1U lithium UPS — frequently asked questions

What is a 1U lithium UPS?
A 1U lithium UPS fits a single rack unit and uses LiFePO4 batteries, giving longer life and heat tolerance than lead-acid in a slim rackmount form factor. The J90 is Xtreme Power's 1U lithium UPS.
What does remote outlet control do on the J90?
It lets you power-cycle individual outlets remotely, so you can reboot a hung device in the rack without a site visit.
What loads does the J90 1U UPS protect?
Network switches, routers, servers, and edge gear in racks that need compact, long-life backup with remote management.
Why choose lithium for a 1U rack UPS?
LiFePO4 lasts far longer, runs cooler, and needs fewer replacements than lead-acid — ideal for warm, unattended racks and closets.
How much runtime does the J90 1U UPS provide?
Runtime scales with the model and load, and lithium recharges quickly for fast turnaround after an outage.
