APC Smart-UPS Ultra 3kVA Lithium-Ion 1U 230V

The APC Smart-UPS Ultra 3kVA Lithium-Ion 1U 230V (SRTL3KRM1UIC) is a true online double-conversion UPS delivering continuous, conditioned power with zero transfer time to battery. Built around an advanced lithium-ion battery chemistry, the unit achieves a dramatically reduced footprint compared to traditional VRLA-based equivalents, occupying just 1U of rack space while supporting up to 3kVA / 2700W of connected load. The integrated Network Management Card slot and SmartConnect cloud portal enable remote monitoring, firmware updates, and predictive battery health analytics without requiring additional hardware.

Lithium-ion cell technology provides a substantially longer service life and a significantly lighter physical weight than lead-acid alternatives, reducing both rack loading and the frequency of battery replacement cycles. The unit supports hot-swappable external battery modules (SRT model series compatible) for scalable runtime extension without powering down connected equipment. Intelligent battery management continuously monitors cell temperature and charge state, maximising usable life and providing advance warning of degradation.

The Smart-UPS Ultra is engineered for dense, space-constrained deployments including edge compute nodes, micro data centres, colocation suites, and enterprise server rooms where rack real estate is at a premium. Its pure sine wave output protects sensitive active PFC power supplies found in modern servers, storage arrays, and networking equipment. Adjustable voltage-sensitivity settings, configurable outlet control, and broad input voltage window allow the unit to operate effectively across varied power environments without switching to battery unnecessarily.

Ideal for

• Protecting 1U and 2U rack servers and associated storage in space-constrained enterprise server rooms where rack unit availability is critical
• Providing conditioned online UPS protection at edge compute and IoT gateway sites where lithium-ion longevity reduces on-site maintenance visits
• Supporting micro data centre and colocation deployments that require remote cloud-based monitoring and management via APC SmartConnect
• Safeguarding active PFC power supplies in high-density hyperconverged infrastructure nodes with pure sine wave output
• Enabling runtime extension at remote or unmanned sites through hot-swappable external battery module expansion without load downtime
• Replacing ageing VRLA rack UPS units in weight-restricted raised-floor environments where lithium-ion reduces structural rack loading
