In today’s tech-driven landscape, where servers, networking equipment, and critical systems underpin businesses and personal projects alike, power reliability is paramount. A sudden outage or surge can spell disaster—lost data, damaged hardware, or costly downtime. The APC Smart-UPS 5000VA Line Interactive Rackmount UPS (SUA5000RMI5U) from Schneider Electric’s APC brand rises to the occasion, delivering robust power backup and protection in a sleek, rack-optimized package. In this blog, we’ll explore its standout features, benefits, and why it’s a top pick for anyone needing dependable power in a rackmount setup.


What is the APC Smart-UPS 5000VA (SUA5000RMI5U)?

The APC Smart-UPS 5000VA (SUA5000RMI5U) is a line-interactive UPS designed to provide 5000VA (4000 watts) of power, tailored for 230V environments like those in Europe, Asia, and Africa. Housed in a 5U rackmount/tower convertible design, it’s built for data centers, server rooms, and IT closets where space efficiency and scalability matter. Part of APC’s award-winning Smart-UPS family, this model combines intelligent power management with a high-capacity output, making it ideal for protecting servers, networking gear, and other mission-critical devices.

Though an older model in the Smart-UPS lineup, the SUA5000RMI5U remains a favorite for its proven performance, straightforward operation, and cost-effectiveness—perfect for those who need serious power without the complexity of newer, feature-heavy units.


Key Features of the APC Smart-UPS 5000VA (SUA5000RMI5U)

  1. Line-Interactive Technology
    The SUA5000RMI5U uses line-interactive topology to regulate voltage fluctuations without taxing the battery. It corrects sags and surges in real time, ensuring stable power and preserving battery life for true emergencies.
  2. 5000VA/4000W Capacity
    With a hefty 5000VA rating and 4000 watts of output, this UPS can support substantial loads—think multiple servers, blade systems, or high-power networking equipment—keeping them online during outages.
  3. Rackmount/Tower Versatility
    At 5U, it fits seamlessly into standard 19-inch racks, but its convertible design also allows standalone tower use. Rack-mounting hardware and support rails are included for easy installation.
  4. Multiple Output Connections
    It offers 8x IEC C13 outlets, 2x IEC C19 outlets, and 4x IEC jumpers, all with battery backup. This variety accommodates a wide range of devices, from standard IT gear to high-draw equipment.
  5. Pure Sine Wave Output
    When on battery, the UPS delivers a pure sine wave, mimicking utility power. This is critical for sensitive electronics and power-factor-corrected (PFC) power supplies that demand clean energy.
  6. Serial and SmartSlot Connectivity
    A DB-9 RS-232 serial port enables integration with APC’s PowerChute software for monitoring and safe shutdowns. The SmartSlot allows optional management cards (e.g., network or environmental monitoring) to enhance functionality.
  7. Automatic Voltage Regulation (AVR)
    AVR adjusts incoming voltage—boosting low inputs by up to 30% and trimming high inputs by up to 12%—without relying on the battery, protecting equipment and extending runtime.
  8. LED Indicators and Audible Alarms
    Simple LEDs show power status, battery charge, and overload conditions, while audible alerts warn of power events, ensuring you’re always informed.
  9. Hot-Swappable Batteries
    Replace the battery (typically an RBC43) without powering down, minimizing downtime and maintaining protection during maintenance.
  10. Cold-Start Capability
    Power up connected devices even without utility power, making it handy for testing or emergency startups.
