Lithium UPS Alternative for AV Equipment Racks
The Xtreme Power J90-1.5kLi is a compact 1U lithium rackmount UPS designed for IT infrastructure, AV equipment racks, and edge computing environments requiring reliable online double-conversion power protection.
AV integrators and engineers evaluating the Middle Atlantic NEXSYS 1500 UPS (UPX-RLNK-OL1500R-2) often search for a lithium UPS alternative that reduces battery maintenance while improving rack efficiency.
The NEXSYS 1500 UPS provides similar power capacity but utilizes sealed lead-acid batteries and a larger 2U rackmount chassis.
Both platforms deliver continuous conditioned power. However, the J90-1.5kLi delivers higher rack power density, longer battery service life, and reduced maintenance through lithium battery technology and a compact 1U design.

UPS for AV Equipment Racks
AV equipment racks used in conference rooms, studios, broadcast facilities, and integrated AV systems require reliable backup power to prevent system shutdowns during power disturbances.
UPS platforms such as the Middle Atlantic NEXSYS series are commonly used to support:
- AV processors
- amplifiers
- control systems
- network switches
The Xtreme Power J90-1.5kLi provides a compact 1U lithium UPS alternative that delivers higher rack power density, longer battery service life, and reduced maintenance compared with traditional lead-acid UPS systems.
Because AV racks often operate in equipment closets or cabinets with limited cooling, the 50°C operating capability of the J90 platform provides additional deployment flexibility.
Ideal Applications
The J90-1.5kLi lithium UPS is well suited for:
- AV equipment racks and integrated rack systems
- conference room and boardroom AV installations
- network closets and IDF/MDF rooms
- edge computing deployments
- telecom racks and distributed IT systems
