APC Smart-UPS X 4U Rack/Tower UPS and External Battery Pack

APC Smart-UPS X is a family of 4U rack/tower UPS systems and external battery packs designed to protect critical IT equipment. The line includes rack/tower convertible UPS units and SMX120BP external battery packs that extend runtime (systems support expandable runtime with SMX120BP packs). The UPS models feature line-interactive pure sine wave outputs, LCD status displays, multiple outlet configurations and short-depth 4U designs for improved cable management. Batteries are sealed lead-acid with hot-swappable or user-replaceable options and approximate recharge times as specified by individual models. Management and graceful shutdown are supported via PowerChute and optional Network Management Card (NMC); some models integrate with EcoStruxure IT and provide advanced monitoring capabilities. The family is intended for servers, storage, networking and other commercial applications where extended runtime and reliable power protection are required.
