NXT Power Integrity Max LT UPS Overview
The NXT Power Integrity Max LT UPS (NPTU3000-O-N) supplies 2700 VA / 2430 W of isolated, online double-conversion power. It's the largest 120 VAC model in the Max LT line. This continuous double-conversion topology regenerates output from an isolated DC bus, eliminating transfer gaps during mains events.
A fixed NEMA L5-30P cord draws from a dedicated 120 VAC circuit, and output splits across one L5-30R plus six NEMA 5-20R receptacles. 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. AC-DC-AC efficiency reaches 84%, keeping continuous-duty heat output manageable in a dedicated equipment room.

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 NPTU3000-O-N supports up to 2430 W continuous.
- Isolation vs. standard backup — continuous double-conversion output stays isolated and regenerated at all times, unlike backups that only switch 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 dedicated 120 VAC circuit with a NEMA L5-30 receptacle.
Laboratory Applications
The heaviest single-circuit instrument loads in the Max LT line fit the NPTU3000-O-N's 2430 W rating. Preparative LC systems, multi-detector GC-MS stacks, and equipment rooms consolidating several racks onto one feed all run on continuously isolated, regenerated power. A dedicated L5-30 circuit keeps this unit separate from lighter general-purpose loads.
IT infrastructure sized for a full instrument suite draws comparable steady current. Continuous double conversion removes the brief switchover gap that a simpler backup would still expose that infrastructure to.
