Description
APC Smart-UPS Ultra 10kVA Li-Ion with Two 5kVA Step-Down Transformers — SRTL10KRM4UT-5KTF2
The SRTL10KRM4UT-5KTF2 bundles the APC Smart-UPS Ultra 10kW lithium-ion double-conversion UPS with two SRTL 5kVA step-down transformers. This combination solves one of the most common challenges in 208V power environments: connecting 120V equipment without sourcing additional UPS capacity or separate voltage conversion hardware. With this bundle, a single 10kW UPS provides protected 208V output for high-voltage devices while the two transformers simultaneously deliver protected 120V output — across a fully integrated rack deployment.
Why Lithium-Ion vs. Lead-Acid UPS?
| Factor | Lead-Acid (SRT) | Lithium-Ion (SRTL) |
|---|---|---|
| Battery Lifespan | 3–5 years | Up to 10 years |
| Weight | Significantly heavier | Up to 40–60% lighter |
| Recharge Time | 4–8 hours | Approximately 3 hours |
| Battery Replacement Cycles | 2–3x over 10 years | 0–1x over 10 years |
| Temperature Range | Narrow | Wider operating range |
Key Features
- 10kVA/10kW double-conversion online UPS — true online topology with zero transfer time
- Lithium-ion battery — up to 10-year lifespan, no routine battery swap needed during UPS operational life
- 4U rack/tower convertible chassis with auto-rotating LCD — adapts to rack or tower installation without reconfiguration
- Two bundled 5kVA step-down transformers — each provides 120V output from 208V UPS for mixed-voltage environments
- UPS outlets: 2x NEMA L6-20R and 2x NEMA L6-30R (208V native); each transformer adds 12x NEMA 5-20R (120V)
- Embedded Network Management Card for EcoStruxure IT integration, remote monitoring, and PowerChute shutdown
- Up to 10 SRTL180RM2UBP external battery packs supported for extended runtime
- EcoStruxure Ready — compatible with third-party centralized management platforms

Ideal Applications and Industries
This bundle is purpose-built for data centers and server rooms running mixed-voltage equipment — where 208V is the primary feed but legacy servers, KVM switches, workstations, or networking gear require 120V. Colocation facilities providing managed power to tenants with diverse equipment benefit from having 120V and 208V protected outlets from a single UPS. Healthcare data centers protecting imaging workstations, clinical servers, and 120V medical peripherals from the same UPS circuit benefit from the simplified cabling and single-vendor warranty. Government and defense facilities standardizing on APC infrastructure can deploy this bundle to support both high-power compute and standard 120V office equipment under one power protection unit.
Reduce Battery Maintenance Across Your Fleet
Questyme helps data center managers and IT directors evaluate whether the SRTL10KRM4UT-5KTF2 bundle or individual components better fits their rack layout, power distribution strategy, and budget. We provide TCO comparisons between lead-acid SRT and lithium-ion SRTL deployments across multi-rack and multi-site environments.
