NXT Power Integrity Max LT UPS Overview
The NXT Power Integrity Max LT UPS (NPTU2000-O-N) delivers 1920 VA / 1728 W of isolated, online double-conversion power for equipment that outgrows a rack-tower unit. Continuous double conversion regenerates output from an isolated DC bus, so connected systems see zero transfer gap during a mains event. Six internal batteries form a 72 VDC bus sized for a clean, dependable ride-through.
A fixed NEMA 5-20P cord draws from a standard 120 VAC circuit, and output splits across one L5-30R plus six NEMA 5-20R receptacles. Where site power requires it, a 100 VAC configuration is also available. RS-232, USB, and an optional internal SNMP adapter cover local and networked monitoring.
UL1778 listing and NXT Power's three-year warranty cover components and internal batteries. Efficiency reaches 84% AC-DC-AC, keeping heat output manageable in an equipment room running continuously.

How to Choose the Right Isolated Max LT UPS
Sizing a Max LT UPS comes down to facility load and available circuits. Weigh these axes before you spec a unit:
- Capacity headroom — size above the combined load; the NPTU2000-O-N supports up to 1728 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 instrument and IT power supplies that reject stepped waveforms.
- Shutdown & communication — RS-232, USB, and an optional SNMP adapter support monitored, networked shutdown.
- Site power — confirm a 120 VAC circuit and NEMA 5-20 receptacle; a 100 VAC configuration is available where needed.
Laboratory Applications
Larger analytical systems that a desktop or rack-tower unit can't carry fit the NPTU2000-O-N's 1728 W rating. GC-MS and LC-MS front ends, along with multi-instrument benches drawing steady combined current, run on continuously isolated, regenerated power. Equipment rooms consolidating several instrument racks see the same benefit at a shared point of use.
IT infrastructure supporting instrument data pipelines, including small server clusters and network cores, draws similarly steady load at this capacity. Continuous double conversion protects that infrastructure from the brief switchover gaps that simpler backups can't fully eliminate.

Frequently Asked Questions
What load can the NPTU2000-O-N support?
Up to 1920 VA / 1728 W continuous, powered from six internal 12 V VRLA batteries.
How does double conversion differ from a standard UPS?
Output is continuously regenerated from an isolated DC bus rather than switched during an outage, so there's no transfer gap.
What outlets does it provide?
One NEMA L5-30R and six NEMA 5-20R receptacles, fed from a fixed NEMA 5-20P input cord.
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.
