Eaton 9PX 5500VA Online UPS

The Eaton 9PX 5500VA is an online double-conversion uninterruptible power supply rated at 4900 W. It accepts 120 V or 208 V input through an L14-30P plug and delivers power via six 5-20R receptacles, one L6-30R, one L14-30R and hard-wired terminals. A Cybersecure network card enables remote monitoring and management.

Suits racks or towers needing 4900 W online

This unit fits 4U rack spaces using the included four-post rail kit or stands as a tower on the supplied pedestals. It protects servers, networking gear and storage that require continuous sine-wave output with zero transfer time. Buyers who need a lower power rating or a line-interactive topology should consider other models.

4900 W double-conversion capacity

The 4900 W rating is the single figure that determines whether this UPS can support your connected load. If the total equipment draw exceeds this value the unit will overload; if it is comfortably below, the UPS will provide full online protection with extended-run capability.

Questions about this item

What input receptacle must my building provide for the L14-30P plug on this UPS?

The unit ships with an L14-30P input cord, so the facility needs a matching 30 A, 120/208 V three-phase receptacle.

Can I keep using my existing 5-20R and L6-30R equipment with the output sockets on this unit?

Yes, the rear panel includes six 5-20R outlets and one L6-30R outlet alongside the L14-30R and hardwired terminals.

How do I confirm the double-conversion topology is active after I power it on?

The front LCD will show "Online" mode and display input and output voltages locked at 120/208 V with zero transfer time.
