Description
APC Smart-UPS X SMX48RMBP2U — 864VA Rack/Tower Convertible with Extended Runtime Architecture
The SMX48RMBP2U is a 864VA / 604W line-interactive UPS with a defining capability: support for up to 10 external battery packs. Where most UPS units lock you into the runtime they ship with, the Smart-UPS X (SMX) platform separates runtime from the base unit — letting you size the UPS for your load today and add runtime tomorrow as requirements evolve.
The Extended Runtime Architecture
Standard internal battery runtime sits in the minutes range under typical load. For data centers with reliable generator backup and 30-second transfer time, that is enough. For sites without generators, or with longer transfer windows, internal-only runtime is the wrong question. The SMX architecture solves this by allowing post-purchase runtime scaling — add packs as your runtime target grows without replacing the UPS itself.
Key Features
- External Battery Pack Support: Up to 10 SMX battery packs in series — runtime scales linearly with pack count.
- Rack/Tower Convertible: 2U Rack/Tower Convertible chassis fits standard 19-inch racks or deploys as a tower without rail kit modification.
- Pure Sine Wave Output: Pure sine wave output reproduces the smooth waveform of utility power, which sensitive electronics — active power-factor-corrected (PFC) server power supplies in particular — require to operate without errors or premature failure.
- Automatic Voltage Regulation: Automatic Voltage Regulation corrects undervoltage (brownouts) and overvoltage events without transferring to battery, conserving battery life for true outages and extending overall service life of the unit.
- SmartSlot Expansion: A SmartSlot accessory bay accepts optional Network Management Cards (AP9641, AP9643), environmental sensors, and dry-contact relay modules — useful for facilities that require SNMP integration, building management system tie-in, or PowerChute Network Shutdown of virtualized workloads.
- PowerChute Network Shutdown: Graceful shutdown coordination for physical servers, hypervisors (VMware, Hyper-V, KVM), and HCI clusters.

Ideal Applications and Industries
- Enterprise IT and Virtualization Hosts: Coordinates graceful shutdown of physical and virtual servers through PowerChute Network Shutdown when extended outages exceed runtime.
- Healthcare Diagnostic Equipment: Reliable backup power for imaging workstations, telemetry hubs, and lab analyzers where data integrity depends on clean shutdowns.
- Federal, State, and Local Government: Meets specification requirements for U.S.-aligned procurement programs; TAA-compliant variants available where required.
- Manufacturing and Industrial Controls: Powers PLCs, HMIs, and supervisory control workstations that cannot tolerate the brief voltage dips common to industrial environments.
- Retail Point-of-Sale and Hospitality: Keeps POS terminals, payment processors, and front-of-house systems online during transient power disturbances.
