APC by Schneider Electric SMT2200US Line-Interactive Tower UPS
Overview
The SMT2200US is a 2200VA line-interactive uninterruptible power supply in a tower form factor — the kind of unit that sits at the core of a server room, NVR rack, or access control head-end and keeps everything running when utility power gets unstable or drops entirely. At 2200VA and 120V output, it has enough capacity to carry a multi-camera NVR, managed PoE switch, and associated network gear through a typical outage without shedding load. Ten outlets — eight NEMA 5-15R and two NEMA 5-20 — give you enough circuits to distribute power across the devices that actually matter, rather than daisy-chaining strips off a single receptacle.
Line-interactive topology is the right call for most commercial security and IT deployments: it conditions power continuously (correcting sags and surges through the inverter without switching to battery) while reserving true battery backup for hard failures. That means your connected equipment isn't constantly toggling battery cycles on minor grid fluctuations, which extends both battery life and runtime longevity on connected devices.
The internal lead-acid battery is a sealed, maintenance-free design. Tower orientation (zero rack units) means the SMT2200US installs on a shelf or floor beside equipment rather than consuming rack space — the right fit when your rack is already dense with switches, NVRs, and patch panels, or when the head-end is in a closet without a full equipment rack. The 6-foot power cord gives you reasonable reach to a wall receptacle or PDU without extension cables, and the black enclosure blends into standard equipment room environments.
Key Features
- 2200VA / 120V Capacity: Sized to carry multiple concurrent loads — a fully loaded NVR, PoE switch, and networking stack can typically run together without pushing the unit past its rated output. Size your load to 70–80% of VA capacity for safe continuous operation.
- 10 Protected Outlets (8x NEMA 5-15R + 2x NEMA 5-20): The two NEMA 5-20 receptacles handle devices that draw more sustained current (servers, larger NVRs, workstations) without requiring an adapter, while the eight 5-15R ports cover standard security and networking gear. All ten carry battery backup and surge protection.
- Line-Interactive Topology: Voltage regulation runs continuously through the inverter, smoothing sags and surges before they reach connected equipment. This matters in commercial buildings where HVAC cycling and elevator motors regularly pull voltage down — devices stay stable without burning battery cycles on minor fluctuations.
- Lead-Acid Battery Backup: Sealed lead-acid chemistry is proven, field-replaceable, and widely available. When the battery reaches end-of-life, replacement is a standard maintenance task — no proprietary chemistry, no special ordering lead times.
- Tower Form Factor (0U Rack): Sits on a shelf, equipment table, or floor without consuming any rack space. Ideal for installations where rack real estate is fully committed or where there is no rack at all — a wiring closet shelf, a pedestal, or a dedicated equipment corner.
- 6-Foot Power Cord: Long enough to reach a wall outlet or PDU in most closet or equipment room layouts without requiring extension hardware, which matters for UPS installations where cord management affects airflow and inspection access.
Integration and Compatibility
The SMT2200US is well-suited as the primary power protection layer for security head-ends: NVRs, managed PoE switches, access control panels, video management servers, and intercommunication equipment all fall within typical load profiles for a 2200VA unit. The NEMA 5-15R and 5-20R outlet mix covers the full range of standard North American equipment without adapters. Tower orientation makes it a natural fit for non-rack installations — wiring closets, server shelves, and equipment pedestals common in mid-market commercial deployments.
For deeper integration, the APC by Schneider Electric Smart-UPS line supports USB and serial management interfaces on most configurations, enabling runtime monitoring, load management, and automated graceful shutdown through compatible software — verify specific interface availability against confirmed SMT2200US documentation before specifying. If you are evaluating tower UPS units for a security or IT deployment, pair the SMT2200US with a UPS sizing and runtime guide to confirm load capacity before purchase. For rack-dense environments, consider rackmount UPS options that reclaim floor and shelf space while maintaining equivalent protection. Supplementing with a managed PoE switch on a protected outlet ensures cameras and access readers stay powered through the transition to battery.
Frequently Asked Questions
Q: What is the output voltage of the SMT2200US?
A: The SMT2200US outputs 120V AC, compatible with standard North American equipment.
Q: What outlets does the SMT2200US include?
A: It includes 10 total outlets: 8x NEMA 5-15R and 2x NEMA 5-20, all with battery backup and surge protection.
Q: Does the SMT2200US mount in a rack?
A: No — the SMT2200US is a tower form factor (0 rack units). It is designed to sit on a shelf, floor, or equipment table, not in a rack. If you need rack mounting, APC offers rack/tower convertible variants in the Smart-UPS line.
Q: What type of battery does the SMT2200US use?
A: It uses a sealed lead-acid battery. This chemistry is maintenance-free, field-replaceable, and widely sourced when end-of-life replacement is needed.
Q: What is the power cord length on the SMT2200US?
A: The SMT2200US ships with a 6-foot power cord, providing adequate reach for most closet or equipment room installations.
Q: Is the SMT2200US suitable for protecting a multi-camera NVR system?
A: Yes — 2200VA provides sufficient headroom for a fully loaded NVR, a managed PoE switch, and associated networking equipment in most mid-market security deployments. Calculate your actual load and target 70–80% of the UPS VA rating for reliable continuous operation.
The SMT2200US is the unit I reach for when a security integrator needs a non-rack UPS with enough outlet count to cover an entire head-end without compromise. Ten protected outlets — eight 5-15R and two 5-20 — means you can land the NVR, switch, access control panel, and a workstation on a single protected source instead of splitting across two smaller units or daisy-chaining strips, which is both a cleaner install and a more defensible power architecture.
Technical Highlights:
- 2200VA / 120V Line-Interactive: Continuous voltage conditioning handles the sags and surges from HVAC and elevator loads in commercial buildings — connected equipment stays stable without burning battery cycles on minor grid events.
- NEMA 5-15R + 5-20R Mix: Two 5-20 receptacles handle higher-draw devices (servers, larger NVRs) natively; the eight 5-15R cover everything else. No adapters, no capacity surprises at installation.
- Tower / 0U Form Factor: Zero rack units consumed — installs on a shelf or floor in a wiring closet where there is no rack, or alongside a full rack without taking a single rack space.
Deployment Considerations:
- Target 70–80% load factor against the 2200VA rating when summing NVR, switch, and server loads — headroom keeps the unit out of thermal stress during sustained operation and gives runtime margin on battery.
- The 6-foot cord is adequate for most closet layouts, but plan your outlet location before finalizing shelf placement — extending a UPS power cord with a standard extension is not recommended and degrades protection.
The SMT2200US fits best in mid-market commercial security head-ends — a 16–32 channel NVR deployment, a multi-door access control panel, and the associated network stack — where tower placement is practical and ten individually protected outlets eliminate the strip-daisy-chain shortcuts that create single points of failure.
