APC Smart-ups Ultra 2200VA 208+230V 1U with Lithium-ion Battery with Smartcon - SRTL2K2RM1UWC

APC by Schneider Electric SRTL2K2RM1UWC Smart-UPS Ultra 2200VA 1U Rack Online UPS with Lithium-Ion Battery

The APC Smart-UPS Ultra SRTL2K2RM1UWC is a 2200VA / 2200W double-conversion online UPS designed for enterprise IT and security infrastructure that cannot tolerate even a millisecond of power disturbance. Fitted into a single 1U rack profile and built around a lithium-ion battery pack, this unit trades the bulk of conventional VRLA-battery UPS systems for a dramatically smaller footprint without sacrificing runtime or power quality. If your rack density is climbing and you're struggling to fit adequate power protection into tight data closets, security head-end rooms, or colocation bays, the SRTL2K2RM1UWC addresses that problem directly.

Overview

Double-conversion (online) topology means utility power never reaches your load directly — incoming AC is continuously rectified to DC, then re-inverted to a clean sine wave output. The result is complete isolation from sags, surges, frequency drift, and noise. This is the correct architecture for network video recorders, high-density PoE switching infrastructure, and any load where a traditional standby or line-interactive UPS would still pass distorted utility power to sensitive electronics. The unit accepts input from 208 V to 240 V at 50 or 60 Hz, making it deployable across North American 208V three-phase-derived circuits and international 230V single-phase environments without re-cabling.

Key Features

• Double-Conversion Online Topology: All connected equipment runs off a continuously regenerated sine wave — not utility power. There is zero transfer time on outage because there is no transfer to make. For NVR arrays, access control servers, and network switching stacks where even a 10ms gap can trigger reboots or recording gaps, this matters.
• 2200W True Output Power: The SRTL2K2RM1UWC is rated at both 2200 VA and 2200 W, giving a 1.0 power factor — no derating penalty on modern server and switching loads that draw near-unity power factor. Older UPS units rated in VA only often deliver 60–70% of nameplate watts; this one delivers full nameplate.
• 97% Efficiency: At 97% efficiency this unit dissipates only 325 BTU/h at full load, roughly equivalent to a single 100W incandescent bulb in heat output. That matters in sealed security head-end rooms and data closets where HVAC capacity is limited — every BTU saved is cooling load you don't have to provision.
• Lithium-Ion Battery: Li-ion cells charge faster, tolerate more charge cycles before capacity degrades, and typically last significantly longer between replacements versus conventional VRLA lead-acid. In a 1U enclosure where a VRLA pack would dominate weight and volume, lithium-ion chemistry makes the form factor viable.
• 1U Rack Form Factor: A single rack unit is recoverable space in a dense deployment. Traditional UPS units at this power level typically require 2U or more. The 1U profile lets you protect a full 2200W of load without sacrificing an extra shelf in a 12U or 16U edge rack.
• Sine Wave Output, 2% THD: Output voltage total harmonic distortion is held to 2% — well within the tolerance of active PFC power supplies. Cheap UPS units producing stepped-approximation or modified sine waves can actually damage or destabilize active PFC supplies common in servers and PoE switches. This unit eliminates that risk.
• Crest Factor 3:1: A 3:1 crest factor means the inverter can handle loads with high peak-to-RMS current ratios — typical of rectifier-input power supplies — without clipping or tripping. Undersized crest factor is a common hidden failure mode when UPS units are loaded with switching power supplies.
• 1600 J Surge Energy Rating: The 1600 J surge suppression rating absorbs significant transient energy from utility events before it reaches connected equipment. Pair this with the online topology and surge events become a non-issue for connected loads.
• Dual Output Connector Types — C13 and C19: The SRTL2K2RM1UWC provides both C13 (standard IEC for 1U/2U servers, switches, patch panels) and C19 (high-draw devices, PDUs, large switching platforms) outlets. Mixed outlet types eliminate the need for adapters in heterogeneous equipment bays.
• SmartConnect Integration: The included SmartConnect capability provides cloud-based monitoring and management — relevant for multi-site deployments where a physical operations team cannot be on-site to check UPS status. Remote visibility into battery state, load percentage, and event logs reduces truck rolls for routine status checks.
• 55 dB Noise Level: At 55 dB, this unit is audible but not disruptive in a standard server room or security operations center. It is not suitable for open-office or classroom deployments where quiet operation is a hard requirement, but for any closed equipment room it is a non-issue.
• Audible Alarms: On-battery and fault conditions trigger audible alarms — a basic but essential feature for unmanned equipment rooms where visual indicator checks are infrequent.

Integration and Compatibility

The 208–240V input range covers the most common power delivery configurations in enterprise IT: 208V from three-phase 120/208V panels (standard in US data centers and server rooms) and 230V single-phase from international or mixed-voltage facilities. The UPS and power protection category includes line-interactive and standby alternatives for lower-criticality loads; the SRTL2K2RM1UWC is the appropriate choice when load criticality demands zero transfer time and complete isolation from utility power quality issues. For deployments integrating PoE network switches and NVR stacks, the dual C13/C19 outlet mix accommodates both standard IEC equipment and higher-draw PDUs without adapters. SmartConnect enables integration with APC's cloud monitoring platform, and the unit supports standard UPS signaling for graceful server shutdown via network management card or USB interface — confirm NMC compatibility with your specific management infrastructure before deployment.

Frequently Asked Questions

Q: What is the output power capacity of the SRTL2K2RM1UWC, and does it derate for high power-factor loads?

A: The SRTL2K2RM1UWC is rated at 2200 VA and 2200 W — a 1.0 power factor rating. There is no derating for near-unity power factor loads such as modern servers and network switches. Full nameplate wattage is available to connected equipment.

Q: What input voltage range does the SRTL2K2RM1UWC accept?

A: The unit accepts input from 208 V to 240 V at 50 or 60 Hz, covering both 208V three-phase-derived circuits common in US enterprise environments and 230V single-phase circuits used internationally.

Q: Why choose double-conversion (online) topology over line-interactive for this application?

A: Double-conversion means your load runs off a continuously regenerated inverter output — utility power never reaches the load directly. There is zero transfer time on outage, and all input power quality issues (sags, surges, frequency drift, noise) are fully isolated. Line-interactive UPS units only correct voltage; they pass through frequency and noise, and introduce a brief transfer gap on full outage. For NVRs, servers, and critical switching infrastructure, double-conversion is the correct topology.

Q: What type of battery does the SRTL2K2RM1UWC use, and why does it matter?

A: The SRTL2K2RM1UWC uses a lithium-ion (Li-ion) battery pack. Li-ion charges faster, tolerates more charge/discharge cycles before capacity degradation, and typically achieves a longer service life than conventional VRLA lead-acid batteries. The lithium-ion chemistry also enables the 1U form factor — a VRLA pack at equivalent capacity would require significantly more rack space and weight.

Q: What output connector types are available on the SRTL2K2RM1UWC?

A: The unit provides both C13 and C19 IEC output connectors. C13 is the standard connector for 1U/2U servers, switches, and most rack equipment. C19 supports higher-draw devices and PDUs. The mixed outlet configuration avoids adapters in heterogeneous equipment bays.

Q: How efficient is the SRTL2K2RM1UWC, and what does that mean for cooling requirements?

A: The unit operates at 97% efficiency and dissipates 325 BTU/h at full load — a low heat output for a 2200W online UPS. In sealed or capacity-constrained equipment rooms, this significantly reduces the cooling load compared to less efficient UPS designs.

James Everett

The SRTL2K2RM1UWC is the unit I recommend when an integrator needs true double-conversion protection in a space-constrained rack and cannot afford to give up 2U or more to a VRLA-based system. The 97% efficiency figure is not a marketing number — at 2200W full load, you are dissipating only 325 BTU/h, which is meaningful in a 6U or 9U security head-end rack where every BTU contributes to thermal headroom.

Technical Highlights:

• 1.0 Power Factor (2200W / 2200VA): No derating. Server, switching, and NVR loads running at near-unity power factor pull exactly the watts the nameplate says. Older UPS units at 0.6–0.7 PF rating would require a 3–3.5 kVA unit to deliver the same real watts.
• 2% Output THD, Sine Wave: Active PFC power supplies — standard on any server or managed switch manufactured in the last decade — require a clean sine wave. The 2% THD output keeps power supply EMI filters and PFC stages operating within spec; a modified sine wave source would force derating or cause instability.
• 1600 J Surge Rating + Online Isolation: Because the load never touches utility power, surge events that would pass through a standby UPS are absorbed at the rectifier stage. The 1600 J rating handles residual transients that reach the input before the rectifier clamps them.

Deployment Considerations:

• Input voltage range (208–240V) requires a dedicated 208V or 230V feed — this unit will not operate on standard North American 120V branch circuits. Confirm panel capacity and circuit breaker sizing before rack installation.
• At 55 dB operational noise, the SRTL2K2RM1UWC is appropriate for closed equipment rooms only. Do not spec this for open-office IT closets or AV server racks in noise-sensitive spaces.

The SRTL2K2RM1UWC fits best in enterprise security operations centers, 1U-constrained edge data closets, and multi-site deployments where SmartConnect remote monitoring reduces the need for on-site power status checks — specifically where 208V infrastructure is already in place and rack space is at a premium.
