APC Smart-ups Lithium-ion 2200VA 120V with Smartconnect Port and L5-20R - SMTL2K2RM2UCL

APC by Schneider Electric SMTL2K2RM2UCL Lithium-Ion 2200VA 2U Rackmount UPS with SmartConnect

Overview

The APC Smart-UPS SMTL2K2RM2UCL is a 2200VA line-interactive rackmount UPS built around a lithium-ion battery platform and a SmartConnect management port — a configuration aimed squarely at security infrastructure racks, server closets, and surveillance deployments where runtime predictability and remote battery-health visibility matter. The line-interactive topology with automatic voltage regulation (AVR) keeps output voltage stable across a wide input range (82V–144V), meaning brownouts and swells that would otherwise stress NVRs, switches, and access control panels get corrected before they ever reach connected equipment. At 1980W of output power and a true sine-wave output, this unit is compatible with the active PFC power supplies found in most commercial-grade servers and NVR appliances — a detail that matters if you've ever had a stepped-approximation UPS trigger fault shutdowns on sensitive loads.

Key Features

• Line-Interactive Topology with AVR (82V–144V Input Range): Rather than switching to battery every time voltage dips, AVR corrects input deviations within that 62-volt window using the built-in boost/buck regulator. In facilities with unstable utility power — older buildings, shared circuits, or panel-heavy industrial environments — this dramatically extends battery life by keeping the batteries out of the regulation loop on minor voltage events.
• True Sine-Wave Output: Active PFC power supplies (standard in modern NVR appliances, rack servers, and managed switches) require sine-wave input to operate correctly. Stepped-approximation output from cheaper UPS units can cause load equipment to fault, draw excess current, or shut down unexpectedly. The SMTL2K2RM2UCL delivers a clean sine wave on battery — no compatibility asterisks for your critical load devices.
• 1980W Continuous Output: Plan your load carefully: 1980W is the usable ceiling. A rack with four 25W IP cameras, a 150W NVR, a 60W managed PoE switch, and a 40W access control panel sits well within budget. Leave 20–25% headroom for inrush currents on startup — particularly relevant if the UPS powers equipment that all comes up simultaneously after an outage.
• Lithium-Ion Battery Chemistry: Li-ion batteries charge faster, weigh significantly less than equivalent VRLA units, and tolerate higher ambient temperatures without accelerated degradation. For installations where the UPS lives in a warm telecom closet or where battery replacement logistics are a concern, the lithium-ion platform offers a meaningful operational advantage over traditional lead-acid designs.
• SmartConnect Port: The SmartConnect port enables cloud-based monitoring and remote management via APC's SmartConnect portal — useful for service providers managing multiple sites who need battery-health visibility without dispatching a technician. Proactive replacement alerts reduce the chance of discovering a degraded battery only after an actual outage.
• 530J Surge Energy Rating: 530 joules of surge protection covers typical line transients. This is adequate for standard commercial installations but is not a substitute for dedicated primary-side surge protection in environments with frequent lightning exposure or heavy industrial equipment on shared circuits.
• 6ms Transfer Time: At 6 milliseconds from utility loss to battery output, connected equipment with standard ATX power supplies and NVR platforms will bridge the gap without issue. Double-conversion UPS units offer 0ms transfer, which matters for extremely sensitive equipment — for most security and IT infrastructure, 6ms is well within tolerance.
• NEMA L5-20R and NEMA 5-20R Outlet Configuration: The mix of twist-lock (L5-20R) and straight-blade (5-20R) outlets serves installations that need to lock in critical loads (NVR, core switch) via twist-lock while powering ancillary equipment on standard outlets. Verify your NVR and switch power cords match before installation — L5-20R requires a mating twist-lock plug.
• 55 dB Noise Level: At 55 dB, this unit is audible in a quiet office but acceptable in a dedicated rack room or telecom closet. Not suited for open office deployments or executive conference rooms where ambient noise standards are strict.
• 50/60 Hz Input and Output Frequency: Accepts both 50Hz and 60Hz utility input and delivers regulated output at the same frequency — relevant for deployments in regions with 50Hz utility grids or for equipment imported from 50Hz markets.

Integration and Compatibility

The SMTL2K2RM2UCL accepts a NEMA 5-20R input plug, which requires a 20-amp circuit for full load capacity — confirm your panel and circuit breaker rating before deployment. The outlet mix (NEMA L5-20R twist-lock and NEMA 5-20R straight-blade) suits network video recorders, managed PoE switches, and access control panels commonly found in physical security racks. For broader context on sizing a UPS for surveillance infrastructure, a UPS and power protection selection guide can help match runtime and load requirements to the correct unit. The SmartConnect port integrates with APC's cloud monitoring platform — this requires an internet-connected network interface and appropriate firewall rules for outbound HTTPS traffic to APC's cloud endpoints. For deployments running NVR-based recording systems, ensure the UPS runtime at your actual load is sufficient to execute a graceful shutdown via the connected management software before battery reserves are exhausted.
