Middle Atlantic UPX-EXPANRUN-OL10 vs Middle Atlantic RLNK-1000R-2: Specification Comparison
Both the Middle Atlantic UPX-EXPANRUN-OL10 and the UPX-RLNK-1000R-2 are 1000VA, 2RU rack-mount online (double-conversion) UPS units from Middle Atlantic's Nexsys platform, sharing the same 120V AC input, NEMA 5-15 plug/receptacle, 16-inch depth, and 19-inch width. The key distinction is function: the UPX-EXPANRUN-OL10 is a run-time expansion battery unit (add-on), while the UPX-RLNK-1000R-2 is a remote link bank-control UPS (standalone with remote power management). Buyers cross-shopping these two are likely evaluating runtime extension versus integrated network/bank switching capability.

What is each unit's primary function and UPS topology—and how does that affect deployment?
The UPX-EXPANRUN-OL10 is explicitly a run-time expansion unit for the Nexsys UPS platform, not a standalone UPS. Its spec sheet designates it as a battery/runtime add-on with a 24 VDC output, indicating it feeds supplemental DC battery capacity to a host Nexsys UPS rather than delivering conditioned AC to loads. Its topology is listed as Online (double-conversion), consistent with the Nexsys system architecture it extends.
The UPX-RLNK-1000R-2 is described as a '1000VA 120V UPS Rlnk Bank Control,' indicating it is a standalone UPS with integrated remote link (RLNK) power bank-switching capability. Its 36 VDC output voltage versus the UPX-EXPANRUN-OL10's 24 VDC output signals a different internal battery configuration. No topology label (online/line-interactive) is present in the provided specs for the UPX-RLNK-1000R-2, so a direct topology comparison cannot be made from supplied data alone.
For deployment: the UPX-EXPANRUN-OL10 requires a compatible host Nexsys UPS and cannot function independently. The UPX-RLNK-1000R-2 appears to function as a self-contained unit with bank-control features. Installers must confirm system compatibility before specifying the EXPANRUN unit.
How do the physical footprint, weight, and electrical specifications compare for rack planning and load calculations?
Both units occupy 2RU in a standard 19-inch rack and share a 16-inch (40.6 cm) depth, NEMA 5-15P plug, NEMA 5-15R receptacle, and a 6-foot (1.8 m) cord. Height is nearly identical: 3.5 in (8.9 cm) for the UPX-EXPANRUN-OL10 versus 3.46 in (8.8 cm) for the UPX-RLNK-1000R-2—a negligible 0.04-inch difference.
Weight is a meaningful rack-loading differentiator. The UPX-EXPANRUN-OL10 weighs 41.4 lbs (18.8 kg). The UPX-RLNK-1000R-2 is heavier at 44.1 lbs (20 kg) unit weight, with a shipping weight of 52 lbs (23.6 kg) noted. The EXPANRUN unit's shipping weight is not specified.
On the AC electrical side, the UPX-EXPANRUN-OL10 provides more detail: 15A input, 120 VAC input, 110–127 VAC AC output range, and mounting depth range of 18–32 inches. The UPX-RLNK-1000R-2 specs list only 120 VAC input and 6-foot cord; no AC amperage, output voltage range, or mounting depth range are provided in the supplied data. Both carry a 1000VA rating.
What do the compliance certifications, warranty, and management features tell us about long-term supportability and integration?
The UPX-EXPANRUN-OL10 carries FCC (listed as CSA field), RoHS (listed as REACH field), and Patents (listed as TUV field) compliance markers. Its battery warranty is stated as 3 years (listed in a '2 Years Battery' field, with the value '3 years'—buyers should verify the exact warranty term with Middle Atlantic documentation). Neither unit is TAA compliant per the provided specs.
The UPX-RLNK-1000R-2 has no compliance certifications or warranty data present in the supplied specifications. Installers requiring FCC, RoHS, or specific warranty commitments cannot confirm these attributes from the provided data for the RLNK unit and must consult the manufacturer datasheet directly.
From a management standpoint, the UPX-RLNK-1000R-2's 'bank control' designation in its name and description implies remote power switching or outlet-level control via Middle Atlantic's RLNK ecosystem—a significant integration feature for AV/IT rack managers. The UPX-EXPANRUN-OL10 carries no management feature references in its specs; its role is purely runtime extension. No network interface, SNMP, or software compatibility data is provided for either unit in the supplied specs.
Which should you choose: the UPX-EXPANRUN-OL10 or the RLNK-1000R-2?
Our take: The UPX-RLNK-1000R-2 is the stronger choice when you need a self-contained 1000VA UPS with integrated remote bank-switching control in a single 2RU footprint. The UPX-EXPANRUN-OL10 is not a standalone UPS—it is a runtime expansion accessory that depends on a host Nexsys UPS, making it the correct specification only when extending battery runtime on an existing compatible system. Key spec deltas: the RLNK unit is 2.7 lbs heavier (44.1 vs. 41.4 lbs), its DC output voltage is 36 VDC versus 24 VDC on the EXPANRUN, and the EXPANRUN carries documented FCC and RoHS compliance while the RLNK's certifications are absent from the provided specs. Platform qualifier: specify the UPX-EXPANRUN-OL10 only as part of a Nexsys system expansion; for any new standalone installation requiring bank-level power control, specify the UPX-RLNK-1000R-2 and confirm certification requirements directly with Middle Atlantic.

Frequently Asked Questions
Which should you choose: the UPX-EXPANRUN-OL10 or the RLNK-1000R-2?
The UPX-RLNK-1000R-2 is the stronger choice when you need a self-contained 1000VA UPS with integrated remote bank-switching control in a single 2RU footprint. The UPX-EXPANRUN-OL10 is not a standalone UPS—it is a runtime expansion accessory that depends on a host Nexsys UPS, making it the correct specification only when extending battery runtime on an existing compatible system. Key spec deltas: the RLNK unit is 2.7 lbs heavier (44.1 vs. 41.4 lbs), its DC output voltage is 36 VDC versus 24 VDC on the EXPANRUN, and the EXPANRUN carries documented FCC and RoHS compliance while the RLNK's certifications are absent from the provided specs. Platform qualifier: specify the UPX-EXPANRUN-OL10 only as part of a Nexsys system expansion; for any new standalone installation requiring bank-level power control, specify the UPX-RLNK-1000R-2 and confirm certification requirements directly with Middle Atlantic.
Can I use the UPX-EXPANRUN-OL10 as a standalone UPS without any other equipment?
No. Based on the provided specifications, the UPX-EXPANRUN-OL10 is a run-time expansion unit designed to add battery capacity to an existing compatible Nexsys UPS host. It cannot independently condition or supply AC power to loads. You must have a compatible Nexsys UPS already installed before adding this unit.
Is the UPX-RLNK-1000R-2 or the UPX-EXPANRUN-OL10 better for remote power management of individual outlet banks?
The UPX-RLNK-1000R-2 is the appropriate choice. Its name and description reference 'Rlnk Bank Control,' indicating integration with Middle Atlantic's remote link power management platform for outlet-level switching. The UPX-EXPANRUN-OL10 has no management or bank-control features listed in its specifications—it is solely a runtime extension unit.
Do both units fit in the same rack space and use the same power connections?
Yes, on footprint and connections they are essentially identical per the provided specs: both are 2RU, 19 inches wide, 16 inches deep, use a NEMA 5-15P plug and NEMA 5-15R receptacle, accept 120 VAC input, and include a 6-foot cord. The UPX-RLNK-1000R-2 is 2.7 lbs heavier (44.1 vs. 41.4 lbs), which should be accounted for in rack weight calculations.
