Model SRT1000RMXLA-NC

  • Pure sine wave output protects sensitive equipment
  • 1000 VA / 900 W capacity supports critical loads
  • 2U rack-mount form fits standard cabinets
  • 6 NEMA 5-15R outlets power multiple devices
  • 5 min runtime at full load, 25.4 min at half load

Purpose and audience

The APC Smart-UPS SRT 1000VA 900W rack-mount UPS delivers pure sine-wave output to protect servers, network switches and storage arrays in 120 V environments. IT professionals and network administrators who need continuous uptime for critical electronics will find its on-line double-conversion topology suited to that role. It is not intended for desktop workstations that only require basic standby protection.

Input and output limits

The unit accepts 80 to 150 V at 40 to 70 Hz through a NEMA 5-15P plug and supplies 120 V at 50 or 60 Hz ± 3 Hz to six NEMA 5-15R outlets. Surge protection is rated at 480 joules. Runtime falls to 10.5 minutes at the full 900 W load and extends to 25.4 minutes at half load, so plan connected equipment accordingly.

Installation and common issues

The 2U chassis mounts in standard racks and the pre-installed network management card enables remote monitoring via RJ-45 10/100, serial, USB or Smart-Slot connections. Battery replacement uses the APCRBC155 cartridge and requires a three-hour recharge after installation. Ensure the rack circuit can supply the 5-15P inlet and verify outlet count matches your device plugs before deployment.

Questions about this item

Which capacity fits a 900 W load — the 1000 VA model or a smaller unit?

The SRT1000RMXLA-NC is rated 1000 VA / 900 W; a smaller VA rating would not support a 900 W load.

What does the 10.5-minute runtime at full load mean for my rack equipment?

With all six outlets drawing 900 W total, the battery will power the rack for 10.5 minutes before shutdown.

What management does the RJ-45 10/100 port and Smart-Slot actually provide?

The RJ-45 10/100 port gives network monitoring via the preinstalled card; the Smart-Slot accepts optional accessories for extra protocols.
