NXT Power Integrity Max R/T UPS Overview
The NXT Power Integrity Max R/T UPS (NPTU1100-OR-N) supplies 1100 VA / 990 W of isolated, online double-conversion power from the same 2U rack-tower chassis as its siblings. Continuous double-conversion regenerates output power at all times, giving connected rack gear a zero-gap transfer during mains events. An internal isolation transformer strips common-mode noise before it reaches the rack.
Six NEMA 5-15R outlets cover standard rack equipment, and input defaults to 120 VAC with a 100 VAC option available. RS-232 and USB handle local monitoring, while an internal SNMP slot supports network alerts. Rack ears and tower feet ship in the box for either mounting style.
UL1778 listing and a three-year NXT Power warranty cover components and internal batteries on every unit. Three internal VRLA batteries form the 36 VDC bus, tuned for a short, clean ride-through rather than extended standby time.

How to Choose the Right Isolated Rack Tower UPS
Sizing a rack-tower UPS comes down to rack load and how it's isolated, not just runtime. Weigh these axes before you spec a unit:
- Capacity headroom — size above the combined rack load; the NPTU1100-OR-N supports up to 990 W continuous.
- Isolation vs. standard backup — continuous double-conversion output stays isolated and regenerated at all times, not only after a transfer event.
- Waveform — true sine wave output suits networking and instrument power supplies that reject stepped waveforms.
- Shutdown & communication — RS-232, USB, and an optional SNMP slot support monitored shutdown across a rack.
- Site power — confirm a 120 VAC circuit and 2U of rack space; power connects via a fixed NEMA 5-15P cord.
Laboratory Applications
Busier rack-mounted instrument and IT loads fit the NPTU1100-OR-N's step up in capacity. Multi-port switches, small server clusters, and instrument controllers sharing a rack stay within its 990 W rating while output remains isolated and regenerated. Racks that combine networking and analytical gear are where ground-loop noise causes the most trouble, and double conversion blocks it continuously.
Diagnostic imaging racks and multi-instrument benches with a heavier combined draw suit the same profile. Continuous double conversion protects equipment that faults on even a brief switchover, a common failure mode with simpler line-interactive backups.

Frequently Asked Questions
What load can the NPTU1100-OR-N support?
Up to 1100 VA / 990 W continuous, powered from three internal 12 V VRLA batteries.
How does double conversion differ from a standard rack UPS?
Output is continuously regenerated from an isolated DC bus rather than switched during an outage, so there's no transfer gap.
Does it mount in a standard rack?
Yes, it ships 2U with rack ears and tower feet included for either mounting style.
Does it support remote monitoring?
RS-232 and USB ports are standard, with an internal SNMP adapter available as an option.
How long is the warranty?
Three years, covering components and the internal batteries from the date of shipment.
