Product Features
Product Overview
The APC Back-UPS CS 350VA Tower UPS delivers reliable battery backup and surge protection for essential electronics in home office, small business, and point-of-sale environments. This standby UPS system provides 350VA of power capacity, ensuring connected devices remain operational during short power outages and brownouts. Engineered with a stepped approximated sine wave output, it offers stable power correction for voltage fluctuations.
The unit includes six NEMA outlets—three with battery backup and surge protection plus three with surge protection only—accommodating multiple devices. Its tower form factor and compact footprint make it suitable for placement under desks or in tight spaces. With a single-phase 120V input and 120V AC output, it matches standard North American power requirements, while the maintenance-free lead-acid battery provides practical runtime for graceful shutdowns.
Management features include a comprehensive LED status display with indicators for On Line, On Battery, Replace Battery, Site Wiring Fault, and Overload conditions. Audible alarms activate for on-battery, low-battery, and overload events. Connectivity options include USB and serial ports for software monitoring and control, and RJ-11 dataline protection extends surge coverage to telephone or fax lines.
Technical Overview
This UPS operates on a single-phase 120V input with a 10A input current, delivering 120V AC output through a stepped approximated sine wave. The 350VA load capacity supports essential equipment, with a surge energy rating of 1020 J for robust protection against spikes and lightning. The maintenance-free lead-acid battery provides a full-load runtime of 6.6 minutes and extends to 23.7 minutes at half load, giving users adequate time to save work and shut down equipment gracefully.
The typical battery recharge time is eight hours, ensuring the UPS is ready for subsequent power events. Environmental specifications include a maximum operating temperature of 113°F (45°C), sound emission of 45 dB(A), and thermal dissipation of 20 BTU/h. The unit features a beige finish, measures 6.50" (165 mm) high, 3.58" (91 mm) wide, and 11.18" (284 mm) deep, and weighs approximately 12.52 lb (5678.98 g).
