Middle Atlantic UPX-RLNK-OL1500R-8 Nexsys 1500VA Online Rack UPS with Individual Outlet Control

Overview

The Middle Atlantic UPX-RLNK-OL1500R-8 is a 1500VA / 1350W double-conversion online UPS designed for 2U rack deployment in AV systems racks, security equipment rooms, and network closets where clean, uninterrupted power is non-negotiable. Unlike line-interactive designs that only switch to battery on sag or surge, the online topology runs all connected loads off the inverter continuously — utility power never touches your equipment directly. That means zero transfer time during outages, complete galvanic isolation from line noise, and consistent 110–127 VAC output regardless of what the utility is doing upstream. If you're protecting NVRs, access control servers, or managed switches in a mixed rack, that topology distinction is the one spec that matters most.

Key Features

• Online Double-Conversion Topology: The inverter is always in the circuit — there is no transfer delay during a power failure. For surveillance NVRs mid-write or access control panels mid-transaction, that zero-millisecond switchover prevents data corruption and eliminates the nuisance alarms that a 4–8 ms line-interactive transfer can trigger on sensitive equipment.
• 1500VA / 1350W Capacity: At a 0.9 power factor, 1350W of real power delivery gives you meaningful headroom for a fully populated rack. A typical 4K NVR drawing 80W plus four PoE switches at 150W each leaves you 670W of margin for additional gear or growth — plan your load budget before you buy, but this unit handles mid-size security rack loads without de-rating concerns.
• 8 Individually Controlled Outlets (NEMA 5-15R): Each outlet can be switched on, off, or power-cycled independently over the network. That means you can reboot a hung access control panel or a frozen IP intercom gateway without walking to the rack or cycling everything else in the bay — critical in remote or unstaffed equipment rooms. The 15A circuit across the 8 outlets aligns with the NEMA 5-15P plug on a standard 15A branch circuit.
• Network Card Included: The UPS ships with a network card already installed. You get remote monitoring, outlet control, and shutdown scripting without a separate accessory purchase. For integrators managing multiple sites, this means each unit is addressable from a central NMS the day it goes in — no retrofit required.
• 2U Rack Form Factor, 19 in Wide: At 3.5 in tall and 19 in wide, the UPX-RLNK-OL1500R-8 drops into any standard 19-inch rack. Minimum mounting depth is 22 in, maximum is 34 in, and the unit itself runs 16 in deep at 44.7 lbs — confirm your rail depth and weight rating before install. The 4-point mounting keeps the chassis stable under the battery mass.
• Energy Star 2.0 / cTUVus Listed: Energy Star 2.0 certification means the UPS meets efficiency thresholds that reduce heat load in the rack — relevant in closets without dedicated HVAC. cTUVus listing confirms it has passed both US and Canadian safety standards, which matters for installations requiring AHJ signoff or insurance compliance.
• Operating Range 32°–104°F (0°–40°C): The rated thermal envelope covers conditioned equipment rooms and most indoor commercial spaces. It does not cover unconditioned spaces — a warehouse or parking structure equipment cabinet that sees summer heat above 104°F will shorten battery life and may void the warranty. Size your cooling accordingly if this is going into a tight telecom cabinet.
• 6 ft Cord, NEMA 5-15P Plug: The 6 ft power cord gives you enough reach for most rack-to-PDU or rack-to-wall configurations without an extension. The standard NEMA 5-15P plug means no special receptacle — plug it into any 15A commercial outlet.

Integration & Compatibility

The network-enabled outlet control on the UPX-RLNK-OL1500R-8 is designed to integrate with standard SNMP-based network management platforms and UPS management software. The included network card provides the interface for scheduled outlet sequencing, load monitoring, and graceful shutdown scripting for connected servers or NVRs. For rack UPS deployments in security or AV infrastructure, the individual outlet control pairs well with IP-addressable PDUs for full per-device power visibility. The NEMA 5-15R receptacles accept standard North American plugs — no IEC adapter required for typical North American security hardware. Review your power protection planning to confirm load requirements before spec-ing this unit into a high-density PoE switch rack, where 15A budgets fill quickly. Pair with a compatible Middle Atlantic rack enclosure sized for the 22–34 in mounting depth requirement.

Frequently Asked Questions

Q: What is the difference between this online topology UPS and a line-interactive UPS for rack security equipment?

A: An online (double-conversion) UPS like the UPX-RLNK-OL1500R-8 continuously powers your equipment from its inverter — utility power charges the battery, but never passes directly to the load. There is zero transfer time during an outage. A line-interactive UPS passes utility power through and switches to battery only on failure, introducing a 4–8 ms transfer window that can cause sensitive equipment to reboot or trigger alarms. For NVRs, access control servers, and managed switches, the online topology is the more reliable choice.

Q: Does the UPX-RLNK-OL1500R-8 include a network card, or is it sold separately?

A: The network card is included with the unit. You can remotely monitor, control, and schedule each of the 8 outlets individually over the network from the day of installation without any additional accessory purchase.

Q: Is the UPX-RLNK-OL1500R-8 TAA compliant?

A: No. Per manufacturer specifications, this unit is not TAA compliant. If your project requires TAA compliance for government or federal procurement, you will need to select an alternate model.

Q: What rack depth is required to install the UPX-RLNK-OL1500R-8?

A: The unit requires a minimum rail-to-rail mounting depth of 22 inches and supports up to 34 inches. The chassis itself is 16 inches deep. Verify your rack's usable depth before ordering — undersized enclosures are the most common install issue with this unit given its 44.7 lb weight.

Q: How many outlets does the UPX-RLNK-OL1500R-8 provide, and can they be controlled independently?

A: It provides 8 NEMA 5-15R outlets with individual control. Each outlet can be switched, cycled, or scheduled independently via the included network card — useful for remotely rebooting a single hung device without interrupting the rest of the rack.

Q: What certifications does the UPX-RLNK-OL1500R-8 carry?

A: The unit is cTUVus listed (covering both US and Canadian safety standards), Energy Star 2.0 certified, and carries REACH compliance. It is not TAA compliant per manufacturer data.

The spec I always point to first on the UPX-RLNK-OL1500R-8 is the online double-conversion topology — not the VA rating, not the outlet count. When you're protecting an NVR recording 16 channels of 4K or an access control server managing door credentials for a 300-person facility, that zero-transfer-time distinction is the difference between a clean failover and a 3 a.m. support call from a customer whose cameras dropped mid-write.

Technical Highlights:

• 1350W Real Power at 0.9 PF: The 1500VA rating translates to 1350W of actual usable wattage — more honest headroom than units that advertise VA without specifying power factor. A mid-size security rack running an NVR, two managed PoE switches, and an access panel typically lands in the 400–600W range, leaving meaningful reserve for runtime extension.
• 8 Individually Switched NEMA 5-15R Outlets: Outlet-level remote control via the included network card means you can power-cycle a frozen IP intercom or access controller from a browser without touching anything else in the rack. On multi-site deployments, this capability alone eliminates truck rolls for simple device hangs.
• Energy Star 2.0 Efficiency: Double-conversion designs historically run warmer than line-interactive units. The Energy Star 2.0 rating indicates the inverter/rectifier chain meets efficiency thresholds that keep heat addition to the rack in check — worth noting if you're installing into a tight equipment closet without dedicated cooling.

Deployment Considerations:

• Confirm your rack has at least 22 inches of usable rail-to-rail depth before you order — the 16-inch chassis plus cable management at the rear eats space quickly, and at 44.7 lbs this is not a unit you want to discover won't fit during install.
• The NEMA 5-15P plug limits you to a standard 15A branch circuit; if your rack PDU is wired for 20A (NEMA 5-20R), you'll need a pigtail adapter or to re-evaluate the branch circuit — don't exceed the 15A cord rating regardless of what the PDU can deliver.

This unit is a strong fit for unmanned remote security equipment rooms — a branch office server closet or a parking structure head-end cabinet — where the combination of zero-transfer online power and network-based outlet control lets a central NOC handle routine device restarts without dispatching a technician.
