Tripp Lite's INTERNET350U standby UPS system offers complete protection from blackouts, brownouts and transient surges on both AC and dialup modem lines. Provides seamless battery support during brownouts and power failures with enough runtime to save and shutdown connected equipment without data loss. Offers complete power protection in an ultra-compact, flat-pack housing with an appearance closer to a power strip than other bulky UPS designs. Includes 3 battery supported outlets for computer, monitor and one vital system peripheral, plus 3 additional surge suppression-only outlets for printers and other system accessories not requiring battery support. USB port enables optional unattended system shutdown without data loss in the case of extended power failure.
