The APC Smart-UPS SMTL1500RMI3UC is a robust and efficient 1500VA / 1350W line-interactive Uninterruptible Power Supply designed specifically for small edge environments, network infrastructure, and IDF/MDF closets. Featuring a *lithium-ion* battery technology, this UPS reduces the frequency of battery replacements and extends overall service life compared to traditional lead-acid batteries.

Its short-depth 3U rackmount design provides compatibility with shallow racks and improves cable management, measuring approximately 438 mm (W) x 302 mm (D) x 131 mm (H) and weighing about 19.5 kg. The unit delivers a pure sine wave output on battery, along with Automatic Voltage Regulation (AVR) to stabilize input voltage fluctuations without draining the battery.

Connectivity and management are enhanced by a SmartConnect Ethernet port for cloud-based remote monitoring, firmware updates, and proactive alerts, alongside a SmartSlot for optional network management cards facilitating remote control and graceful shutdown via PowerChute software. The intuitive multi-function LCD status console combined with audible alarms and LED indicators offers real-time status and actionable notifications.

Battery management includes intelligent temperature-compensated charging, automatic self-tests, predictive replacement date notifications, and a rapid recharge time of approximately 3 hours. The system supports cold-start operation for temporary battery power when grid power is unavailable.

Additional features include six IEC 60320 C13 battery-backed outlets, an IEC C14 input, surge protection, an energy meter displaying kWh usage, a patented green operating mode for improved efficiency, and compatibility with third-party centralized management platforms such as EcoStruxure IT.

Environmental and safety compliance: operates in 0–40°C temperature range and 0–95% relative humidity (non-condensing), conforms to CE, RCM, IEC 62040 standards, and carries Schneider Electric’s Green Premium environmental credentials.

This UPS is an ideal choice to ensure reliable power protection, efficient management, and extended battery lifespan in critical IT and network edge applications.
