APC Smart-UPS SC 420VA 230V

The APC SC420I is an uninterruptible power supply that gives small offices, retail counters, and home labs a reliable safety net when the power flickers or fails. It delivers 420 volt amps or 260 watts of pure sine wave power, so sensitive electronics keep running smoothly instead of crashing or restarting during brownouts and outages.

Three outlets receive full battery backup while a fourth offers surge protection for hardware that only needs filtering. A built-in protector for Ethernet or DSL lines keeps network equipment safe from voltage spikes that can travel through data cables. At full load the unit provides up to five minutes of runtime, long enough to finish a transaction, save your work, or bring systems down in an orderly way.

The sealed lead-acid battery is hot-swappable, which means you can replace it without powering down connected gear. Front-panel LEDs show clear status and alert information at a glance. Setup is straightforward: an IEC C14 input, two included jumper cables, monitoring software, an RS-232 cable, and a user guide are all in the box.

With its compact tower format and weight of about nine kilograms, the SC420I fits easily on or under a desk, in a network closet, or next to a cash register. It is a practical choice for anyone who needs affordable power protection backed by a two-year repair or replace warranty.
