APC by Schneider Electric BN1100M2-CA Back-UPS PRO 1100VA Line-Interactive UPS
Overview
The APC Back-UPS PRO BN1100M2-CA is a 1100VA / 600W line-interactive uninterruptible power supply built for small server rooms, network closets, security head-end racks, and workstation deployments where a brief power interruption can mean lost recordings, dropped connections, or corrupted data. The BN1100M2-CA combines automatic voltage regulation (AVR), a 1080-joule surge rating, and 10 NEMA 5-15R outlets in a compact desktop/tower form factor — giving you both runtime and protection in a single unit without the complexity of a rack-mount system.
Line-interactive topology is the right call for most commercial security and IT edge deployments: the inverter actively conditions voltage during brownouts and overvoltages (88–139V input range) so your connected equipment runs on stable 120V output without switching to battery every time the utility fluctuates. That extends battery life significantly compared to standby-only designs and reduces stress on sensitive electronics like NVRs, PoE switches, and workstations.
Key Features
- 1100VA / 600W Output Capacity: At 600W true output power, the BN1100M2-CA can simultaneously support a mid-range NVR, a PoE switch, and a workstation monitor — covering the core of a small surveillance head-end without overloading the unit. Size your connected load to 80% of rated wattage (≤480W) for optimal runtime and battery longevity.
- Line-Interactive AVR (88–139V Input Range): The automatic voltage regulator corrects under-voltage (brownouts) and over-voltage conditions without touching the battery. In areas with unstable utility power — common in commercial construction zones, older buildings, and distributed branch offices — this keeps NVRs and managed switches from rebooting unexpectedly during voltage sags.
- 1080-Joule Surge Energy Rating: Surge energy capacity measures how much transient energy the unit can absorb before clamping fails. At 1080J, this is well above entry-level power strips (typically 200–600J), providing meaningful protection for NVR storage arrays and network switches that are expensive to replace and difficult to restore after a surge event.
- 8ms Transfer Time to Battery: When utility power fails entirely, the BN1100M2-CA switches to battery in 8 milliseconds. Most ATX power supplies and NVR internal PSUs tolerate up to 20ms without a brownout reset — so 8ms keeps your recording equipment running through the transfer without a hiccup.
- 10 NEMA 5-15R Outlets: Ten outlets give you enough ports to cover the core head-end stack without a separate PDU. A typical deployment: NVR, PoE switch, workstation, monitor, and a spare for a router or secondary device — all on a single protected and surge-managed circuit.
- Built-In LCD Display: The LCD gives you at-a-glance status on load percentage, battery charge, input voltage, and estimated runtime without connecting to management software. In a wiring closet where you're doing a quick install check, that's faster than pulling up a laptop.
- 2 USB Charging Ports: Dedicated USB 2.0 charging ports let technicians and operators charge mobile devices without burning an AC outlet or adding an adapter. Useful in surveillance control rooms where tablets and handhelds are part of the daily workflow.
- 45 dB Noise Level: At 45 dB, the unit runs at roughly the noise level of a quiet office or library — acceptable for deployments in open office security desks or reception-area NVR closets where a loud UPS fan would be disruptive.
- 60 Hz / 120V Output: Fixed 120V/60Hz output is North America–standard, matching the BN1100M2-CA's CA (Canada) designation. Confirmed compatible with all standard NEMA 5-15P equipment across the security and IT peripherals stack.
Integration & Compatibility
The BN1100M2-CA's 10 NEMA 5-15R outlets accept standard three-prong North American plugs — compatible with virtually all NVRs, PoE switches, workstations, and monitors sold for the North American market. The USB interface supports APC's PowerChute software for graceful OS shutdown and power event logging on connected Windows and Linux hosts, which matters for network video recorders running Windows-based VMS platforms where an unclean shutdown can corrupt the recording database.
For security integrators building out UPS and power protection solutions for surveillance head-ends, the BN1100M2-CA pairs naturally with a managed PoE network switch on the protected outlet bank — keeping camera feeds alive during short outages while the NVR continues writing to disk. Consult your camera and system sizing guide to calculate runtime requirements based on your specific load before purchasing. For larger deployments with higher wattage demands, review the broader APC UPS lineup for higher-capacity models in the Back-UPS PRO family.
Frequently Asked Questions
Q: What is the maximum connected load for the BN1100M2-CA?
A: The BN1100M2-CA is rated at 600W output power. APC recommends keeping connected load at or below 80% of rated wattage — approximately 480W — for optimal battery runtime and longevity. Exceeding 600W will trigger the overload protection.
Q: Does the BN1100M2-CA protect against brownouts, or only full power failures?
A: Yes. The line-interactive topology includes automatic voltage regulation (AVR) that corrects input voltages between 88V and 139V without switching to battery. It only transfers to battery when input falls outside that range or drops entirely.
Q: What type of outlets does the BN1100M2-CA have, and how many are battery-backed vs. surge-only?
A: The unit provides 10 NEMA 5-15R outlets. The specific split between battery-backed and surge-only outlets is not detailed in the available evidence — consult the product packaging or APC documentation for the exact outlet bank configuration.
Q: What is the surge energy rating on the BN1100M2-CA?
A: The BN1100M2-CA carries a 1080-joule surge energy rating, which provides substantially more transient protection than a standard power strip and is appropriate for protecting NVRs, managed switches, and workstations.
Q: How loud is the BN1100M2-CA during normal operation?
A: Noise output is rated at 45 dB under normal operating conditions — roughly equivalent to a quiet office environment. On battery, fan noise will increase.
Q: Is the BN1100M2-CA compatible with APC PowerChute software?
A: The BN1100M2-CA includes a USB interface that supports APC PowerChute software for graceful shutdown and power event logging on connected hosts. This is the standard connectivity method for the Back-UPS PRO family; confirm PowerChute version compatibility with your OS before deployment.
The BN1100M2-CA hits a useful middle ground for security head-end power protection: 600W true output and line-interactive AVR at a desktop form factor, without the cost or complexity of a rack-mount unit. I spec this class of UPS when the deployment is a single-rack or under-desk NVR stack where you need brownout ride-through more than you need extended runtime — the 88–139V AVR window is wide enough to handle the voltage instability common in commercial renovations and older warehouse electrical.
Technical Highlights:
- Line-Interactive AVR (88–139V): Corrects under- and over-voltage without discharging the battery, which matters in buildings where voltage sags are frequent. Battery-only UPS units in the same price range will cycle the battery constantly in those environments, shortening its service life to under 2 years.
- 1080J Surge Rating: More than double the surge capacity of a typical retail power strip. For an NVR or managed PoE switch — equipment that's expensive and time-consuming to replace — this margin is worth having.
- 8ms Transfer Time: Fast enough that ATX-based NVR platforms and standard server PSUs won't register a brownout reset during the transfer to battery. That keeps recording continuity intact through a utility dropout.
Deployment Considerations:
- The 600W output ceiling means you need to add up your connected load carefully before install. An NVR with multiple spinning drives, a PoE switch with 8+ cameras, and a workstation can easily approach or exceed 480W (80% load target) — do the math before you rack and stack.
- The BN1100M2-CA carries a Canadian market designation (CA suffix). Confirm your jurisdiction's warranty and support terms apply before deploying in cross-border deployments.
Best fit: small-to-mid surveillance head-ends in branch offices, retail back rooms, or wiring closets where the total protected load stays under 480W and the priority is voltage conditioning plus short-outage ride-through — not multi-hour runtime for a large server stack.
