Rackmount UPS for 208V Server Loads

The APC Smart-UPS On-Line SRT5KRMXLT delivers 5.4 kVA and 4250 W of double-conversion sine-wave power in a 3U rackmount chassis. It suits server rooms and network closets that require continuous clean power for critical 208 V equipment.

Verify 30 A Service and L6-30P Feed

Confirm the site provides a 208 V single-phase circuit terminated with a NEMA L6-30P plug. The unit draws up to 30 A and occupies 3U of rack depth; ensure the rack can support the installed weight and that clearance allows the rear outlets and interface ports to be accessed.

Network Card and Rail Kit Accelerate Deployment

A pre-installed network management card enables SNMP and web monitoring through the RJ-45 10/100 port, while the SmartSlot remains open for additional accessories. The included rail kit, mounting brackets and hardware let two people secure the chassis without sourcing separate sliding rails.
