed lead acid battery approaches the end of its lifespan, you can replace it yourself without sending the unit for service. After a complete discharge, the battery reaches full charge in about eight hours, ready for the next outage. Audible alarms and front-panel LED indicators provide instant feedback on load level, battery condition, and power events, while third-party safety certifications add confidence in demanding environments.

Whether you are a remote worker who needs to stay online, a small business owner protecting point-of-sale systems, or a gamer who cannot afford abrupt shutdowns, the tower design fits neatly beside a desk or under a counter and delivers dependable, straightforward protection for valuable equipment and data.
