J90-2kLiD vs SRTL2K2RM1UC: common questions
What is the Xtreme Power equivalent of the APC SRTL2K2RM1UC?
The J90-2kLiD. Both are 1U, 120V online double-conversion lithium UPS systems. APC rates the SRTL2K2RM1UC at 2200 VA / 1950 W; the J90-2kLiD is rated 2000 VA / 1800 W. For loads above 1800 W, step up to the J90-3kLiD.
How do the J90-2kLiD and SRTL2K2RM1UC compare on operating temperature?
The J90-2kLiD delivers full rated output to 50 °C (122 °F). The SRTL2K2RM1UC is rated to 40 °C (104 °F), which matters in IDF closets, telecom rooms and industrial enclosures without dedicated cooling.
Does the SRTL2K2RM1UC have individual outlet control?
No. The J90-2kLiD 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.
Can both be wall mounted?
Yes. The J90-2kLiD ships with wall-mount brackets, and the Smart-UPS Ultra supports rack, tower, wall, ceiling and desk mounting.
Is the J90-2kLiD 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 J90-2kLiD carries a 6-year warranty on UPS and battery in the USA and Canada. The SRTL2K2RM1UC carries a 5-year warranty.
