APC by Schneider Electric SMTL1000RM2UCNC Short-Depth 1000VA Lithium-Ion Rack UPS
Overview
The APC by Schneider Electric SMTL1000RM2UCNC is a 1000VA / 800W lithium-ion uninterruptible power supply in a short-depth 2U rack form factor — purpose-built for environments where cabinet depth is limited and battery weight is a constraint. At 35.9 lb, it is notably lighter than comparable VRLA rack UPS units, and the Li-Ion chemistry delivers a substantially longer service life before battery replacement. The integrated SmartConnect port provides cloud-based monitoring without requiring a separate network management card, making remote visibility straightforward in distributed or multi-site deployments.
This unit targets server rooms, network closets, edge compute deployments, and security infrastructure racks where reliable 120V conditioned power is non-negotiable and floor space is tight.
Key Features
- 1000VA / 800W Capacity: Supports meaningful mixed loads — a pair of PoE network switches, a small NVR, or a compact server — without the overhead of a larger 1500VA chassis occupying more rack space.
- Lithium-Ion Battery Chemistry: Li-Ion cells deliver a longer usable service life compared to sealed lead-acid alternatives and handle partial state-of-charge cycling better, reducing battery replacement frequency in always-on rack environments.
- Short-Depth 2U Chassis: The compact depth at 3.39 in (8.6 cm) in profile accommodates shallow wall-mount enclosures, short-depth racks, and data closets where standard-depth UPS units simply do not fit.
- SmartConnect Port: Cloud-connected monitoring via the SmartConnect portal gives you runtime status, battery health, and alert notifications without purchasing a separate network management card — a meaningful cost and complexity reduction for multi-site operators.
- 120V Input and Output: Matched 120V I/O integrates directly into standard North American single-phase infrastructure with no step-up or step-down transformer required.
- 8 ft (2.4 m) Input Cable: The included 8-foot power cable provides enough reach to a PDU or wall circuit without an extension — useful in deep racks where the cable run to the rear PDU adds up.
- 35.9 lb (16.3 kg) Unit Weight: Lighter than equivalent-capacity VRLA units, reducing the risk of exceeding rack weight limits in wall-mount or lighter-duty enclosures.
Integration and Compatibility
The SMTL1000RM2UCNC connects to APC's SmartConnect cloud platform for remote monitoring and management. It operates on standard 120V North American circuits. For local or on-premise power management software integration, APC's PowerChute software is compatible with SmartConnect-equipped UPS units — verify the current PowerChute version against your OS environment before deployment. The unit fits standard EIA 19-inch rack rails in a 2U footprint.
Frequently Asked Questions
Q: What is the output capacity of the SMTL1000RM2UCNC?
A: The unit is rated at 1000VA / 800W output at 120V.
Q: What battery type does the SMTL1000RM2UCNC use?
A: It uses Lithium-Ion (Li-Ion) battery chemistry, which offers a longer service life and lighter weight compared to sealed lead-acid alternatives.
Q: How much does the SMTL1000RM2UCNC weigh?
A: 35.9 lb (16.3 kg) — lighter than comparable VRLA rack UPS units of the same capacity.
Q: Does the SMTL1000RM2UCNC require a separate network management card for remote monitoring?
A: No. The integrated SmartConnect port provides cloud-based monitoring and alerting without an add-on card.
Q: What rack space does the SMTL1000RM2UCNC occupy?
A: It occupies 2U in a standard 19-inch EIA rack and is designed with a short-depth chassis for shallow enclosures.
The SMTL1000RM2UCNC is the unit I reach for when a customer has a shallow wall-mount enclosure or a short-depth open frame rack and needs reliable 120V UPS coverage without the bulk or weight of a standard VRLA. The 35.9 lb Li-Ion chassis is a real differentiator in those installs — standard 1000VA VRLA units routinely hit 50–60 lb, which can push a wall-mount enclosure past its rated load before you've added switches and patch panels.
Technical Highlights:
- 800W / 1000VA Output: Sufficient for a compact security NVR, a managed PoE switch stack, and a small edge server — the load profile that shows up most in mid-size commercial security closets.
- Li-Ion Battery: Longer cycle life than VRLA means fewer battery replacement events over a multi-year service contract — a real TCO factor when you're maintaining dozens of remote closets.
- SmartConnect Cloud Port: Built-in remote monitoring without a network card purchase. For multi-site operators managing 10–50 closets, that card cost adds up fast; SmartConnect eliminates it.
Deployment Considerations:
- Confirm your rack or enclosure depth accommodates the chassis before ordering — the short-depth form factor is the reason to choose this unit, but verify the rail kit compatibility with your specific enclosure brand.
- At 800W true output, back-calculate your connected load carefully — UPS efficiency curves mean you should target 60–80% of rated wattage for optimal runtime and battery longevity, so plan for no more than ~480–640W of sustained connected load.
This unit is the right fit for commercial security infrastructure closets — NVR plus switch plus access control panel — in retail branch locations, school buildings, or any site where cabinet depth and total rack weight are real constraints, not afterthoughts.
