APC by Schneider Electric SMT1000C Line-Interactive 1000VA Tower UPS

Overview

The APC by Schneider Electric SMT1000C is a 1000VA / 700W line-interactive uninterruptible power supply built for small server rooms, network closets, and commercial surveillance infrastructure where clean, conditioned power is non-negotiable. It delivers a true sine wave output, automatic voltage regulation across a wide 75–154V input window, and a SmartConnect management port — all in a compact tower form factor that fits on a shelf or beside a rack. If you're protecting NVRs, edge switches, access control panels, or workstations that can't tolerate power anomalies, the SMT1000C is engineered to absorb those events without a battery switchover.

For teams speccing UPS and power protection solutions alongside network video recorders and IP security systems, this unit sits in the APC Smart-UPS line — a series long established in commercial IT and physical security deployments.

Key Features

• Line-Interactive Topology with True Sine Wave Output: Unlike simulated (stepped) sine wave units, the SMT1000C produces a pure sine wave on battery — critical for active PFC power supplies found in modern servers, NVRs, and enterprise networking gear. A simulated wave can cause equipment to fault or run hot; this unit eliminates that risk entirely.
• 1000VA / 700W Capacity: At 700W real power, this UPS can carry a modest NVR plus two or three PoE switches, or a small server and associated networking equipment. Size your load to 80% of rated capacity (560W) for headroom and optimal battery life — don't load it to the ceiling.
• Automatic Voltage Regulation (AVR), 75–154V Input Window: The SMT1000C corrects under-voltage down to 75V and over-voltage up to 154V without switching to battery. In facilities with notoriously dirty utility power — older buildings, manufacturing adjacent, or sites with heavy HVAC — this wide window means far fewer battery cycles and significantly longer battery lifespan.
• 680 Joule Surge Energy Rating: The integrated surge suppressor handles 680J of transient energy. That's adequate for most in-building events; for direct-exposure or outdoor-adjacent runs, supplement with a dedicated panel-level surge device.
• 10 ms Transfer Time: When utility power falls outside the operating window and the unit must switch to battery, it does so in 10 milliseconds — well within the hold-up time of virtually all double-conversion power supplies in commercial equipment.
• EMI/RFI Noise Filtering: Beyond surge and sag correction, the SMT1000C filters electromagnetic and radio-frequency interference on the line. In environments with motors, variable-frequency drives, or dense RF (warehouses, manufacturing floors), this matters for keeping sensitive security electronics stable.
• SmartConnect Port (Web-Based Management): The SmartConnect cloud management port enables remote monitoring without requiring a dedicated local network management card. For smaller deployments where a full NMC is cost-prohibitive, this gives you visibility into runtime estimates, load percentage, battery health, and event logs from a browser.
• Audible Alarm System: Three distinct alarm modes — on-battery, low battery, and overload — give on-site staff immediate audio indication of power events. The 41 dB noise floor means alarms are audible without being disruptive in office-adjacent deployments.
• Short Circuit Protection: Built-in short circuit protection prevents a downstream fault from propagating upstream or damaging the UPS itself — a baseline requirement for any always-on security infrastructure.
• 8x NEMA 5-15R Outlets, 120V: Eight protected outlets give you enough ports to power an NVR, a PoE switch, a workstation, and a modem/router simultaneously. All outlets are battery-backed and surge-protected — there are no
