Best Power (Necedah, WI) recently introduced the Axxium Rackmount UPS line, which offers ratings from 1000VA to 3kVA. The new Axxium units are claimed to combine several features not previously found in a single UPS, including extended runtime, a compact 2U rackmount height, on-line no-brake protection, input power factor correction, hot-swappable batteries, and more. The Axxium Rackmount UPS is designed to provide reliable on-line high frequency double-conversion power protection for Internetworking equipment, midrange computer systems, telecommunication systems, central data processing and manufacturing process control. The compact system stands only 2U high (3.5 inches). It can also be wall mounted, with brackets and hardware included with every unit. According to Best Power, the Axxium is ideal for mission-critical applications because of its extended runtime with optional external batteries. External battery cabinets, at only 2U high each, can provide up to approximately two hours of full-load battery time.Available in 1000VA, 1500VA, 2kVA and 3kVA models, the Axxium Rackmount allows users to select the allowable input frequency range setting based on the requirements of connect equipment. The unit's BestDock communication slot enables a variety of connectivity options to allow for monitoring, management and graceful shutdown of key loads. Other standard features include built-in transient voltage surge suppression, hot-swappable batteries, easy-to-read LEDs, audible alarms and permanently attached input power cords.
