Product Highlights
Description
APC Smart-UPS SMT750CUS — 750VA Tower Line-Interactive UPS
The SMT750CUS delivers 750VA / 500W of clean pure sine wave power in a tower form factor designed for 120V environments. As part of APC's Smart-UPS line-interactive series, it provides Automatic Voltage Regulation to correct utility brownouts and surges without unnecessary battery cycling — the practical difference between a UPS that lasts five years and one that needs new batteries in two.
Why Line-Interactive UPS for This Load Range?
Line-interactive topology sits between basic standby UPS (no voltage regulation) and double-conversion on-line UPS (continuous inverter operation). For loads in the 750VA range serving servers, network equipment, and VoIP infrastructure, line-interactive provides the right balance of power quality, energy efficiency, and acquisition cost. Connected equipment sees clean pure sine wave output during voltage events, but the unit doesn't waste energy or battery life converting power continuously when utility power is acceptable.
Key Features
- Pure Sine Wave Output: The pure sine wave inverter matches the waveform of utility power, ensuring compatibility with active PFC server power supplies, medical-grade equipment, and other devices that reject approximated waveforms.
- Automatic Voltage Regulation (AVR): When utility voltage drifts outside acceptable thresholds, AVR corrects the output without engaging the battery, reducing battery cycling and extending replacement intervals — a practical TCO benefit over the life of the UPS.
- APC SmartConnect Cloud Port: Cloud-based remote management through the APC SmartConnect portal eliminates the need for VPN access to monitor individual UPS units across multiple sites.
- SmartSlot Expansion Bay: SmartSlot expansion allows post-purchase addition of network management, environmental sensors, or contact closure modules without replacing the UPS.
- LCD Diagnostic Display: LCD displays load percentage, estimated runtime, input and output voltages, and recent event history for at-the-rack diagnostics.
- User-Replaceable Battery: Field-replaceable battery cartridges allow internal IT teams to perform routine battery refreshes. Questyme keeps compatible replacement cartridges in inventory.
- PowerChute Compatibility: Graceful shutdown of physical servers, hypervisor hosts, and HCI clusters through PowerChute Business Edition or PowerChute Network Shutdown.
