Description
The APC Smart-UPS SRT 6000VA 208V (SRT6KXLTW) represents the pinnacle of high-density power protection for mission-critical enterprise environments. Utilizing an online double-conversion topology, this uninterruptible power supply (UPS) continuously conditions incoming utility power, delivering a pure sine wave output with zero transfer time to battery. With a robust 6000W/6000VA capacity, it is engineered to support high-draw server racks, network switches, and storage arrays, ensuring absolute business continuity during blackouts, brownouts, and voltage surges.
To understand who benefits most from this enterprise-grade power solution, here are five primary target audiences:
- IT and Network Administrators: Managing complex server rooms and wiring closets that require reliable, remote-manageable power backup to prevent data loss and hardware damage.
- Data Center Managers: Overseeing high-density rack environments where continuous uptime, high efficiency, and integration with platforms like EcoStruxure IT are critical.
- Healthcare and Laboratory Facilities: Protecting sensitive medical imaging equipment, diagnostic systems, and lab analyzers that cannot tolerate even a millisecond of power interruption.
- Industrial Automation Engineers: Safeguarding programmable logic controllers (PLCs) and manufacturing control systems operating in harsh electrical environments.
- Edge Computing and Telecom Operators: Ensuring uninterrupted operation of distributed edge nodes, cellular base stations, and fiber-optic network hubs.
Engineered with precise technical specifications, the SRT6KXLTW features a hardwired 3-wire (2PH + G) input supporting a nominal voltage of 208V (configurable to 240V) with an adjustable input voltage range of 100V to 275V under half load. The output configuration includes two NEMA L6-20R and three NEMA L6-30R outlets, alongside a hardwired 3-wire output. Physically, the unit measures 43.2 cm in height, 17.4 cm in width, and 71.9 cm in depth, weighing 61.23 kg. It utilizes the APCRBC140 replacement battery cartridge, which features sealed lead-acid technology and a typical recharge time of 1.5 hours. The system is certified under UL 1778, FCC Part 15 Class A, NOM, and is ENERGY STAR V2.0 compliant.
Operating the APC SRT6KXLTW is streamlined through its integrated Network Management Card 3 (NMC3), which provides secure remote monitoring and environmental sensing. Administrators can easily track battery health, load levels, and environmental temperature through a web browser or SNMP interface. In the event of an extended power outage, the included PowerChute Network Shutdown software orchestrates the graceful, unattended shutdown of physical servers, virtual machines, and hyperconverged infrastructure (HCI) clusters. The physical installation is highly versatile; while it ships as a tower configuration with detachable support feet, it is fully compatible with SRTRK2 (4-post) and SRTRK3 (2-post) rackmount rail kits for seamless integration into standard 19-inch IT enclosures.
When compared to standard line-interactive UPS systems, the online double-conversion design of the SRT6KXLTW offers superior protection. Line-interactive models exhibit a brief transfer time (typically 4 to 10 milliseconds) when switching to battery power, which can cause sensitive high-end servers or medical equipment to reboot. Furthermore, the SRT6KXLTW provides continuous voltage regulation without draining the battery, whereas line-interactive systems rely on battery power more frequently during minor voltage fluctuations, shortening overall battery lifespan. Compared to lower-capacity 3000VA models, this 6000VA unit provides double the power headroom and supports external battery packs for scalable runtime extension.
Here are answers to the most common technical queries regarding this uninterruptible power supply:
- What is the benefit of an online double-conversion UPS? It completely isolates connected equipment from utility power anomalies by converting AC power to DC, and then back to clean AC, ensuring zero transfer time and a perfect pure sine wave output.
- Can the runtime of the SRT6KXLTW be extended? Yes, this model supports scalable runtime by connecting external compatible battery packs to meet longer backup requirements during extended outages.
- What software is used for remote management and server shutdown? The UPS comes with PowerChute Network Shutdown, which integrates with the embedded Network Management Card to safely shut down physical and virtualized IT infrastructures.
- What are the input and output connection types? The input is a hardwired 3-wire (2-phase + ground) connection, while the output features two NEMA L6-20R outlets, three NEMA L6-30R outlets, and a hardwired 3-wire connection.
- What is the warranty coverage for this system? APC provides a comprehensive 3-year warranty on the UPS chassis and electronics, and a 2-year warranty on the internal sealed lead-acid battery.
