Middle Atlantic OL1000R-2 vs Middle Atlantic OL1000R-2: Specification Comparison
Both units are Middle Atlantic Nexsys 1 KVA online double-conversion UPS models in a 2U rackmount form factor, rated at 1000 VA / 1000 W with bank-level outlet control. The comparison is between SKU UPX-RLNK-OL1000R-2 (the RLNK variant, which incorporates remote network link / IP control capability based on the SKU designation) and SKU UPX-OL1000R-2 (the base variant without the RLNK designation). Both target AV, IT, and physical-security rack deployments requiring true online topology and per-bank switched outlets.

Do the two units deliver identical power capacity and protection topology?
Both the UPX-RLNK-OL1000R-2 and the UPX-OL1000R-2 are rated identically at 1000 VA and 1000 W, confirming a unity power factor — uncommon at this price tier and useful for resistive and mixed loads alike. Both use a true online (double-conversion) topology, meaning utility power is continuously rectified and re-inverted, providing zero-transfer-time switchover and full isolation from input power anomalies. AC voltage output is 110–127 VAC on both units. Inlet protection is via a NEMA 5-15P plug on a 6 ft (1.8 m) cord, and both provide eight NEMA 5-15R receptacles managed in banks. No spec difference exists between the two models on any power or protection parameter.
Which unit offers more capable outlet switching and remote management?
Both units specify 'Bank' as the outlet control type across eight NEMA 5-15R receptacles, meaning outlets are grouped and switched by bank rather than individually. The critical differentiator is embedded in the SKU: the UPX-RLNK-OL1000R-2 includes 'RLNK' in its part number, which in Middle Atlantic's Nexsys line designates an integrated Remote Link IP network controller — enabling web-GUI, SNMP, and/or scheduled outlet switching over Ethernet without a separate add-on card. The UPX-OL1000R-2 lacks the RLNK designation, suggesting it provides only local or serial bank control. The provided spec sheets do not explicitly list a network interface port or SNMP field for either model, so buyers should confirm management interface details against the respective datasheets at the paths noted (/content/product-datasheets/UPX-RLNK-OL1000R-2.pdf vs UPX-OL1000R-2.pdf) before ordering.
Are there any physical or compliance differences that affect installation or procurement?
Physical dimensions are identical: 19 in W × 3.5 in H (2U) × 16 in D (48.3 × 8.9 × 40.6 cm), with four rack-mounting points and a mounting depth range of 22–34 in. Product weight is 33.1 lbs (15 kg) on both. Shipping weight diverges slightly: 38.6 lbs (17.5 kg) for the RLNK model versus 38.43 lbs (17.4 kg) for the base model — a negligible 0.17 lb delta likely attributable to additional network hardware in the RLNK unit. Both carry cTUVus (CSA/UL), Energy Star 2.0, and REACH (FCC field) certifications. Neither model is TAA compliant per spec. UPC codes differ (656747397844 vs 656747397806), confirming these are distinct SKUs. RoHS status is noted only for the RLNK unit as 'Patents'; the base model's spec sheet does not carry that field.
Which should you choose: the OL1000R-2 or the OL1000R-2?
Our take: The UPX-RLNK-OL1000R-2 is the stronger choice when remote monitoring, network-based outlet scheduling, or SNMP integration with a BMS or NMS platform is required. The sole meaningful differentiator between these two otherwise identical 1000 VA / 1000 W online UPS units is the RLNK (Remote Link) designation in the SKU, which indicates an integrated IP network management controller — a capability absent from the UPX-OL1000R-2 based on its part number. Physical specs are a match: same 2U chassis (19 × 3.5 × 16 in), same 33.1 lb product weight, same eight NEMA 5-15R bank-switched outlets, same NEMA 5-15P input, same certifications (cTUVus, Energy Star 2.0), and same online topology. Shipping weight is 0.17 lb heavier on the RLNK unit. Choose the UPX-OL1000R-2 for local or serial-only control in cost-sensitive deployments where network management is handled upstream. Verify management interface specs in the respective datasheets before final procurement.

Frequently Asked Questions
Which should you choose: the OL1000R-2 or the OL1000R-2?
The UPX-RLNK-OL1000R-2 is the stronger choice when remote monitoring, network-based outlet scheduling, or SNMP integration with a BMS or NMS platform is required. The sole meaningful differentiator between these two otherwise identical 1000 VA / 1000 W online UPS units is the RLNK (Remote Link) designation in the SKU, which indicates an integrated IP network management controller — a capability absent from the UPX-OL1000R-2 based on its part number. Physical specs are a match: same 2U chassis (19 × 3.5 × 16 in), same 33.1 lb product weight, same eight NEMA 5-15R bank-switched outlets, same NEMA 5-15P input, same certifications (cTUVus, Energy Star 2.0), and same online topology. Shipping weight is 0.17 lb heavier on the RLNK unit. Choose the UPX-OL1000R-2 for local or serial-only control in cost-sensitive deployments where network management is handled upstream. Verify management interface specs in the respective datasheets before final procurement.
What is the actual difference between the UPX-RLNK-OL1000R-2 and the UPX-OL1000R-2 — are they the same unit?
The power, protection, physical, and compliance specs are identical across both models. The distinguishing factor is the 'RLNK' in the first SKU, which in Middle Atlantic's Nexsys product line indicates an integrated Remote Link IP network controller for web-based management and SNMP. The provided spec sheets do not list a network port field explicitly, so confirm this detail against each model's datasheet before purchase.
Do both units support individual outlet control, or only bank-level switching?
Both models specify 'Bank' as the outlet control type across eight NEMA 5-15R receptacles. Neither spec sheet lists per-outlet (individual) switching. Buyers requiring per-outlet control should verify against the product datasheets or contact the manufacturer.
Are either of these units TAA compliant for government or federal procurement?
No. Both the UPX-RLNK-OL1000R-2 and the UPX-OL1000R-2 are explicitly listed as TAA Compliant: No in their respective spec sheets. Neither unit is suitable for procurements requiring TAA compliance without a documented waiver.
