Rated apparent output The manufacturer-rated apparent-power output limit of the exact UPS revision. Check this alongside its separate continuous watt limit. A larger VA rating does not by itself establish longer runtime.	1500 VAApparent-power rating, separate from the 900 W real-power limit.

Topology and voltage regulation The documented UPS topology and automatic voltage regulation arrangement. Retain the maker’s qualifications. Line-interactive operation and AVR do not establish zero transfer time or online double-conversion operation.	Line interactive; boost and trim AVRThe BR1500MS2 manual table specifies +11.5% boost below its input limit and -11.5% trim above it. This is not an online double-conversion UPS.

Output waveform on battery The waveform explicitly documented while the UPS runs from its battery. Keep sine-wave and simulated or stepped output distinct. Do not infer a waveform from a product family or an omitted specification.	Sine waveThe BR1500MS2 table specifies sine-wave battery output. Other models in this shared manual use different waveforms and must not be substituted.

Battery-backed AC outlets The number of AC receptacles supplied by the battery during an outage. Count the outlets needed by all backed equipment and check plug spacing. Surge-only outlets do not keep equipment powered.	6 outletsSix NEMA 5-15R AC outlets provide battery backup and surge protection.

Surge-only AC outlets The number of AC receptacles with surge protection but no battery backup. A known zero means no surge-only outlets. An unknown count is not zero, and these outlets cannot power outage-critical network equipment.	4 outletsFour NEMA 5-15R AC outlets provide surge protection only.

Total outlet count alone does not establish that every power adapter will fit.	NEMA 5-15P input; ten NEMA 5-15R AC outletsUS input cord is specified as 6 ft.

Qualified transfer time The source’s transfer-time claim with its typical, maximum or other qualification retained. Do not turn a typical figure into a guaranteed maximum. Device power-supply tolerance and the complete installation still need verification.	Sources disagree The sources give different answers, so we have not chosen one as fact. Read the attached notes and confirm the current specification before relying on it. The current US page states 8 ms typical / 10 ms maximum; the April 2026 BR1500MS2 manual table states 8 ms maximum. Numeric load and transfer-test conditions are not supplied. Do not choose one limit as resolved.

USB power monitoring Whether the UPS documents a USB data interface for monitoring power status. This is not a NAS compatibility verdict. USB charging ports do not establish monitoring, and successful detection alone does not prove shutdown or restart.	YesThe manual directs the supplied USB communication cable from the rear Data Port to the protected device. This is a data connection, separate from front charging; exact NAS/OS support and shutdown/restart behavior are not established.

USB monitoring cable included Whether the exact package documents the USB data cable needed for its monitoring connection. Check both cable ends and the receiving device. Included charging cables and optional management cables do not establish this field.	YesInventory and connection instructions confirm the supplied USB communication cable. An optional serial cable is not supplied. The rear Data Port connection must not be described as a standard USB Type-B socket without exact connector evidence.

Network management scope Documented network management hardware and protocol support, distinguishing included, optional and unavailable equipment. An RJ45 surge-protection jack is not a network management interface. NAS network-server relay is a separate software configuration, not a built-in UPS network card.	Not verified We have not verified this value. It is not a confirmed no or zero. Check the original source or ask the manufacturer if it affects your choice. The reviewed sources establish USB and optional serial communication, not an IP management interface or network-card entitlement. Ethernet IN/OUT sockets provide surge protection and are not network management.

Replacement battery and revision The documented replacement battery part, including any model revision or serial-prefix conditions. Check the delivered unit’s label before ordering. A merchant model name alone cannot select a battery when serial-dependent replacements exist.	APCRBC163Exact BR1500MS2 replacement cartridge in the current US page and April 2026 manual page 17.

Manufacturer runtime at 100 W A directly documented runtime estimate at a total 100 W load for this revision. Read the runtime conditions and evidence note.

Manufacturer runtime at 200 W A directly documented runtime estimate at a total 200 W load for this revision. Compare only the same load and compatible stated conditions. Reserve shutdown time; actual load, charge, age and environment can shorten operation.	36 minVisible manufacturer runtime calculator set to exactly 200 W.

Runtime estimate conditions The stated battery, load and environmental conditions behind the documented runtime estimates, with omissions retained. Manufacturer estimates are separate from CompareFoundry measurements. A new, fully charged battery estimate is not an installed-system guarantee.	Manufacturer runtime-calculator estimate at the stated absolute load. Battery age, charge state, ambient temperature and load power factor are not stated; real runtime varies.The reviewed calculator did not state the same new-battery/full-charge conditions used on the CyberPower pages.

Unit weight Published unit weight for the reviewed configuration, with battery scope qualified by the source. Keep shipping weight separate. Plan a stable location with the manufacturer’s required ventilation and access.	12.5 kgManufacturer product weight, also stated as 27.6 lb. This is not shipping weight.

Body dimensions Published body dimensions with the source’s axis order and units. Body measurements are not installation clearance. Allow for plugs, cable bends, ventilation and battery replacement access.	Sources disagree The sources give different answers, so we have not chosen one as fact. Read the attached notes and confirm the current specification before relying on it. The current page labels H 260 x W 100 x D 368 mm. Manual page 16 lists 11.9 x 4.4 x 15.0 in with 368 x 100 x 260 mm and no axis labels in that row; the two unit representations are internally inconsistent. Resolved dimensions remain unknown; no installation-fit claim. Sources · 2026-10-03 APC by Schneider Electric: BR1500MS2 US purchase page, specifications and runtime calculatorChecked 2026-10-03.

Questions to check before buying	Transfer time is conflicting: current US page 8 ms typical / 10 ms maximum versus April 2026 manual 8 ms maximum. No resolved transfer limit is asserted. Body dimensions are conflicting, including internally inconsistent inch/mm values in the current linked manual. No body-size or installation-fit assertion is resolved. The manufacturer runtime calculator supplies the exact 100 W and 200 W estimates, but does not state battery age, charge state, numeric ambient temperature or load power factor. These conditions are not assumed to match CyberPower's. No physical USB shutdown, power-outage or restoration test was performed. A supplied data cable does not establish exact NAS/firmware compatibility. Network management is unknown from the reviewed sources. Ethernet surge-protection connectors must not be treated as a network management interface.
