Middle Atlantic UPX-1000R-2 vs Middle Atlantic RLNK-1000R-2: Specification Comparison
Both the Middle Atlantic UPX-1000R-2 and UPX-RLNK-1000R-2 are 1000VA NEXSYS rack-mount UPS systems designed for AV and security rack infrastructure. They share the same form factor, power ratings, and physical chassis, but differ by one key feature: the RLNK-1000R-2 adds individual outlet-bank remote control (RLNK) capability over the base UPX-1000R-2. This comparison addresses the practical tradeoffs in manageability, physical installation, and compatibility for integrators evaluating both models.

Which model offers more granular outlet and load management?
The UPX-1000R-2 identifies its special feature simply as 'NEXSYS UPS' with no mention of remote outlet switching in the provided specs. The UPX-RLNK-1000R-2 carries the same 'NEXSYS UPS' designation but its model name and SKU embed 'RLNK,' indicating bank-level outlet control as a differentiating feature per its product title ('Rlnk Bank Control'). Neither spec sheet quantifies the number of controllable banks or communication interface (e.g., network card, USB, serial) from the data provided, so integrators should consult the respective datasheets at /content/product-datasheets/UPX-1000R-2.pdf and /content/product-datasheets/UPX-RLNK-1000R-2.pdf before specifying.
For deployments requiring remote reboot of individual device groups — IP cameras, NVRs, or network switches — the RLNK designation on the B model is the operative differentiator. The base UPX-1000R-2 does not indicate this capability in its provided specs.
Are the two units interchangeable in an existing rack bay?
Both units are dimensionally identical per spec: 19 in (48.3 cm) wide, 3.46 in (8.8 cm) tall (2 RU), 16 in (40.6 cm) deep, with 4 mounting points and a 6 ft (1.8 m) input cord. Both use a NEMA 5-15P plug and NEMA 5-15R receptacles, and both mount to standard 19-inch rack rails.
Unit weight is identical at 44.1 lbs (20 kg), but shipping weight differs: the UPX-1000R-2 ships at 50.26 lbs (22.8 kg) versus 52 lbs (23.6 kg) for the UPX-RLNK-1000R-2 — a 1.74 lb difference attributable to additional RLNK hardware or packaging. Floor load and rack weight budgets are essentially equal in practice. Both require a standard 15-amp, 120 VAC circuit.
Do the two models deliver the same power protection and operate under the same environmental conditions?
Both units share identical power specifications from the provided data: 120 VAC input, 36 VDC output voltage noted, NEMA 5-15P/R plug and receptacle pairing, and a 1000VA capacity implied by the product class and naming. Operating temperature range is identical at 32°–104°F (0°–40°C) for both.
Neither spec sheet provides explicit runtime curves, battery capacity (Ah), waveform type (sine wave vs. stepped approximation), transfer time, or overcurrent protection details. These are critical UPS selection parameters for sensitive equipment and must be obtained from the manufacturer datasheets. Country of origin is China for both; neither unit is TAA compliant per specs — relevant for federal or government-funded installations subject to Trade Agreements Act requirements.
Which should you choose: the UPX-1000R-2 or the RLNK-1000R-2?
Our take: The UPX-RLNK-1000R-2 is the stronger choice when the installation requires remote, software-driven control of individual outlet banks for selective device rebooting or load shedding. The two units are physically interchangeable — identical dimensions (19 × 3.46 × 16 in, 2 RU), identical unit weight (44.1 lbs), identical input/output receptacle types (NEMA 5-15P/R), and the same 120 VAC / 1000VA power class. The sole spec delta from the provided data is shipping weight: the RLNK model ships 1.74 lbs heavier (52 lbs vs. 50.26 lbs), consistent with added internal or panel hardware. For basic backup power in a static rack with no remote management requirement, the UPX-1000R-2 is a functionally equivalent platform. Neither unit is TAA compliant, which disqualifies both for TAA-restricted procurement. Integrators should verify outlet-bank count, communication interface, runtime, and waveform type in the respective datasheets before final specification.

Frequently Asked Questions
Which should you choose: the UPX-1000R-2 or the RLNK-1000R-2?
The UPX-RLNK-1000R-2 is the stronger choice when the installation requires remote, software-driven control of individual outlet banks for selective device rebooting or load shedding. The two units are physically interchangeable — identical dimensions (19 × 3.46 × 16 in, 2 RU), identical unit weight (44.1 lbs), identical input/output receptacle types (NEMA 5-15P/R), and the same 120 VAC / 1000VA power class. The sole spec delta from the provided data is shipping weight: the RLNK model ships 1.74 lbs heavier (52 lbs vs. 50.26 lbs), consistent with added internal or panel hardware. For basic backup power in a static rack with no remote management requirement, the UPX-1000R-2 is a functionally equivalent platform. Neither unit is TAA compliant, which disqualifies both for TAA-restricted procurement. Integrators should verify outlet-bank count, communication interface, runtime, and waveform type in the respective datasheets before final specification.
Can I swap the UPX-1000R-2 for the UPX-RLNK-1000R-2 in an existing rack without mechanical changes?
Yes, based on the provided specs. Both units share identical rack dimensions (19 × 3.46 × 16 in, 2 RU, 4 mounting points) and the same NEMA 5-15P plug on a 6 ft cord, so no mechanical or wiring changes are required at the rack level. Verify that any management software or UPS communication cabling required by the RLNK model is accounted for in the installation plan.
Does the UPX-1000R-2 or UPX-RLNK-1000R-2 qualify for government or federal procurement under TAA?
Neither unit qualifies. Both are listed as TAA Compliant: No in the provided specifications and both are manufactured in China. Integrators bidding on TAA-restricted contracts — federal, DoD, or GSA schedule work — must source a compliant alternative.
What specs are missing from this comparison that I should confirm before purchasing either UPS?
The provided spec sheets do not include runtime at full or half load, battery capacity (Ah), output waveform type (pure sine wave vs. simulated sine), transfer time to battery, number and layout of output receptacles, or the communication interface type (network card, USB, dry contact) for the RLNK model's outlet control. These are decision-critical for protecting sensitive IP cameras, NVRs, and access control hardware. Consult the datasheets at /content/product-datasheets/UPX-1000R-2.pdf and /content/product-datasheets/UPX-RLNK-1000R-2.pdf or contact Middle Atlantic directly.
