APC Smart-UPS Ultra On-Line 5kVA 1U Rack/Tower Lithium-ion UPS

The APC Smart-UPS Ultra On-Line 5kVA 1U Rack/Tower Lithium-ion UPS (SRTL5KRM1UWNC) represents a significant architectural leap in compact power protection, delivering true double-conversion on-line topology in an industry-leading 1U rack form factor. By integrating lithium-ion battery technology in place of traditional VRLA chemistry, the unit achieves approximately double the power density of legacy Smart-UPS equivalents of comparable VA rating, making it purpose-built for space-constrained data center refresh and edge deployments where every rack unit is at a premium. The on-line double-conversion design ensures zero transfer time to battery, providing continuous conditioned output voltage that is fully isolated from input anomalies including sags, surges, and frequency deviations.

The SRTL5KRM1UWNC operates at a 5000VA / 4500W power capacity with a unity-adjacent 0.9 power factor output, supporting a wide range of modern IT loads including high-density blade servers, hyperconverged infrastructure nodes, and networking equipment. The embedded lithium-ion battery system offers substantially extended service life compared to VRLA alternatives—typically three to five times longer cycle life—along with a reduced weight profile that eases physical installation in both rack and tower orientations. The unit supports an optional extended battery module (EBM) ecosystem for configurable runtime expansion without requiring a larger chassis footprint.

Network manageability is a core design pillar of this model. The included network management card slot supports APC's SmartConnect cloud management platform and is compatible with NMC3 network management cards, enabling remote monitoring, configuration, and alerting through Schneider Electric's EcoStruxure IT infrastructure management ecosystem. Outlet-level switching, configurable load shedding, and compatibility with PowerChute Network Shutdown software facilitate automated graceful shutdown sequences for virtualized and physical server environments, making this UPS well suited to enterprise data centers, colocation deployments, and distributed enterprise edge sites where intelligent power management is operationally critical.

Ideal for

• High-density data center rack refresh: replacing aging tower or 2U+ UPS units with a 1U lithium-ion solution to reclaim rack space for additional compute or storage nodes
• Edge and distributed enterprise sites: providing on-line double-conversion power protection at branch offices, retail locations, or remote infrastructure closets where floor and rack space are severely limited
• Hyperconverged infrastructure (HCI) protection: safeguarding HCI clusters such as Nutanix, VMware vSAN, or Microsoft S2D nodes that require zero-transfer-time power conditioning to prevent storage and VM corruption
• Colocation and multi-tenant environments: enabling tenant-level intelligent power monitoring and remote outlet control via NMC3 and EcoStruxure IT without requiring on-site intervention
• Virtualization host protection with automated shutdown: integrating with PowerChute Network Shutdown to orchestrate graceful hypervisor and guest VM shutdown sequences during extended outages, protecting data integrity
• Telecom and network equipment rooms: delivering conditioned, frequency-stable power to core routing, switching, and unified communications equipment where input power quality from utility feeds may be inconsistent
