NXT Power Integrity Max UPS Overview
The NXT Power Integrity Max UPS (NPTU4200-HO-N) supplies 4200 VA / 4200 W of isolated, online double-conversion power for larger hardwired facility installs. This IGBT rectifier-inverter pair and internal isolation transformer regenerate output continuously. A manual bypass allows servicing without interrupting the connected load.
Input is hardwired at 208 VAC; output delivers a hardwired 240/208/120 VAC tap set sized by an electrician. There's no plug or outlet on this model. RS-232, USB, and DB-9 dry contacts handle local monitoring, with an internal SNMP adapter optional for network alerts.
UL1778 listing and a three-year NXT Power warranty cover components and internal batteries. The same 192 VDC, sixteen-battery bus delivers a short, clean ride-through at this higher power level.

How to Choose the Right Hardwired Facility UPS
Sizing a hardwired Max UPS is a facility decision, not a plug-in one. Weigh these axes before you spec a unit:
- Capacity headroom — size above the combined facility load; the NPTU4200-HO-N supports up to 4200 W continuous.
- Isolation vs. standard backup — continuous double-conversion output stays isolated and regenerated at all times, with a manual bypass for service.
- Waveform — true sine wave output suits facility instrument and IT loads that reject stepped waveforms.
- Shutdown & communication — RS-232, USB, DB-9 dry contacts, and an optional SNMP adapter support monitored, networked shutdown.
- Site power — confirm 208 VAC hardwired facility distribution sized for 26 A; an electrician must terminate the connection.
Laboratory Applications
Larger equipment rooms and multi-rack instrument suites that exceed the NPTU2200-HO-N's capacity fit the NPTU4200-HO-N's 4200 W rating. Consolidated imaging, diagnostic, and IT infrastructure running on a shared hardwired feed benefits from continuously isolated, regenerated power. Manual bypass keeps that infrastructure live during scheduled maintenance.
Facilities with dedicated 208 VAC distribution built for heavier equipment loads are the intended fit. No wall outlet or portable cord is involved at this capacity tier, and a licensed electrician must terminate the hardwired connection.

Frequently Asked Questions
Does the NPTU4200-HO-N plug into a wall outlet?
No. It's a hardwired unit; a licensed electrician terminates both the 208 VAC input and the 240/208/120 VAC output.
What load can it support?
Up to 4200 VA / 4200 W continuous, powered from sixteen internal 12 V VRLA batteries.
What does the manual bypass do?
It routes power around the UPS electronics during service, keeping the connected load powered without interruption.
Does it support remote monitoring?
RS-232, USB, and DB-9 dry contacts 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.
