APC SRT1000RMXLA 1000 VA Online UPS 120 V
Overview :
The APC SRT1000RMXLA is a double-conversion on-line uninterruptible power supply (UPS) that continuously conditions and provides backup power to critical IT equipment. It is typically deployed by data centre engineers, network administrators, and IT technicians to protect low-to-moderate load servers, storage, and networking hardware from utility power disturbances and outages in 120 V single-phase distribution environments. ([turn0search0], [turn0search1])
With a 1000 VA / 900 W capacity and true double-conversion topology, this UPS isolates connected loads from input voltage variations, frequency deviations, and electrical noise while delivering pure sine-wave output. The topology also supports internal bypass to maintain load continuity during internal maintenance or failure conditions. ([turn0search23], [turn0search3])
Mechanically, the unit is designed for 19″ rackmount installation (2U) with included rail kit and can also be used in tower form. The compact 2U height makes it suitable for IDF/MDF racks, edge cabinets, or small server rooms where space optimisation is crucial. ([turn0search14], [turn0search5])
Front and rear I/O includes six NEMA 5-15R outlets for distributed load connection and a NEMA 5-15P input for standard 120 V mains supply. Communications include serial (RJ45), USB, and SmartSlot interfaces for optional UPS network management cards and integration with APC PowerChute or centralized management platforms. Online efficiency is ENERGY STAR certified, meaning efficient operation across typical loads. ([turn0search4], [turn0search23])
Typical internal runtime at full load is ~9-10 min and at half load ~25-27 min, enabling orderly shutdowns or transition to standby generators during short outages. External battery packs are supported for extended runtime when necessary. ([turn0search23], [turn0search3])
This UPS is not intended for 208 V/230 V distribution without the correct regional variant and is best suited for environments where backup is required for minutes rather than hours without external batteries.
