Description
APC Smart-UPS X SMX48RMBP2US — 864VA Rack/Tower Convertible with Extended Runtime Architecture
The SMX48RMBP2US 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: Delivers a clean pure sine wave to connected equipment. Active PFC power supplies common in modern servers and storage arrays will throw errors or shut down on the simulated/stepped-wave output produced by entry-level UPS units; pure sine eliminates that risk.
- Automatic Voltage Regulation: AVR uses a buck-and-boost transformer stage to bring out-of-range utility voltage back to nominal levels in real time. The UPS only transitions to battery for true outages, which significantly extends battery service life.
- SmartSlot Expansion: The SmartSlot bay accepts APC accessory cards including the AP9641 Network Management Card 3 for SNMP/web management, environmental monitoring modules, and dry-contact modules for building automation integration.
- PowerChute Network Shutdown: Graceful shutdown coordination for physical servers, hypervisors (VMware, Hyper-V, KVM), and HCI clusters.
