The HP DirectFlow (DF) Uninterruptible Power System (UPS) is a modular and scalable UPS that provides a high-density backup power solution for HP servers and storage. It features a separate power management unit that integrates the major stages of an UPS - charger, inverter and active filter - into a single compact unit that dramatically reduces both size and cost when compared to a traditional UPS. The DF UPS provides up to 15kVA (3U) or 19.9kVA (5U) of power, utilizing 1U (Lithium-Ion) or 3U (Valve Regulated Lead Acid) battery pack options. HP's DF UPS technology creates a highly efficient backup power solution by removing the active front-end AC/DC power conversion steps, delivering an efficiency exceeding 99%. DF UPS technology also includes integrated Active Current Correction that enables power factor closer to unity in low-load conditions, providing clean power that ultimately lowers your power costs.
