Middle Atlantic RLNK-1500R-2 vs Middle Atlantic OL1500R: Specification Comparison
Both products are 2RU, 1500VA rack-mount UPS units from Middle Atlantic, occupying the same form factor and apparent capacity class. The UPX-RLNK-1500R-2 is part of the NEXSYS line with integrated RLNK remote bank control, while the UPS-OL1500R is from the Premium Online Series featuring double-conversion topology. Buyers evaluating either unit for AV, security, or IT rack deployments will want to weigh UPS topology, output specifications, load capacity, and physical integration before committing to one platform.

Which unit provides stronger power conditioning and what are the confirmed output ratings?
The UPS-OL1500R specifies Online Double Conversion topology, meaning incoming AC is continuously converted to DC and back to AC, providing zero-transfer-time switchover and full isolation from line disturbances. Its rated output is 1500VA / 1350W at 120VAC, 15A, with 8 output receptacles (NEMA 5-15R).
The UPX-RLNK-1500R-2 does not specify a UPS topology (line-interactive, standby, or double-conversion) anywhere in the provided specs. Its listed output voltage is 36VDC — not an AC output — which is atypical for a standalone UPS and may indicate this unit functions as a DC power plant or a UPS with integrated DC distribution rather than a conventional AC-output UPS. Output wattage, VA load rating, and outlet count are not provided in the available specifications.
For buyers requiring confirmed AC output with a known wattage ceiling and topology guarantee, only the UPS-OL1500R provides those figures in the supplied data.
How do the two units compare on physical footprint, weight, and operating environment?
Both units share identical rack form factor (2RU, 19 in wide, 3.46 in tall) and the same four mounting points. Operating temperature is identical at 32°–104°F (0°–40°C) for both.
Depth differs slightly: the UPX-RLNK-1500R-2 is 16 in (40.6 cm) deep versus the UPS-OL1500R at 15.57 in (39.6 cm). The UPS-OL1500R is heavier at 47.7 lbs (21.6 kg) versus 44.1 lbs (20 kg) for the UPX-RLNK-1500R-2, consistent with the additional transformer mass typical of double-conversion designs.
The UPS-OL1500R also specifies a mounting depth range of 20.7 in minimum to 36.2 in (92 cm) maximum, which is relevant for open-frame and deeper rack enclosures. No equivalent mounting depth range is specified for the UPX-RLNK-1500R-2.
Cord length differs: UPX-RLNK-1500R-2 ships with a 6 ft (1.8 m) power cord; UPS-OL1500R ships with a 10 ft (3.1 m) cord — a meaningful difference when the rack is distant from a wall outlet.
What management, control, and compliance features does each unit offer?
The UPX-RLNK-1500R-2 explicitly includes NEXSYS UPS technology and RLNK bank control in its product designation, indicating integrated remote outlet switching or sequencing capability — a feature relevant for AV and security integrators who need per-bank load management or controlled restart sequences. Input voltage is confirmed at 120VAC. Country of origin is China. No TAA compliance on either unit.
The UPS-OL1500R carries an FCC / RoHS listing per the provided specs. No RLNK or equivalent remote bank control feature is listed. No country of origin is specified.
Neither unit's available specs reference SNMP, network management cards, USB/serial monitoring ports, or software compatibility — buyers requiring those features should consult the respective datasheets (/content/product-datasheets/UPX-RLNK-1500R-2.pdf and /content/product-datasheets/UPS-OL1500R.pdf) for confirmation.
Which should you choose: the RLNK-1500R-2 or the OL1500R?
Our take: The UPS-OL1500R is the stronger choice when confirmed double-conversion power conditioning, a known wattage ceiling, and regulatory compliance listings are required. Its Online Double Conversion topology guarantees zero transfer time and full line isolation — neither of which is confirmed for the UPX-RLNK-1500R-2 based on available specs. The OL1500R delivers a documented 1350W / 1500VA at 120VAC with 8 outlets, carries RoHS certification, and ships with a longer 10 ft cord. By contrast, the UPX-RLNK-1500R-2 lists a 36VDC output rather than AC, which may indicate a fundamentally different product architecture (DC power plant or hybrid DC-distribution UPS); its wattage rating and outlet count are absent from the provided data. The RLNK-1500R-2 is the appropriate platform for Middle Atlantic NEXSYS ecosystems requiring remote bank switching. Buyers should confirm output architecture with the datasheet before substituting one for the other.

Frequently Asked Questions
Which should you choose: the RLNK-1500R-2 or the OL1500R?
The UPS-OL1500R is the stronger choice when confirmed double-conversion power conditioning, a known wattage ceiling, and regulatory compliance listings are required. Its Online Double Conversion topology guarantees zero transfer time and full line isolation — neither of which is confirmed for the UPX-RLNK-1500R-2 based on available specs. The OL1500R delivers a documented 1350W / 1500VA at 120VAC with 8 outlets, carries RoHS certification, and ships with a longer 10 ft cord. By contrast, the UPX-RLNK-1500R-2 lists a 36VDC output rather than AC, which may indicate a fundamentally different product architecture (DC power plant or hybrid DC-distribution UPS); its wattage rating and outlet count are absent from the provided data. The RLNK-1500R-2 is the appropriate platform for Middle Atlantic NEXSYS ecosystems requiring remote bank switching. Buyers should confirm output architecture with the datasheet before substituting one for the other.
Is the UPX-RLNK-1500R-2 or UPS-OL1500R better for protecting sensitive AV or security equipment from power disturbances?
Based on the provided specs, the UPS-OL1500R is the only unit with a confirmed Online Double Conversion topology, which provides continuous AC output regeneration and zero transfer time — the highest level of power conditioning available in a UPS. The UPX-RLNK-1500R-2 does not specify a topology in the available data, and its listed 36VDC output suggests a different architecture. Buyers requiring clean, conditioned AC output should verify the RLNK-1500R-2's actual output type against its datasheet before selecting it for sensitive loads.
Does either unit support remote outlet switching or load sequencing?
The UPX-RLNK-1500R-2 explicitly includes RLNK bank control as a named feature, indicating remote outlet switching or sequencing capability within the Middle Atlantic NEXSYS ecosystem. The UPS-OL1500R's provided specifications do not mention remote bank control or outlet switching. Installers who require controlled power sequencing for AV or security racks should factor this distinction into their selection.
Which unit fits a shallower rack or requires less clearance behind the rails?
The UPS-OL1500R specifies a minimum mounting depth of 20.7 in and a maximum of 36.2 in (92 cm), giving clear guidance for rack compatibility. Its chassis depth is 15.57 in (39.6 cm). The UPX-RLNK-1500R-2 is slightly deeper at 16 in (40.6 cm) and provides no minimum/maximum mounting depth specification. For racks with tight depth constraints, consult both datasheets to confirm rail compatibility.
