J90-3kLiD vs APC Smart-UPS Ultra SRTL3KRM1UC
The Xtreme Power J90-3kLiD and APC Smart-UPS Ultra 3000VA (SRTL3KRM1UC) are compact 1U, 120V online lithium UPS systems for edge IT, networking, AV, and distributed infrastructure. Both deliver dense, high-efficiency power; meaningful differences emerge in battery chemistry, operating temperature, lifecycle cost, remote controllability, and procurement readiness. The comparison also applies to the network-card version, SRTL3KRM1UNC.
What the J90-3kLiD brings
- LiFePO₄ chemistry for improved safety and longevity
- Up to 50 °C (122 °F) operation for limited-cooling sites
- 15-year design life / 3,000–5,000 cycles
- Remote outlet-level control available with Web/SNMP
- TAA compliant for federal and regulated procurement
- Six-year warranty (USA and Canada) covering electronics and battery

Both platforms are online double-conversion and deliver pure sine wave output in all modes. Competitor specifications vary by SKU and region; verify against current APC documentation.
Choosing between them
The J90-3kLiD is built for high-temperature edge and telecom deployments, unattended or hard-to-access locations, sites where battery replacement is costly or disruptive, government and regulated projects, and deployments requiring remote outlet-level control.
Choose the J90-3kLiD if you need
- Reliable operation in hot or poorly cooled environments
- Long-life LiFePO₄ batteries with fewer replacements
- TAA compliance for procurement
- Remote monitoring with optional outlet-level control
- A UPS optimized for edge, AV, and distributed IT
The Smart-UPS Ultra 3000VA may fit if you need
- Alignment with an existing APC / Schneider Electric ecosystem
- Native cloud-based monitoring (SmartConnect)
- Climate-controlled IT rooms with consistent cooling
J90-3kLiD vs SRTL3KRM1UC: common questions
What is the Xtreme Power equivalent of the APC SRTL3KRM1UC?
The J90-3kLiD. Both are 1U, 120V, 3000 VA online double-conversion lithium UPS systems with a NEMA L5-30P input plug, so the J90-3kLiD uses the same rack space and the same 30 A circuit. APC rates the SRTL3KRM1UC at 2880 W; the J90-3kLiD is rated 2700 W.
How do the J90-3kLiD and SRTL3KRM1UC compare on operating temperature?
The J90-3kLiD delivers full rated output to 50 °C (122 °F). The SRTL3KRM1UC is rated to 40 °C (104 °F), which matters in IDF closets, telecom rooms and industrial enclosures without dedicated cooling.
Does the SRTL3KRM1UC have individual outlet control?
No. The J90-3kLiD has individually controllable outlets through its optional Web/SNMP card, so a single locked-up device can be power-cycled remotely without dropping the rest of the rack.
Is the J90-3kLiD TAA compliant?
Yes. Every J90 is TAA compliant as standard, with Taiwan as the country of origin. APC offers TAA compliance only on select Smart-UPS Ultra part numbers.
What warranty comes with each?
The J90-3kLiD carries a 6-year warranty on electronics and battery in the USA and Canada. The SRTL3KRM1UC carries a 5-year warranty.
