APC Smart-UPS SMTL1000RM3UC Lithium-Ion 1000VA RM 3U 120V with SmartConnect

Product Overview

The APC Smart-UPS SMTL1000RM3UC is a 1000VA / 900W lithium-ion rackmount UPS with SmartConnect cloud monitoring, designed for commercial AV and IT deployments where reduced weight, longer battery life, and faster recharge time are prioritized over traditional lead-acid designs. The 3U rackmount chassis houses a lithium-ion battery system that delivers significantly lighter weight and a longer service life than equivalent lead-acid UPS units, reducing long-term battery replacement costs and rack weight loads in commercial AV installations. SmartConnect cloud monitoring enables remote management without dedicated software.

Product Description

Lithium-ion battery chemistry gives the SMTL1000RM3UC several practical advantages for commercial AV rack deployments: the battery lasts up to 2–3 times longer than lead-acid equivalents, reducing replacement frequency and associated maintenance costs. The unit weighs significantly less than lead-acid 1000VA rackmount UPS units, making it easier to install in overhead or elevated rack positions common in AV system design. SmartConnect cloud connectivity enables AV integrators and facilities managers to monitor battery health, receive alerts, and track runtime estimates remotely. The 3U chassis fits standard 19-inch racks and ships with mounting hardware. Pure sine wave output protects active PFC power supplies across the full range of professional AV and IT equipment. Automatic voltage regulation corrects brownouts and overvoltages without battery engagement, further extending the already-long lithium-ion battery service life.

Frequently Asked Questions

How long does the lithium-ion battery last compared to lead-acid?

APC rates the SMTL lithium-ion battery for up to 10 years of service under normal operating conditions, compared to 3–5 years for typical lead-acid UPS batteries. This significantly reduces lifecycle replacement costs in commercial AV deployments.

Is the battery user-replaceable?

Yes. The lithium-ion battery module in the SMTL1000RM3UC is designed for user replacement, though APC recommends following the replacement procedure in the installation guide or engaging a qualified technician.

Why does the SMTL series occupy 3U instead of 2U?

The 3U chassis accommodates the lithium-ion battery module design, which provides the longer service life and lower weight benefits at a slight increase in rack height versus the 2U lead-acid models.

Is the SMTL1000RM3UC compatible with external battery packs?

The SMTL series lithium-ion models do not support external lead-acid battery packs. Runtime is determined by the internal lithium-ion battery. Consult Creation Networks for runtime sizing guidance.
