APC Smart-UPS Ultra On-Line Li-Ion 5kVA 1U Rack/Tower

The APC Smart-UPS Ultra On-Line Li-Ion 5kVA 1U Rack/Tower (SRTL5KRM1UC) is a true double-conversion online UPS built around lithium-ion battery technology, delivering continuous sinusoidal AC output with zero transfer time to battery. Its on-line topology ensures that connected loads are always powered from the inverter, providing complete isolation from all input power anomalies including sags, surges, harmonics, and frequency deviations. The 1U rack/tower convertible form factor enables exceptionally high power density deployments, fitting a full 5kVA/5kW capacity into a single rack unit for space-constrained environments.

Lithium-ion chemistry at the core of this unit yields a significantly longer service life compared to traditional valve-regulated lead-acid designs, with reduced weight that simplifies installation and handling in high-density rack environments. The intelligent battery management system continuously monitors cell health, temperature, and state of charge, enabling predictive replacement alerts and supporting optional hot-swap external battery modules (EBM) for extended runtime without powering down the load. Network Management Card 3 (NMC3) connectivity is included, providing real-time monitoring, event logging, and remote management via HTTPS, SNMPv1/v3, and Modbus TCP.

Designed for edge computing nodes, distributed IT infrastructure, and high-density server rack deployments, the SRTL5KRM1UC supports a wide input voltage window and adjustable input voltage sensitivity to accommodate challenging power environments. The unit is compatible with APC EcoStruxure IT for cloud-based infrastructure monitoring and integrates with leading DCIM and virtualization platforms through downloadable PowerChute software, making it well-suited for organizations requiring granular power event data, automated graceful shutdown, and compliance-grade power quality reporting.

Ideal for

• Edge data center and remote IT closet deployments where rack space is critically limited and 1U power density is required for 5kVA loads
• High-density blade server and hyperconverged infrastructure racks demanding continuous double-conversion protection with zero transfer time
• Distributed enterprise branch office server rooms requiring intelligent remote monitoring and management via integrated NMC3 over existing network infrastructure
• Telecommunications and network equipment enclosures where extended runtime via hot-swappable external battery modules is needed without planned downtime
• Healthcare and financial services environments mandating clean, regulated sinusoidal output and detailed power quality event logging for compliance purposes
• Colocation and managed service environments where reduced UPS weight and lithium-ion longevity lower total operational burden across large numbers of deployed units
