The Vertiv Liebert APS 20kVA Scalable to 20kVA N+1 208V Modular UPS (AS4D0NCXGNNXLKB) is an online double conversion UPS with up to 10 minutes full-load runtime designed for room or row-based applications. It offers redundancy and flexibility for the future while ensuring maximum power availability to your critical systems. The APS modules are hot-swappable FlexPower assemblies and battery modules that are quickly and easily installed or replaced without disrupting power. The addition of power capacity or battery modules as needed or pay as you grow design allows for better CAPEX/OPEX budget management. With high energy efficiency of up to 92%, it supports sustainability and reduces the total cost of ownership (TCO). It has intelligent battery management and can operate in a temporary overload state up to 200% load. For remote management and environmental monitoring, a Liebert IntelliSlot Unity Card (IS-UNITY-DP) comes factory installed for FREE Power Insight Software, and enables compatibility with Vertiv environmental monitoring sensors.
