NXT Power Integrity PRO Standard UPS Overview
The NXT Power Integrity PRO Standard UPS (NPTU1100-L-N) provides 1100 VA / 990 W of isolated backup power for larger instrument stacks. Four internal batteries extend runtime while the isolation transformer and pure sine wave inverter keep output clean. Two programmable outlet groups let critical and secondary loads shut down on separate schedules.
Isolation performance matches the rest of the Standard line: common-mode noise under 0.5 V, normal-mode noise under 10 V. A detachable IEC 320 cord and 50/60 Hz auto-sensing input simplify deployment across sites. USB, RS-232, and an optional SNMP slot cover monitored shutdown and remote alerts.
Every NPTU1100-L-N carries UL1778 listing and NXT Power's three-year warranty on the chassis, electronics, and batteries. Typical transfer time stays under 6 ms, well inside most instrument power supplies' ride-through window.

How to Choose the Right Isolated UPS
Sizing a Standard-line UPS for lab electronics comes down to more than outage runtime. Weigh these axes before you spec a unit:
- Capacity headroom — size above the combined load; the NPTU1100-L-N supports up to 990 W continuous.
- Isolation vs. standard backup — four internal batteries and isolation together protect multi-module instrument stacks that a standard backup can't clean or carry.
- Waveform — pure sine wave output avoids the stepped waveforms that disrupt sensitive detector power supplies.
- Shutdown & communication — USB, RS-232, and an optional SNMP slot support monitored, staged shutdown.
- Site power — confirm a 120 VAC 50/60 Hz circuit; the detachable IEC 320 cord simplifies service.
Laboratory Applications
Multi-module analytical systems draw enough current that the 1100 VA rating becomes the practical minimum. LC-MS front ends, multi-detector GC stacks, and paired balance-and-printer setups run within the 990 W envelope. Isolation keeps ground loops off shared-bench wiring.
Server racks supporting instrument data pipelines and networked LIMS terminals draw similarly steady current. Programmable outlet groups keep acquisition hardware live while auxiliary displays or printers shed load first.

Frequently Asked Questions
What load can the NPTU1100-L-N support?
Up to 1100 VA / 990 W continuous, backed by four (4) 12 V / 7 Ah VRLA batteries.
Why four batteries instead of two?
The higher capacity rating needs more stored energy; four batteries deliver adequate runtime at the 990 W load level.
Can I stage shutdown across devices?
Yes, two programmable outlet groups allow independent sequencing.
What monitoring options exist?
USB and RS-232 are built in, with an intelligent slot for an optional SNMP adapter.
What's the warranty term?
Three years, covering the chassis, electronics, and internal batteries.
