- Modular, Scalable Architecture: Modules come in 5–20 kVA capacity and scalable in 5 kVA increments with N+1 redundancy. With Pay-as-you-grow flexibility, add power or battery modules as demand increases without replacing the entire system.
- Dual Battery Chemistry Support:This industry-first UPS supports VRLA and Lithium-Ion in the same frame. Choose the battery technology that fits your budget and runtime needs today, with the ability to upgrade later without firmware changes.
- Hot-Swappable Modules: This user-replaceable power, battery, and control modules allow you to perform maintenance or upgrades without downtime, providing continuous availability.
- Built-In Redundancy: It has module-level N+1 redundancy for power and battery, which eliminates single points of failure, so critical loads remain protected even during maintenance or component failure.
- Online Double Conversion Topology: Its true online design with zero transfer time and internal automatic bypass protects your devices against all power anomalies (sags, surges, harmonics) and provides clean, conditioned power for sensitive IT loads.
- High Output Power Factor: With 0.9 power factor per module (5 kVA / 4.5 kW), it delivers more usable power in the same footprint, optimizing rack and floor space.
- Intelligent Battery Management: It has temperature-compensated charging for VRLA and integrated BMS for Lithium-Ion. This management extends battery life, reduces replacement costs, and provides real-time health monitoring for predictive maintenance.
- Flexible Runtime Options: Add battery modules or external battery cabinets for extended backup. Scale runtime without taking the load offline, which is ideal for evolving site requirements.
- Remote Monitoring & Control: It comes with factory-installed Vertiv™ Liebert® IntelliSlot™ RDU120 card with Vertiv™ LIFE™ Services. This enables secure remote management, predictive analytics, and proactive service to maximize uptime.
- Compact, Versatile Deployment: It allows tower or rack configuration with optional PODs for varied outlet types. This fits diverse IT and edge environments with simplified installation and adaptability.
Specifications
Vertiv Liebert® APS UPS supports both VRLA and lithium-ion battery strings in the same frame. VRLA remains a practical choice for shorter runtime or cost-sensitive environments, while lithium-ion offers longer useful life, faster recharge, and better performance at higher operating temperatures. Both battery types integrate seamlessly to support flexible runtime, cost, and maintenance planning across different sites.
