Description
In today's data-driven landscape, even a millisecond of power disruption can corrupt critical databases, halt medical laboratory diagnostics, or crash enterprise networks. The APC Smart-UPS SRT 3000VA stands as a premier defense mechanism, offering high-density, double-conversion online power protection. Engineered for high-availability environments, this 2700W pure sine wave UPS ensures that connected devices receive continuous, clean electricity with zero transfer time during utility power failures. Its versatile rack/tower convertible form factor and scalable runtime options make it an indispensable asset for safeguarding mission-critical infrastructure.
This robust power protection system is engineered to meet the demanding requirements of several key sectors:
- Enterprise IT Administrators: Managing server rooms, network closets, and storage area networks (SAN) that require uninterrupted uptime and clean power.
- Medical and Laboratory Technicians: Operating highly sensitive diagnostic machinery, lab instruments, and life-science equipment where voltage fluctuations can ruin test results.
- Edge Computing and Telecom Operators: Running remote distributed infrastructure, cellular base stations, and VoIP networks that demand remote management and high reliability.
- Light Industrial and Automation Engineers: Protecting programmable logic controllers (PLCs) and automated assembly lines from industrial power sags and surges.
- Small-to-Medium Businesses (SMBs): Seeking a centralized, high-capacity power backup solution to protect core business servers and database systems.
The technical architecture of this uninterruptible power supply reflects its enterprise-grade engineering:
- Power Capacity: 3000 VA / 2700 Watts
- Topology: Double-Conversion Online with Pure Sine Wave output
- Input Voltage: 208V nominal (adjustable from 100V to 275V under half-load conditions)
- Output Voltage: Configurable for 208V or 240V single-phase output
- Input Connection: NEMA L6-20P plug with a 1.8-meter (6-foot) heavy-duty power cord
- Output Receptacles: Two NEMA L6-20R and one NEMA L6-30R outlets
- Battery System: 96V sealed lead-acid battery with a 3-hour typical recharge time and 3-to-5 year lifespan
- Physical Dimensions: 432 mm (Height) x 85 mm (Width) x 635 mm (Depth); Net Weight of 31.3 kg
- Connectivity & Management: USB port, Serial port, and one open SmartSlot for network management cards
- Surge Protection: Rated for 340 Joules of surge energy suppression
Deploying the APC SRT3000XLTW in a server rack or as a standalone tower is a seamless experience, thanks to its convertible design and included stabilizing feet. Once powered on, the double-conversion topology goes to work, constantly regenerating the incoming AC power into clean DC power, and then back into a perfect AC sine wave. This process completely isolates sensitive electronics from utility line noise, frequency variations, and voltage spikes. During a blackout, the transition to battery power is completely imperceptible to connected equipment because the inverter is already running off the internal DC bus. For facilities requiring extended backup windows, the ability to daisy-chain up to ten SRT96RMBP external battery packs provides peace of mind, scaling runtime from minutes to hours.
When compared to standard line-interactive UPS systems, the APC SRT3000XLTW offers superior protection. Line-interactive models must transfer from utility power to battery power when a brownout or blackout occurs, creating a brief 4-to-8 millisecond transfer window that can cause sensitive servers or medical equipment to reboot. The SRT3000XLTW's online double-conversion design eliminates this transfer gap entirely. Furthermore, while lower-tier UPS units output a simulated or stepped sine wave, this unit delivers a pure, continuous sine wave, which reduces heat generation and electrical stress in high-efficiency active PFC power supplies.
To help you optimize your power protection strategy, here are answers to frequently asked questions:
- Can I use this UPS with standard 120V wall outlets? No, this unit is designed for high-voltage environments, requiring a 208V or 240V input via a NEMA L6-20P plug, and outputs 208V/240V power.
- How do I mount this unit in a standard 19-inch server rack? The UPS can be rack-mounted using compatible rail kits (such as the SRTRK4 or SRTRK3, sold separately), occupying 2U of rack space when oriented horizontally.
- What happens if the internal inverter fails or is overloaded? The UPS features an automatic and manual internal bypass that seamlessly routes utility power directly to the connected loads without interruption.
- How many external battery packs can be added to extend runtime? You can connect up to 10 external battery packs (model SRT96RMBP) to significantly scale up the backup duration for long-term outages.
- Is the battery hot-swappable, and what is its expected lifespan? Yes, the internal lead-acid battery module is user-replaceable and hot-swappable, with an expected operational lifespan of 3 to 5 years under normal operating conditions.
