APC SMX120BP Smart-UPS X 120V External Battery Pack
Overview
The APC SMX120BP is a dedicated external battery pack engineered for the APC Smart-UPS X series of rack/tower convertible uninterruptible power supplies. Rather than a standalone UPS, the SMX120BP extends the runtime of a compatible Smart-UPS X unit by adding a 120V, 1200VAh bank of maintenance-free, hot-swappable sealed lead-acid batteries, letting facility and IT teams tailor backup runtime to the load they need to protect during a mains outage.
Seven Star LLC, an experienced supply partner for APC by Schneider Electric power protection products in Oman and the GCC, supplies genuine APC SMX120BP battery packs to data centers, industrial control rooms, and telecommunications facilities. Each unit is sourced through verified Schneider Electric distribution channels, ensuring correct voltage matching and full compatibility with the customer’s existing Smart-UPS X installation.
Measurement and Operating Principle
The APC SMX120BP does not condition or convert power itself; instead, it is wired in parallel to the host Smart-UPS X unit’s internal battery bus, and the UPS automatically recognizes the added external pack and adjusts its runtime calculation accordingly. When utility power fails, the Smart-UPS X draws current from both its internal batteries and any connected SMX120BP packs simultaneously, extending the time the protected load can run on battery before a graceful shutdown or generator transfer is required.
Up to ten SMX120BP battery packs can be daisy-chained to a single Smart-UPS X unit for extended-run applications, and the system’s temperature-compensated charging circuit manages all connected packs together to maximize battery life and prevent overcharging in warm equipment room environments, a common concern in Gulf-region data centers and control rooms.
Engineering Design
The APC SMX120BP is housed in a 4U rack-mount enclosure that is also tower-convertible, matching the mechanical form factor of the Smart-UPS X unit it supports so the two can be stacked or mounted side by side in the same rack or equipment room. The internal batteries are hot-swappable, meaning a technician can replace an aging battery module without powering down the UPS or interrupting protection to the connected load, an important feature for facilities that cannot tolerate planned protection gaps.
Battery life for the SMX120BP is rated at three to five years under normal operating conditions, and the pack’s sealed, spill-proof construction makes it safe to install in enclosed equipment rooms without special ventilation for battery off-gassing. The rack/tower convertible chassis lets Seven Star LLC customers standardize a single SMX120BP part number across both rack-mounted and free-standing tower deployments.

Industrial Applications
The APC SMX120BP is deployed wherever a Smart-UPS X installation needs more backup runtime than its internal batteries alone can provide, including data centers, network operations centers, and industrial control rooms running SCADA and DCS workstations that must stay powered through extended utility outages. It is also common in telecommunications shelters and process plant instrumentation rooms where a graceful, delay-tolerant shutdown sequence depends on extended UPS runtime.
Seven Star LLC supports Smart-UPS X extended-runtime projects across Oman’s data center, oil and gas, and telecommunications sectors, supplying the SMX120BP to facilities in Muscat, Sohar, and Salalah. As a trusted supplier of APC by Schneider Electric products, Seven Star LLC helps GCC customers size the correct number of battery packs for their required runtime and load profile before ordering.

Compatibility and Ordering Notes
Because the APC SMX120BP is voltage-matched specifically to the Smart-UPS X series, Seven Star LLC verifies the customer’s existing UPS model before dispatch to guarantee correct fit and full runtime extension. Facilities standardizing on Smart-UPS X across multiple sites in Oman often keep a small stock of SMX120BP packs on hand so that runtime can be extended on short notice as load requirements grow, and Seven Star LLC supplies the packs on request with lead time confirmed at quotation.
Deployment Notes for the Smart-UPS X Fleet
Seven Star LLC has observed that Omani data center operators typically add a first SMX120BP battery pack at commissioning and reserve rack space for a second pack as compute density grows, since retrofitting rack space later is often the harder constraint compared to the battery pack itself. Because the pack is hot-swappable, technicians can also rotate aging battery modules out of service during scheduled maintenance windows without ever dropping protection on the load, which matters for facilities running 24/7 SCADA, telecom switching, or financial transaction workloads where even a brief unprotected window is unacceptable.
For customers evaluating total cost of ownership, Seven Star LLC can provide runtime tables showing exactly how many minutes of additional backup each SMX120BP pack contributes at a given load percentage, helping facility engineers make a data-driven decision between adding battery packs versus upsizing to a larger Smart-UPS X model.

Where APC UPS systems are used
In industrial plants across the GCC, APC UPS units back up DCS and PLC cabinets, operator stations, SCADA servers, telecom racks, fire and gas panels and analyzer shelters. Online double-conversion models are normally chosen for control systems because the load is always fed through the inverter. Line-interactive units suit office IT and less critical loads.Ordering APC UPS units and parts: what we need
Send the full SKU, for example SRT3000XLI, and not only the VA rating. The letters carry meaning: an I in the suffix marks a 230 V international model, XL an extended-run version that accepts external battery packs, and RM a rack-mount form. For a new requirement, give load in watts, input and output voltage, required runtime, tower or rack format, and the plug or hardwire arrangement. For batteries, send the UPS SKU and serial number so the correct replacement battery cartridge can be found in APC documentation.Browse APC products by category: UPS and Batteries.
