APC Back-UPS CS BK350EI UPS, 350 VA / 210 W, 4 × IEC C13

The Back-UPS CS 350 is the smallest CS model, sized for a till point with one computer, a card terminal and a router. In a short cut the devices stay on; in a longer one the computer has time to shut down cleanly.

Payments are not cut off

Three outlets have battery backup and surge protection; the fourth is surge-only. APC gives a typical runtime of about 13 minutes for a computer and monitor.

Clean shutdown

Connect the UPS to the computer over USB and PowerChute software can shut it down before the battery runs out, so files are not corrupted mid-save.

Mind the socket type

The outlets are IEC C13, so devices connect with computer power cables (C14 to C13). The battery is user-replaceable.
