500 VA UPS with 4 C13 outlets and USB - APC Back-UPS CS BK500EI

The APC Back-UPS CS BK500EI is a 500 VA standby UPS with surge protection. Its 4 C13 outlets accommodate multiple devices, and a USB port provides a connection to your computer. The unit has a tower design with a beige finish and includes protection against overloads.

The VRLA lead-acid battery provides a minimum runtime of 3.8 minutes at full load and 13.8 minutes at half load, so the time available depends on the connected load. Automatic battery testing checks the battery, while audible alerts indicate a low battery or an overload. Surge protection also covers DSL, fax, modem and telephone lines.
