APC Smart-UPS Ultra 5kVA 1U Lithium UPS

The APC Smart-UPS Ultra 5kVA 1U Lithium (SRTL5KRM1UI) is a rack-mount uninterruptible power supply engineered for high-density deployment in space-constrained environments. Built around a lithium-ion battery chemistry, it delivers 5000VA / 4600W of online double-conversion power protection in a single rack unit, making it one of the most power-dense 1U UPS solutions available for enterprise and edge infrastructure. The lithium-ion cells offer a significantly longer service life and faster recharge cycle compared to traditional VRLA designs, while the unit's slim 1U form factor enables high-density rack configurations without sacrificing runtime or output capacity.

The Smart-UPS Ultra operates in true online double-conversion mode, ensuring complete electrical isolation between the utility input and the connected load. This topology continuously regenerates clean, regulated power, eliminating the impact of sags, surges, brownouts, overvoltages, and electrical noise on sensitive equipment. The unit supports an adjustable output voltage and frequency, making it suitable for loads with strict power quality requirements. Network management is facilitated through a built-in Network Management Card interface, enabling remote monitoring, automated shutdown, and integration with data center infrastructure management (DCIM) platforms via SNMP, Modbus, and EcoStruxure IT.

Designed with the modern edge data center and distributed enterprise IT environment in mind, the SRTL5KRM1UI is optimised for compute, networking, and storage workloads where rack space is at a premium and power reliability is non-negotiable. Its lithium-ion architecture supports hot-swappable battery modules, reducing planned maintenance windows, and the unit ships with APC's SmartConnect cloud monitoring capability, allowing IT teams to proactively track UPS health and receive alerts without requiring on-site presence. The combination of compact physical footprint, high watt-density output, and intelligent management positions this UPS as a fit-for-purpose solution for telco edge nodes, branch office server rooms, and hyperconverged infrastructure deployments.

Ideal for

• Edge data center nodes requiring maximum power protection in a single rack unit with minimal floor or rack space overhead
• Branch office and remote site IT closets hosting hyperconverged infrastructure, where lithium-ion longevity reduces the frequency of on-site battery service visits
• Telco and network aggregation racks supporting routers, switches, and SD-WAN appliances that demand clean, regulated double-conversion power
• High-density compute clusters in colocation facilities where per-rack power budgets are fixed and every rack unit carries a premium
• Distributed retail or healthcare IT environments where remote UPS monitoring via SmartConnect cloud reduces dependency on local IT staff for power infrastructure oversight
• Refresh of legacy VRLA-based UPS deployments where reduced battery footprint, longer service intervals, and faster recharge times improve total operational efficiency
