Description
APC Smart-UPS Ultra 8kVA Li-Ion with 5kVA Step-Down Transformer — SRTL8KRM4UT-5KTF
The SRTL8KRM4UT-5KTF pairs the APC Smart-UPS Ultra 8kW lithium-ion double-conversion UPS with a single SRTL 5kVA step-down transformer. This bundle is the right choice for 208V rack environments that need to protect a mix of 208V and 120V equipment — without adding a separate UPS or sourcing independent voltage conversion hardware. The 8kW UPS provides true online double-conversion power with the maintenance advantages of lithium-ion chemistry, while the bundled transformer adds protected 120V output capacity for standard NEMA 5-20R devices.
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
- 8,000VA/8,000W double-conversion online UPS — continuous power conditioning, zero transfer time
- Lithium-ion battery — up to 10-year lifespan, 30%+ lighter than comparable lead-acid UPS
- 4U rack/tower convertible chassis with auto-rotating LCD touch display
- Bundled 5kVA step-down transformer delivers protected 120V output from 208V UPS for mixed-voltage environments
- UPS outlets: 2x NEMA L6-20R, 2x NEMA L6-30R (208V); transformer adds: 8x NEMA 5-20R, 2x L6-20R, 1x L6-30R, 1x L14-30R
- Up to 10 SRTL180RM2UBP external battery packs supported for extended runtime
- EcoStruxure IT compatible for remote monitoring and centralized management

Ideal Applications and Industries
The SRTL8KRM4UT-5KTF bundle suits mid-size data centers and server rooms where a single 208V feed powers both high-density compute (208V) and standard network equipment or workstations (120V). Healthcare organizations protecting EMR servers alongside 120V medical workstations benefit from this single-UPS, dual-voltage approach. Manufacturing and industrial facilities running PLCs, industrial PCs, and 120V instrumentation from the same UPS feed reduce cabling complexity and battery management overhead compared to deploying two separate UPS units.
