Middle Atlantic UPX-RLNK-OL1500R-2 Nexsys 1500VA Online Double-Conversion Rack UPS with Bank Outlet Control

The Middle Atlantic UPX-RLNK-OL1500R-2 is a 1500VA / 1350W online double-conversion UPS engineered for AV racks, security head-end closets, and IT infrastructure rooms where zero transfer time and remote outlet management are non-negotiable. Unlike line-interactive or standby UPS units that switch to battery on a fault, online double-conversion continuously regenerates clean AC output from the inverter — utility power never reaches your equipment directly. For NVR stacks, managed switches, or access control servers where a momentary brownout can corrupt a database or drop a camera feed, this topology is the correct starting point.

Key Features

• Online Double-Conversion Topology: The inverter drives the load 100% of the time, so there is no transfer gap when utility power fails or surges. Equipment connected to the UPX-RLNK-OL1500R-2 sees a regulated 110–127 VAC sine wave regardless of what the grid is doing — critical for NVRs and servers that trip on micro-interruptions.
• 1500VA / 1350W Capacity: At a 0.9 power factor, 1350W of real load capacity gives you enough headroom for a mid-density security rack — a 16-channel NVR, a PoE switch, a managed firewall, and several storage drives without pushing the unit past 80% load, which is the safe operating ceiling for sustained runtime.
• Bank-Controlled Outlet Management: All 8 NEMA 5-15R receptacles are grouped into switchable banks. With the included network card, you can remotely power-cycle individual outlet banks — restart a frozen NVR without touching the rack, sequence startup to avoid inrush stacking, or shed non-critical loads to extend battery runtime during an extended outage.
• Network Card Included: The UPX-RLNK-OL1500R-2 ships with a network management card pre-installed. Remote monitoring, outlet control, and UPS status alerts are available over IP without an additional accessory purchase — a meaningful cost and installation difference versus UPS models that treat network management as an upsell.
• Energy Star 2.0 Certified: Online double-conversion units typically run less efficiently than line-interactive designs, but the Energy Star 2.0 rating means this unit has cleared efficiency benchmarks that reduce heat output and operating cost in always-on deployments. In a 24/7 security operations environment, efficiency losses compound over thousands of hours.
• 2U Rackmount Form Factor (19 in W × 3.5 in H × 16 in D): Fits standard 19-inch EIA racks with a 16-inch depth footprint, accommodating rack cabinets with a minimum usable depth of 22 inches and maximum of 34 inches. Four mounting points secure the chassis — relevant in mobile or vibration-prone environments. At 44.7 lbs, plan for two-person installation.
• cTUVus Safety Listed: The cTUVus mark covers both US (UL) and Canadian (CSA) safety requirements under a single third-party listing. For commercial installations that require AHJ sign-off or insurance compliance, this covers both markets without sourcing a separate CSA-listed unit.
• REACH / FCC Compliance: REACH compliance confirms the unit has been evaluated against EU chemical substance restrictions — relevant for integrators working on government, healthcare, or environmentally sensitive facilities with material compliance requirements.
• NEMA 5-15P Input Plug with 6 ft Cord: The standard 15-amp NEMA 5-15P plug connects to any standard US outlet or PDU with a 5-15R receptacle. The 6-foot cord gives reasonable slack for most rack-to-PDU runs without excess cable management overhead.
• Operating Temperature Range 32°–104°F (0°–40°C): Standard commercial operating range. Adequate for conditioned data rooms and equipment closets. Not suitable for unconditioned outdoor enclosures or industrial environments that regularly exceed 104°F — factor this in for warm-climate wiring closets without dedicated cooling.

Integration and Compatibility

The UPX-RLNK-OL1500R-2 is designed for integration into Middle Atlantic rack systems and is equally at home in any standard 19-inch EIA rack cabinet. The included network card enables SNMP-based monitoring, meaning it can report UPS status into most network management platforms and enterprise monitoring systems without additional middleware. For security integrators building NVR-based surveillance systems or structured rack deployments, bank outlet control allows logical grouping — for example, placing all camera-side PoE switches on one bank and recording servers on another, so a power-cycle command doesn't inadvertently restart both simultaneously.

The 8 NEMA 5-15R receptacles support standard IEC or NEMA loads up to 15 amps total input. If your rack load exceeds 1350W or includes high-draw servers requiring 20-amp or C13/C19 receptacles, evaluate a higher-capacity model in the Nexsys line. For rack power distribution planning, consider pairing this UPS with a separate PDU downstream to expand receptacle count while keeping the UPS as the conditioning and backup stage. Refer to a UPS selection guide to verify runtime estimates against your specific load profile before specifying this unit.

Frequently Asked Questions

Q: What is the difference between the online double-conversion topology in the UPX-RLNK-OL1500R-2 and a line-interactive UPS?

A: In an online double-conversion unit like the UPX-RLNK-OL1500R-2, the inverter is always active and always powering the load — utility power is continuously converted to DC and back to AC. There is zero transfer time on power loss. A line-interactive UPS passes utility power through directly and only switches to battery when voltage goes out of range, introducing a brief transfer gap (typically 2–8 ms) that can affect sensitive electronics.

Q: Does the UPX-RLNK-OL1500R-2 include a network management card or is it an optional add-on?

A: The network card is included in the box — it is not an optional accessory for this model. The unit ships network-enabled with remote outlet bank control and UPS monitoring accessible over IP.

Q: How many outlets does the UPX-RLNK-OL1500R-2 provide and what receptacle type are they?

A: The unit has 8 NEMA 5-15R receptacles organized into switchable banks for remote control. The input plug is NEMA 5-15P on a 6-foot cord drawing up to 15 amps.

Q: What rack depth is required to install the UPX-RLNK-OL1500R-2?

A: The unit requires a minimum rack mounting depth of 22 inches and supports up to 34 inches maximum mounting depth. The chassis itself is 16 inches deep and 3.5 inches tall (2U) in a standard 19-inch wide form factor with 4 mounting points.

Q: Is the UPX-RLNK-OL1500R-2 TAA compliant for government procurement?

A: No — the UPX-RLNK-OL1500R-2 is explicitly listed as not TAA compliant. If your project requires TAA compliance for federal or GSA purchasing, you will need to evaluate an alternate model.

Q: What safety and efficiency certifications does the UPX-RLNK-OL1500R-2 carry?

A: The unit holds a cTUVus listing (covering both US UL and Canadian CSA safety requirements) and is Energy Star 2.0 certified for efficiency. It also carries REACH compliance for chemical substance requirements.

The UPX-RLNK-OL1500R-2 is one of the few 1500VA rack UPS options that ships with an active network card and bank-level outlet control at this price tier — for security integrators building remotely managed head-end racks, that combination eliminates a common service-call scenario where a frozen NVR or stuck recorder requires a site visit just to power-cycle one device. The 1350W real power output at a 0.9 power factor is what actually matters for load planning, not the VA rating alone.

Technical Highlights:

• Online Double-Conversion: Zero-transfer-time topology means your NVR, managed switch, or access control server never sees a gap between utility and battery — unlike line-interactive designs that take 2–8 ms to switch, which is enough to reboot some embedded systems.
• Bank Outlet Control via Network Card: With 8 NEMA 5-15R outlets in switchable banks and the included network card, you can issue a remote power-cycle to a specific bank without touching the rack — sequence restarts, shed loads to extend runtime, or automate recovery scripts via SNMP.
• Energy Star 2.0 on an Online Topology: Online double-conversion units are inherently less efficient than line-interactive designs because the inverter runs continuously. The Energy Star 2.0 rating means this unit has cleared efficiency thresholds that reduce both heat load in the rack and long-term operating cost — worth factoring for always-on 24/7 deployments.

Deployment Considerations:

• At 44.7 lbs in a 2U chassis, plan for two-person installation — slide rails or a lift assist is advisable in tall racks. Verify your rack cabinet provides at least 22 inches of usable mounting depth before ordering.
• The NEMA 5-15P input plug is rated for 15 amps total — with 1350W of UPS capacity, you are near the practical limit of a single 15A branch circuit at continuous load. Size your connected equipment accordingly and do not daisy-chain this UPS from a PDU that is already loaded near its circuit breaker threshold. Also note: TAA compliance is absent, which disqualifies this unit from federal procurement vehicles requiring TAA.

This unit is well-suited for mid-density commercial security racks in managed service or enterprise campus deployments where remote outlet control reduces truck rolls and online topology protects recording continuity during utility instability — a physical security operations center or multi-NVR closet serving a retail portfolio is a natural fit.
