Middle Atlantic S2200R vs APC by Schneider Electric SRT2200RMXLA-NC: Specification Comparison
Both the Middle Atlantic UPS-S2200R and the APC SRT2200RMXLA-NC are 2200VA, 2U rack-mount uninterruptible power supplies targeting the same physical footprint and VA class. Buyers in the physical-security and AV-integration space routinely cross-shop these units when specifying rack power backup for NVR/VMS servers, network switches, and access-control head-ends. The comparison spans UPS topology and output quality, physical and environmental fit, and battery/runtime extensibility — three axes that drive most real procurement decisions in this category.

Which UPS delivers cleaner, more reliable output power under load?
The APC SRT2200RMXLA-NC uses a Double Conversion Online topology with a sine wave output, less than 2% total harmonic distortion, and a 3:1 crest factor. In double-conversion mode, connected loads run entirely off the inverted output at all times — the raw utility feed never reaches the load directly — providing zero transfer time on utility failure and continuous voltage regulation. Output frequency is actively regulated to 50/60 Hz ±3 Hz synchronized to mains.
The Middle Atlantic UPS-S2200R specifies its surge protection type only as 'Basic' and does not disclose UPS topology, waveform type, transfer time, or output THD in the provided specification set. For buyers whose loads — particularly SMPS-based network equipment, IP cameras, and NVR platforms — are sensitive to waveform quality or require zero-transfer-time protection, the SRT2200RMXLA-NC's double-conversion architecture and documented sine wave output represent a meaningful, verifiable advantage. The UPS-S2200R's topology and waveform cannot be evaluated from available specs.
How do the two units compare on physical fit, weight, and environmental ratings?
Both units occupy 2U of rack space. The Middle Atlantic UPS-S2200R is deeper at 16.5 in (41.9 cm) versus the APC SRT2200RMXLA-NC, whose depth is not explicitly listed in the provided specs (only height of 3.35 in / 8.5 cm is given). The S2200R specifies a minimum mounting depth of 19 in and a maximum of 32 in, and includes 2 mounting points; the SRT2200RMXLA-NC notes front mounting location, horizontal orientation, and that two-post mounting is not supported (value: 0). Width is 19 in for the S2200R; the APC unit's width is not stated in the provided specs.
On weight, the S2200R ships at 62 lb (28.1 kg) versus the SRT2200RMXLA-NC at 55.01 lb (24.95 kg) — a 7 lb difference relevant for rail load calculations. The APC unit provides documented environmental ratings: 0–95% RH non-condensing operating humidity, 0–10,000 ft operating altitude, –4 to 122°F storage temperature range, and an IP20 ingress protection rating. The Middle Atlantic S2200R does not disclose operating humidity, altitude, or storage temperature ranges in the provided specifications. For deployments in non-climate-controlled IDF closets or elevated-altitude sites, the APC's documented environmental envelope is the only verifiable data available.
Which unit offers more flexibility for battery runtime and replacement planning?
The APC SRT2200RMXLA-NC ships with one internal lead-acid battery module (72V, 306 VAh, 102W charge power), rated 3–5 year battery life with a typical recharge time of 3 hours. It is explicitly extensible: up to 10 external SRT72RMBP battery packs are supported, scaling runtime capacity from 918 VAh (1 pack) to 6,426 VAh (10 packs). Replacement batteries are identified as APCRBC141 and SRT72RMBPUS. The rated output is 1800W / 2200VA.
The Middle Atlantic UPS-S2200R specifies an 8-outlet, 2200VA, corded unit with a 10 ft (3.1 m) cord. Battery type, battery voltage, rated watt output, recharge time, battery life expectancy, replacement battery part numbers, and runtime extensibility options are not disclosed in the provided specification set. For installers who need to plan battery replacement cycles, calculate runtime at a known watt load, or expand runtime for extended outages, the APC SRT2200RMXLA-NC provides the necessary data; equivalent data for the S2200R is absent from the provided specs.
Which should you choose: the S2200R or the SRT2200RMXLA-NC?
Our take: The SRT2200RMXLA-NC is the stronger choice when output power quality, documented environmental ratings, and runtime extensibility are decision criteria. Three concrete spec deltas: (1) the APC unit specifies Double Conversion Online topology with <2% THD sine wave output — the S2200R discloses only 'Basic' surge protection with no topology or waveform data; (2) the APC unit is 7 lb lighter (55.01 lb vs. 62 lb) and carries explicit IP20, 0–10,000 ft altitude, and 0–95% RH ratings absent from the S2200R spec sheet; (3) the APC unit supports up to 10 external battery packs (up to 6,426 VAh) with named replacement batteries — the S2200R provides no battery or runtime extensibility data. The S2200R may suit basic rack-power-strip replacement applications where deeper rack clearance (up to 32 in) or Middle Atlantic ecosystem integration drives the decision, but buyers cannot verify its protection quality from available specs alone.

Frequently Asked Questions
Which should you choose: the S2200R or the SRT2200RMXLA-NC?
The SRT2200RMXLA-NC is the stronger choice when output power quality, documented environmental ratings, and runtime extensibility are decision criteria. Three concrete spec deltas: (1) the APC unit specifies Double Conversion Online topology with <2% THD sine wave output — the S2200R discloses only 'Basic' surge protection with no topology or waveform data; (2) the APC unit is 7 lb lighter (55.01 lb vs. 62 lb) and carries explicit IP20, 0–10,000 ft altitude, and 0–95% RH ratings absent from the S2200R spec sheet; (3) the APC unit supports up to 10 external battery packs (up to 6,426 VAh) with named replacement batteries — the S2200R provides no battery or runtime extensibility data. The S2200R may suit basic rack-power-strip replacement applications where deeper rack clearance (up to 32 in) or Middle Atlantic ecosystem integration drives the decision, but buyers cannot verify its protection quality from available specs alone.
Is the UPS-S2200R or the SRT2200RMXLA-NC better for protecting sensitive NVR and network equipment?
Based on the provided specifications, the SRT2200RMXLA-NC is the verifiable choice for sensitive loads. It documents a Double Conversion Online topology, sine wave output, and less than 2% total harmonic distortion — characteristics that eliminate transfer time and deliver conditioned power continuously. The UPS-S2200R lists only 'Basic' surge protection; its topology and waveform are not disclosed in the available spec data, so its suitability for sensitive electronics cannot be confirmed from specs alone.
Can either unit support extended runtime for longer outages?
Only the APC SRT2200RMXLA-NC explicitly supports runtime extension. Its spec sheet lists up to 10 external SRT72RMBP battery packs, scaling total capacity from 918 VAh (1 pack) to 6,426 VAh (10 packs), with a 3-hour typical recharge time and 3–5 year battery life rating. The Middle Atlantic UPS-S2200R does not disclose battery type, battery capacity, or external battery expansion options in the provided specifications.
Which unit fits better in a shallow or two-post rack?
The Middle Atlantic UPS-S2200R specifies a mounting depth range of 19–32 in and a product depth of 16.5 in, with 2 mounting points. The APC SRT2200RMXLA-NC specifies front-mount, horizontal, rack-mounted positioning and explicitly notes two-post mounting is not supported (value: 0). Product depth for the SRT2200RMXLA-NC is not provided in the available specs. For two-post racks, the S2200R does not disqualify itself on that point, while the APC unit's spec explicitly excludes two-post use.
