APC SMTL1500RM3UCNC 1500 VA Lithium‑Ion UPS 120 V

Overview :

The APC SMTL1500RM3UCNC is a line‑interactive uninterruptible power supply (UPS) designed to deliver conditioned AC power and short‑duration backup for critical IT equipment in 120 V single‑phase power environments. It is typically deployed by network engineers, infrastructure technicians, and data‑centre operators to protect servers, network switches, storage devices, VoIP/UC systems, and other sensitive electronics from brownouts, surges, and outages while enabling orderly shutdowns or transitions to standby power. ([turn0search0], [turn0search1])

This UPS is rated at 1500 VA / 1350 W and uses a line‑interactive topology with Automatic Voltage Regulation (AVR) to stabilise utility voltage without engaging the battery whenever possible. The lithium‑ion battery chemistry offers extended service life compared to traditional lead‑acid designs, reducing maintenance and replacement cycles over its operational lifetime.

Mechanically, it installs into standard 19″ racks at 3U height with included mounting rails in a short‑depth rackmount form factor that optimises space in IDF/MDF cabinets and edge enclosures. The unit also supports shallow cabinets and cable‑dense environments without compromising rack usability. ([turn0search1], [turn0search12])

Management and monitoring include built‑in SmartConnect Ethernet, Network Management Card (APC NMC) functionality, USB, and serial interfaces, enabling remote UPS status, alerts, and integration into centralised platforms such as APC EcoStruxure IT or third‑party SNMP systems. A multifunction LCD console reports real‑time load, voltage, and battery status locally. ([turn0search3], [turn0search10])

Internal runtime at full load is ~3 minutes and at half load ~8–9 minutes, sufficient for critical system shutdowns or generator handoff. Typical battery recharge time is ~3 hours, and the lithium‑ion design delivers fast recovery with long lifecycle performance. ([turn0search5], [turn0search1])

This UPS is not suited for 208 V/230 V mains distribution without the correct regional variant nor for extended continuous runtime without external expansion solutions. It is optimised for short outage bridging and voltage regulation in medium rack deployments.
