Double-Conversion Online UPS

The Eaton 9PX3K3UN is a 3000 VA, 3000 W double-conversion online UPS that delivers continuous sine-wave power at 208 V to connected equipment. Its topology isolates loads from utility disturbances without switching delay, making it suitable for servers, storage arrays and network infrastructure that cannot tolerate transfer time.

Sustained Load Behaviour

Because the inverter supplies the load at all times, the unit maintains rated output during extended brownouts or over-voltage events without draining the battery prematurely. The 3000 W rating matches the VA rating, so the full capacity is available for unity-power-factor loads such as modern switch-mode power supplies.

Rack-or-Tower Mounting and Outlets

The 3U chassis weighs 123 and can be installed in a standard rack or used as a tower, with the display orienting automatically for either position. Two NEMA L6-20R and two NEMA L6-30R receptacles provide locking connections for high-current PDUs or direct equipment feeds, while the single L6-30P input requires a matching 30 A branch circuit.

Questions about this item

How much heat does the 3000 W double-conversion UPS put out when it runs continuously?

The unit delivers 3000 W to the load; internal losses appear as heat, so expect typical online-UPS efficiency losses at full load.

Which input plug must my facility provide for the L6-30P connection?

A single NEMA L6-30P receptacle on a 30 A, 208 V circuit is required to power the UPS.

Can I keep using my existing L6-20R equipment with the two L6-20R outlets on this UPS?

Yes, the two NEMA L6-20R outlets accept standard L6-20P plugs from your current 208 V devices.
