    The APC Back-UPS CS BK500EI is a 230V, 500VA/300W UPS for home-office or small-office equipment that needs battery backup during brief power interruptions. It provides three IEC C13 battery-backup outlets, additional surge-protection outlets, and USB/RS-232 connectivity; its capacity suits modest loads rather than high-power systems.

    Recommended For

    • Small-office PC users who need a short window to save work and shut down during an outage; the unit supports USB/serial monitoring and automatic shutdown software.
    • Small CCTV setups that need battery backup and surge protection for brief power interruptions, as long as the connected load stays within the UPS’s 300 W limit.
    • 230 V point-of-sale operators who want a checkout terminal to remain powered long enough to preserve work or shut down during a short outage.
    • Users of compatible 230 V projectors with brief startup power demand who want battery backup for short interruptions; the connected equipment must remain within the unit’s capacity.
