APC SMX3000RMLV2U 3000 VA Line‑Interactive UPS

Overview

The APC SMX3000RMLV2U is a line‑interactive uninterruptible power supply (UPS) designed to provide conditioned power and short‑duration backup for critical IT systems on a single‑phase 120 V distribution infrastructure. It is deployed by network/system engineers and data centre technicians to maintain uptime for servers, storage, network appliances, and communication equipment during utility power fluctuations or outages.

Rated at 3000 VA / 2700 W (nominal), this UPS uses automatic voltage regulation (AVR) and a pure sine‑wave output to support sensitive electronics without generator transfer delays. The unit features low‑voltage sensitivity settings and rapid transfer times (~2–4 ms) to cope with utility anomalies.

Architecturally, it is a 2U rackmount with tower conversion, providing flexibility for installation in 19″ server racks or as a standalone tower. Typical 120 V input/output aligns with North American power distribution standards, and the included rack mounting kit simplifies integration into IDF/MDF cabinets, edge compute closets, or small data room racks.

Electrical connectivity includes a NEMA L5‑30P input and a mix of NEMA 5‑15R, 5‑20R, and L5‑30R outlets for distributed loads. The UPS supports SmartSlot management cards, USB, and RS‑232 communications for remote monitoring, sequencing, and graceful shutdown via APC PowerChute or third‑party management platforms.

Typical runtime at full load is ~6 min and at half load ~18 min, sufficient to bridge short outages or to execute orderly shutdown procedures before extended power loss. External battery packs (e.g., SMX120RMBP2U) can be added to scale runtime for longer outages.

This UPS is not appropriate for high‑availability sites requiring continuous runtime beyond its basic battery capacity without external expansion, nor is it suitable for 208 V or 230 V distribution environments without the respective model variant.
