The SUINT1500LCD2U SmartOnline® 208/230V 1.5kVA 1.35kW On-Line Double-Conversion UPS provides battery backup and AC power protection against blackouts, brownouts, power surges and line noise that can damage electronics or destroy data. It continuously regulates AC output within 2% of the selected nominal output voltage with zero transfer time from online to battery mode. Featuring six C13 outlets (four switchable) and a C14 input, the SUINT1500LCD2U has an internal battery that provides 12.6 minutes of support at half load and 4.5 minutes at full load. Adding external battery packs, such as BP36V27-2US (sold separately), provides extended runtime. Managing the SUINT1500LCD2U is simplified through the interactive front-panel LCD interface, which displays operating conditions and diagnostic data, such as load and battery levels. You can set power strategies to reflect your protection priorities, whether it’s precise power quality for sensitive systems or the highest possible electrical efficiency. EMI/RFI noise filtering improves your equipment’s performance and prevents damage. A 936-joule surge suppression rating protects your equipment from harmful power surges. With Tripp Lite’s free downloadable POWERALERT software, the SUINT1500LCD2U enables safe unattended system shutdown and file saves in case of a prolonged power failure.
