On-Line UPS for 208 V racks

The APC Smart-UPS On-Line SRT5KRMXLT-A is a 5400 VA double-conversion UPS built for 208 V single-phase environments. It fits a 3U rack space and supplies pure sine-wave output to protect servers, network gear and storage arrays from power anomalies.

Pure sine output under continuous load

The unit delivers 208 V AC output with a pure sine waveform while running on battery or utility power. Double-conversion topology isolates connected equipment from voltage distortion and frequency drift during sustained operation. A 1.50 hour recharge brings the internal batteries back to full capacity after a discharge event.

Rack-mount install with NEMA locking outlets

The chassis mounts in a standard 3U rack and weighs 176.0 lbs, so two people or a lift are recommended. Four locking receptacles — two NEMA L6-20R and two NEMA L6-30R — secure power cords against accidental disconnect. A pre-installed network management card and SmartSlot enable remote monitoring; forgetting to configure SNMP or the dry-contact interface is the most common setup oversight.

Questions about this item

How much heat does the 5400VA unit add to a rack when running continuously?

The UPS draws up to 5400 VA at 208 V and weighs 176.0 lbs, so plan for the corresponding thermal load in a 3U space.

Which input plug or circuit must already be in place for the 208 V connection?

The unit requires a 208 V AC single-phase source that matches its input voltage range.

Will the L6-20R and L6-30R outlets power older 208 V gear without adapters?

It provides two NEMA L6-20R and two NEMA L6-30R receptacles, delivering pure sine-wave output at 208 V AC.
