J90i-3kLiD vs SRTL3KRM1UWC: common questions
What is the Xtreme Power equivalent of the APC SRTL3KRM1UWC?
The J90i-3kLiD. Both are 1U, 208/230V online double-conversion lithium UPS systems. APC rates the SRTL3KRM1UWC at 3000 VA / 3000 W; the J90i-3kLiD is rated 3000 VA / 2700 W. If your real-power load is close to 2700 W, size with headroom or split the load.
How do they compare on operating temperature?
The J90i-3kLiD is rated to 50 °C (122 °F); the SRTL3KRM1UWC is rated to 40 °C (104 °F). That matters in IDF closets, telecom rooms and industrial enclosures without dedicated cooling.
Does the SRTL3KRM1UWC have individual outlet control?
No. The J90i-3kLiD has individually controllable outlets through its optional Web/SNMP card, so one locked-up device can be power-cycled remotely without dropping the rest of the rack.
Does this comparison apply to other Smart-UPS Ultra part numbers?
Yes. It also applies to other regional and network-card versions of the 3000VA Ultra, which share the same Smart-UPS Ultra platform.
Is the J90i-3kLiD TAA compliant?
Yes. Every J90i is TAA compliant as standard. APC offers TAA compliance only on select Smart-UPS Ultra part numbers.
What warranty comes with each?
The J90i-3kLiD carries a 6-year warranty on electronics and battery in the USA and Canada, and 2 years depot elsewhere. The SRTL3KRM1UWC carries a 5-year warranty.
