APC Smart-ups 1000VA LCD 100V - SMT1000J

APC by Schneider Electric SMT1000J Line-Interactive 1000VA Tower UPS

Overview

The APC by Schneider Electric SMT1000J is a 1000VA / 670W line-interactive uninterruptible power supply purpose-built for the Japanese 100V grid. Delivering true sine wave output, an front-panel LCD, and a SmartSlot expansion bay, the SMT1000J fits installations where clean, managed power backup is non-negotiable — think security head-end closets, small server rooms, POS clusters, and access control panels where a sudden outage means more than a reboot. The unit draws from a 100V AC input with an 80–123V automatic voltage regulation window (adjustable down to 70V) before the battery engages, which means most brownouts and sags are absorbed silently without a battery discharge cycle.

Key Features

• 1000VA / 670W True Sine Wave Output: Pure sine wave at AC 100V ±5% is required for active-PFC power supplies common in modern servers, NVRs, and network switches. A stepped approximation or simulated sine wave can cause those PSUs to run hot, trip protection, or fail outright. This unit eliminates that risk.
• 8 x NEMA 5-15 Protected Outlets: Eight output receptacles handle a full head-end build — NVR, PoE switch, managed switch, access controller, and supporting gear — without a daisy-chained power strip breaking the protection chain.
• Wide Input Voltage Range (80–123V, adjustable to 70V): Line-interactive topology with this voltage window means the battery stays out of the discharge cycle during routine utility sags. Fewer battery cycles directly extends battery service life and reduces replacement costs over a 3–5 year deployment horizon.
• 459-Joule Surge Energy Rating: Absorbs transient spikes before they reach connected equipment. Relevant in industrial buildings and older facilities where the grid is noisy — common in warehouse and manufacturing security deployments.
• Front-Panel LCD with Audible Alarm: Local status visibility without launching management software. Technicians can read load percentage, battery charge, and input voltage at a glance during commissioning or a service call. The 45 dBA audible alarm is noticeable in a server room without being disruptive to adjacent office space.
• SmartSlot Expansion Bay: One free SmartSlot accepts optional APC network management cards, enabling SNMP/web-based remote monitoring — a practical upgrade path if the site later needs centralized UPS status in a BMS or NMS without replacing the unit.
• USB Remote Management Interface: USB connectivity supports direct connection to a host system running PowerChute or compatible shutdown software for graceful OS shutdown during extended outages — prevents filesystem corruption on NVRs and servers when runtime is exhausted.
• 4-Hour Recharge Time: A depleted battery returns to full capacity in approximately four hours, keeping the protection gap short after a significant outage event.
• Operating Range 32°F–104°F (0–40°C), 0–95% RH: Covers standard indoor equipment room and server closet environments without derating — confirm ambient temperatures in non-climate-controlled utility rooms before specifying.

Integration and Compatibility

The SMT1000J is designed for the Japanese 100V / 50–60Hz grid. Input connectors are NEMA 5-15, and all eight output receptacles share the same format — confirm that all connected devices use compatible plugs for the target installation. The SmartSlot bay accepts the full range of APC optional network management and relay cards, enabling integration with building management systems, third-party NMS platforms, and remote monitoring workflows without replacing the base unit. The USB interface is compatible with APC PowerChute software for graceful server and NVR shutdown management.

Frequently Asked Questions

Q: What is the output waveform of the SMT1000J?

A: The SMT1000J delivers a pure sine wave output at AC 100V ±5%. This is required for equipment with active-PFC power supplies, which are standard in modern servers, NVRs, and network switches.

Q: How many outlets does the SMT1000J provide?

A: It provides 8 x NEMA 5-15 output receptacles, all battery-backed and surge-protected.

Q: What is the battery recharge time after a full discharge?

A: The battery recharges to full capacity in approximately 4 hours under normal conditions.

Q: Can the SMT1000J be monitored remotely over the network?

A: Not out of the box, but the single free SmartSlot expansion bay accepts optional APC network management cards for SNMP or web-based remote monitoring. The USB interface supports local PowerChute software integration for graceful shutdown.

Q: What input voltage range does the SMT1000J support?

A: It accepts AC 80–123V (adjustable to 70–125V) before switching to battery, making it well-suited for installations with variable utility power quality.

Q: What is the warranty on the SMT1000J?

A: APC provides a limited warranty of 2 years on the SMT1000J.

James Everett

The SMT1000J's 80–123V input regulation window is the spec I look at first on any Japan-market security head-end build. Line-interactive topology at that range means the battery stays idle through the routine brownouts common in older commercial buildings — and a battery that doesn't cycle unnecessarily will last significantly longer before needing replacement. For a 24/7 NVR environment, that matters.

Technical Highlights:

• Pure Sine Wave at 670W/1000VA: Active-PFC PSUs in modern NVRs and switches require sine wave output. Simulated or stepped waveforms cause thermal stress and can void equipment warranties — this unit eliminates that concern entirely.
• 459-Joule Surge Rating: Meaningful transient absorption for industrial and mixed-use facilities. Not rated for direct lightning strike paths, but sufficient for the switching noise and grid spikes typical in warehouse and light-industrial security installs.
• SmartSlot Expansion: The free slot means you can add a network management card post-deployment without swapping hardware — useful when a site's BMS or NMS scope expands after initial commissioning.

Deployment Considerations:

• This unit is localized for Japan's 100V grid and uses NEMA 5-15 connectors throughout. Confirm all connected devices share that plug format — especially imported security hardware that may ship with IEC C13 or C19 leads requiring an adapter.
• At 50.2 lbs, this is a tower unit that needs a dedicated shelf or floor position in the rack room. It is not rack-mountable in this configuration without an optional conversion kit — verify that before quoting into a rack-only install.

Best-fit scenario: a Japanese-market physical security head-end — NVR, managed PoE switch, access controller, and intercom gateway — where the facility has documented brownout history and the customer needs both local LCD visibility and a clear upgrade path to networked UPS monitoring without replacing the unit.
