APC Smart-ups Ultra 2200VA 208+230V 1U with Lithium-ion Battery with Network - SRTL2K2RM1UWNC

APC by Schneider Electric SRTL2K2RM1UWNC Smart-UPS Ultra 2200VA 1U Rack Online UPS with Lithium-Ion and Network Card

Overview

The APC Smart-UPS Ultra SRTL2K2RM1UWNC is a 2200VA / 1950W online double-conversion rack UPS purpose-built for space-constrained 1U deployments where clean, conditioned power is non-negotiable. Unlike standby or line-interactive designs, the on-line topology means connected equipment never rides raw utility power — every watt passes through the inverter, eliminating transfer time and delivering true sine wave output regardless of what the grid is doing. Pair that with a lithium-ion battery that recharges to full capacity in roughly 90 minutes after a deep discharge, and you have a power platform suited for edge closets, branch server rooms, and compact data rack builds where downtime is measured in dollars per minute.

The integrated network management card (NMC3) ships pre-installed — no slot, no add-on purchase, no configuration lag. From day one, the UPS is reachable over the network for remote monitoring, outlet scheduling, and environmental threshold alerts, which matters on distributed deployments where someone isn't standing next to every rack. Combine that with the multi-function LCD control panel and audible/visible alarms prioritized by severity, and you have eyes on power health whether you're on-site or across the country.

Key Features

• On-Line Double-Conversion Topology: Every load watt passes through the inverter continuously — zero transfer time to battery, and a crest factor of 3:1 accommodates the inrush demands of switchers, servers, and variable-frequency drives without the UPS clipping or distorting. If input power degrades, the load never notices.
• True Sine Wave Output at 120V / 1950W: Active PFC power supplies (found in virtually every modern server and NVR) require a sine wave UPS or they risk tripping on simulated waveforms during outages. This UPS delivers a clean sine wave unconditionally — not just when on utility power.
• Lithium-Ion Battery, 90-Minute Recharge: The Li-Ion pack (replacement: APCRBC173-LI) recharges at up to 448W, returning to full capacity roughly 1.5 hours after a deep discharge. Lead-acid units in the same class typically need 4–8 hours. For facilities with multiple short outages per day — common near industrial equipment — that recovery window is meaningful.
• 1U Rack/Tower Convertible Form Factor at 35 lbs: The unit occupies a single rack unit and ships with rack mounting brackets and support rails. At 35.05 lbs, it's substantially lighter than equivalent lead-acid units, reducing rack floor-loading concerns in lightweight open-frame deployments. Tower conversion hardware is included if rack mounting isn't an option.
• 6 Output Receptacles (5x NEMA 5-20R + 1x NEMA L5-20R): The mixed outlet bank covers both standard and twist-lock connections — useful when you're mixing commodity PDU strips with a dedicated high-availability circuit for a primary server or NVR. The NEMA 5-20P input requires a 20A circuit, so confirm your panel before deploying.
• Embedded NMC3 with Environmental Monitoring: The pre-installed network management card supports remote outlet control, load shedding, event logging, and environmental sensor input — without consuming an expansion bay. This is the spec that separates the Ultra line from basic rack UPS options when you need managed power across branch locations.
• Internal Automatic and Manual Bypass: Automatic bypass keeps the load energized if the UPS internals fault; manual bypass lets you service or swap the unit without dropping the connected equipment. On a 1U unit sitting in a live production rack, that serviceability matters more than it sounds.
• Extendable Runtime Architecture: The SRTL2K2RM1UWNC supports external battery packs for extended runtime, so you're not locked into whatever the internal Li-Ion can deliver. Budget deployments start with the internal pack; mission-critical installations add external modules as the runtime requirement grows.
• 55 dB Acoustic Output: Quieter than many competing units in the 2000VA class — relevant in office-adjacent or open-plan spaces where fan noise accumulates across multiple rack-mounted devices.
• IP20 Protection Rating: Designed for controlled indoor environments — standard server rooms, IT closets, and clean manufacturing offices. Not rated for dusty or wet environments; plan accordingly for edge industrial locations.

Integration & Compatibility

The SRTL2K2RM1UWNC connects to management infrastructure via serial port, USB, and the embedded NMC3 Ethernet port — three independent paths for monitoring and control. UL/cUL listing and FCC Part 15 Class A certification cover the standard compliance requirements for commercial and light industrial deployments in the US and Canada. The unit meets UL 1778 and CSA C22.2 No.107.3-05, which are the relevant safety standards for rack-mount UPS equipment in North American data center and security infrastructure contexts. For integrators deploying rack UPS systems alongside IP cameras, NVRs, or access control servers, the NMC3 can integrate with leading power management platforms for centralized visibility. The USB and serial ports support direct shutdown coordination with connected servers — standard UPS daemon configurations on Windows, Linux, and VMware are supported via APC PowerChute software.

Before deploying, verify your rack has a 20A circuit available for the NEMA 5-20P input — a 15A circuit will not power this unit at rated load. The unit operates from 0–10,000 ft without derating; above that altitude, output capacity may be limited. Storage and transport are rated down to -15°C (5°F), which matters for cold-climate warehouse receiving or outdoor equipment staging.

Frequently Asked Questions

Q: Does the SRTL2K2RM1UWNC require a dedicated 20A circuit?

A: Yes. The input connection is a NEMA 5-20P, which requires a 20A outlet. A standard 15A circuit will not support the full 1950W / 2200VA rated load. Confirm your panel and receptacle before installation.

Q: What is the battery replacement part number for the SRTL2K2RM1UWNC?

A: The replacement lithium-ion battery for this unit is APCRBC173-LI. The Li-Ion pack recharges at up to 448W, returning to full capacity in approximately 1.5 hours after a deep discharge.

Q: Can the SRTL2K2RM1UWNC be used in tower orientation instead of rack-mount?

A: Yes. The unit ships as rack/tower convertible with the included mounting kit. Rack mounting brackets and support rails are included in the box; tower conversion hardware is also provided.

Q: Does the SRTL2K2RM1UWNC include a network management card, or is it sold separately?

A: The network management card (NMC3) with environmental monitoring is pre-installed — it ships embedded in the unit and is not a separate purchase. It provides Ethernet-based remote monitoring, outlet control, and environmental sensor support out of the box.

Q: What UPS topology does the SRTL2K2RM1UWNC use, and does it output a true sine wave?

A: This unit uses an on-line double-conversion topology and outputs a true sine wave at all times — not only during outages. This is required for active PFC power supplies found in modern servers, NVRs, and networking equipment. Simulated sine wave UPS units can cause those power supplies to fault during a switchover.

Q: Can runtime be extended with external battery packs on the SRTL2K2RM1UWNC?

A: Yes. The SRTL2K2RM1UWNC supports external battery pack modules for extended runtime beyond the internal lithium-ion capacity. This allows a phased investment — deploy with the internal pack initially and add external modules as runtime requirements grow.

Jerry Tildsen

The SRTL2K2RM1UWNC hits a specific target that most 1U rack UPS options miss: a 448W battery charging rate on a lithium-ion pack means you're back to full runtime in 90 minutes, not the 4–8 hours you'd wait on a comparably sized lead-acid unit. For branch locations with recurring short outages — a surprisingly common pattern near HVAC equipment, loading docks, or older electrical infrastructure — that recovery window is often the deciding spec.

Technical Highlights:

• On-Line Topology, Zero Transfer Time: Double-conversion means there's no switchover event at all — the load stays on inverter power continuously. For servers running active PFC supplies, this eliminates the clipping and micro-interruptions that line-interactive units can produce under fast input fluctuations.
• 1.5-Hour Li-Ion Recharge at 448W: Lead-acid units at 2200VA typically need 4–8 hours to recover from a deep discharge. The SRTL2K2RM1UWNC's 448W charge rate and lithium chemistry cut that to roughly 90 minutes — important when you're in a location that sees multiple utility events per shift.
• Embedded NMC3, No Slot Consumed: The pre-installed network management card leaves expansion capacity intact and eliminates the added cost of a separate NMC purchase. Remote outlet control, load shedding, and environmental sensor input are available from first power-on.

Deployment Considerations:

• The NEMA 5-20P input is a hard 20A requirement — verify your circuit before racking. Many older IT closets are wired for 15A, which will require an electrician visit before this unit can be commissioned at rated load.
• IP20 is an indoor-only rating. This unit is not appropriate for dusty manufacturing floors, outdoor enclosures, or uncontrolled environments — plan for a proper conditioned rack space or indoor equipment room.

This unit fits best in branch office server closets, compact security operations racks, and edge deployments where runtime extensibility, fast recharge, and remote management matter — and where 1U real estate is genuinely scarce. If your load is purely 120V and under 1950W with no need for network management, a simpler line-interactive unit may cost less; but for managed, mission-critical loads in a 1U footprint, the SRTL2K2RM1UWNC is the right tool.
