Design and Build Quality

The SMT1000I features a compact, tower-style design with a black or charcoal finish, making it suitable for office or server room environments. Measuring 8.62 x 6.73 x 17.28 inches, it’s relatively small for a 1000VA UPS, allowing it to fit under a desk or in a network closet. The durable plastic enclosure is built to withstand typical use, and the front-mounted multifunction LCD provides clear status updates, including load, battery status, and input/output voltage.

While not rack-mountable, the tower design is stable and easy to position. The unit’s weight (18.86 kg) is due to the internal lead-acid battery, which is user-replaceable via the APC Replacement Battery Cartridge (RBC6). Users appreciate the straightforward design but note that the weight makes it less portable than smaller UPS models.

Performance

The APC Smart-UPS 1000VA delivers reliable performance for protecting critical electronics. Its line-interactive topology corrects minor voltage fluctuations (brownouts and overvoltages) without switching to battery power, thanks to the built-in Automatic Voltage Regulation (AVR). This feature boosts low input voltage by up to 30% and trims high voltage by up to 12%, extending battery life and ensuring stable power delivery.

The pure sine wave output is a key highlight, making the SMT1000I compatible with sensitive equipment like servers and networking devices that use active power factor correction (PFC) power supplies. Real-world tests indicate a runtime of about 6 minutes at full load (600W), with extended runtime for lower loads (e.g., 60W yields over 60 minutes). The UPS’s efficiency is impressive, with a patented Green Mode achieving over 97% efficiency by bypassing unused components during stable power conditions, reducing energy costs and heat output.

Data transfer and management are seamless via USB or serial connections, and the optional SmartSlot allows for network management with a Network Management Card (sold separately). The UPS supports PowerChute Business Edition, enabling remote monitoring, graceful shutdowns, and energy management for servers, virtual machines, and HCI clusters.

Security and Management Features

The SMT1000I is packed with features to enhance reliability and manageability:

  • Intuitive LCD Interface: Displays critical information like load, battery charge, and estimated runtime, with easy-to-use navigation keys for local configuration.
  • PowerChute Software: Facilitates automatic shutdown of connected systems during extended outages, preventing data loss.
  • SmartSlot Expandability: Supports optional cards for network management, dry contact I/O, or protocol translation.
  • Audible Alarms: Alerts for on-battery operation, low battery, or overload conditions, with configurable delay settings.
  • Automatic Self-Test: Periodically checks the battery to detect issues early, ensuring reliability.
  • Temperature-Compensated Charging: Adjusts charge voltage based on battery temperature, prolonging battery life.

These features make the SMT1000I a robust solution for IT professionals and network administrators needing dependable power protection.

Compatibility

The SMT1000I is designed for broad compatibility. It works out of the box with Windows, macOS (with appropriate software), and other operating systems via USB or serial connections. The 8x IEC C13 outlets and 2x IEC jumpers accommodate a variety of devices, including servers, routers, switches, and desktops. The UPS is also compatible with EcoStruxure IT and third-party management platforms, making it versatile for enterprise environments.

For Mac users, the PowerChute software ensures seamless integration, and the UPS supports graceful shutdowns for virtualized and hyperconverged infrastructure. The optional Network Management Card enables remote monitoring over Ethernet, ideal for distributed IT setups.

Reliability and Durability

APC is a trusted name in power protection, and the SMT1000I upholds this reputation. The sealed lead-acid battery (RBC6) is hot-swappable and user-replaceable, reducing downtime. The UPS has a 1-year warranty for the unit with APC’s customer support available for assistance. User feedback highlights the unit’s reliability, with many reporting years of trouble-free operation when properly maintained.

However, some users note that the battery typically lasts 3-5 years, after which replacement is necessary. The UPS’s self-test and disconnected battery notifications help prevent unexpected failures. The unit’s surge protection (455-459J) and noise filtering safeguard connected devices from lightning strikes, surges, and electrical noise.
