Middle Atlantic UPX-RLNK-OL2000R-8 Nexsys 2KVA Online Double-Conversion Rack UPS

Overview

The Middle Atlantic UPX-RLNK-OL2000R-8 is a 2000VA/1800W online double-conversion rack UPS built for AV, security, and IT infrastructure where clean, uninterrupted power is non-negotiable. Online double-conversion topology means your connected equipment never runs on raw utility power — every watt passes through a full AC-to-DC-to-AC conversion cycle continuously, not just during an outage. The result is zero transfer time on a utility failure, and complete isolation from line noise, surges, and frequency drift before they ever reach your gear. If you're powering network video recorders, managed switches, or access control servers in a rack environment, this is the topology to specify. The UPX-RLNK-OL2000R-8 occupies 2U (3.5 in tall) in a standard 19-inch rack and supports a mounting depth range of 22 to 34 inches — compatible with most mid-depth and full-depth two-post and four-post enclosures.

Key Features

• Online Double-Conversion Topology: Unlike line-interactive or standby UPS designs that switch to battery only on failure, the UPX-RLNK-OL2000R-8 runs through full double-conversion at all times. Transfer time to battery is zero milliseconds — critical for rack-mounted NVRs and servers that will lock up or reboot on even a brief power interruption.
• 2000VA / 1800W Capacity: At a 0.9 power factor, this unit delivers its full 1800W of real power — not a derated figure. That's enough headroom to carry a mid-density security rack: think a 16-channel NVR, a PoE switch, a managed firewall, and ancillary control hardware simultaneously. Size your load to 80% of capacity (1440W) for thermal and battery longevity.
• 8 Individually Controlled NEMA 5-20R Outlets: Per-outlet switching lets you sequence power-up order (critical for avoiding inrush stacking on boot), remotely reboot a locked device without a site visit, and shed non-critical loads to extend battery runtime during an outage. For integrators managing distributed sites remotely, this is the operational differentiator versus a basic PDU. Matches NEMA 5-20P plug standard.
• Network Card Included: The UPX-RLNK-OL2000R-8 ships with a network card already installed — no separate card purchase required. This enables SNMP monitoring, remote outlet control, and automated graceful shutdown of connected servers before battery depletion. Check compatibility with your NMS or VMS platform before deployment.
• Energy Star 2.0 Certified: Online double-conversion units historically carry efficiency penalties. Energy Star 2.0 qualification indicates this unit meets DOE efficiency thresholds for always-on conversion — a real factor in 24/7 security operations centers where the UPS runs continuously for years.
• cTUVus Safety Listed: Carries both US and Canadian safety certification under the cTUVus mark, covering commercial installation requirements across North American jurisdictions. Relevant if your project requires AHJ sign-off or insurance compliance documentation.
• Rack Form Factor — 19 in Wide, 3.5 in Tall, 16 in Deep: Standard EIA-310 19-inch width with a 16-inch chassis depth leaves cable management and airflow space in most rack configurations. The 45.2 lb unit weight (shipping weight 52.71 lbs) requires a two-person lift and a shelf or proper rack rail mount — plan accordingly during staging.
• 110–127 VAC Output at 20 Amps: Regulated output voltage stays within a tight band regardless of input sag or surge — the inverter holds the output rail stable. The 20A circuit on a NEMA 5-20P plug requires a 20A dedicated circuit at the panel; verify your rack's circuit capacity before installation. The 6 ft (1.8 m) power cord is workable for most rack positions but may require an extension in deeper installations.
• Operating Temperature 32°–104°F (0°–40°C): Standard commercial temperature range. This unit is not rated for unconditioned environments — if your IDF closet or remote enclosure lacks climate control and regularly exceeds 104°F ambient, factor in derating or alternative solutions.
• REACH Compliance (FCC): Confirms compliance with EU REACH chemical substance regulations — relevant for international deployments or government projects with materials compliance requirements.

Integration & Compatibility

The included network card supports remote management via SNMP, making the UPX-RLNK-OL2000R-8 straightforward to integrate into enterprise NMS environments. Individual outlet control is accessible via the network interface, enabling remote power cycling of connected IP cameras, NVRs, and network switches without dispatching a technician. The NEMA 5-20R receptacle format is standard across commercial IT and AV equipment — no adapters required for most rack-mounted security and networking hardware. For PoE switches powering camera runs, the ability to gracefully reboot the switch via the UPS network card (rather than hard-cycling it) preserves managed switch configuration and avoids spanning-tree reconvergence delays. Review your VMS and NMS vendor documentation for supported UPS shutdown agents compatible with this unit's network management interface.

This UPS is not TAA compliant — federal procurement projects subject to the Trade Agreements Act must specify an alternate model.

Frequently Asked Questions

Q: What is the difference between the online double-conversion topology on the UPX-RLNK-OL2000R-8 and a line-interactive UPS?

A: A line-interactive UPS uses AVR to correct minor voltage fluctuations but still switches to battery during a true outage — transfer time is typically 4–12 milliseconds. The UPX-RLNK-OL2000R-8 uses online double-conversion: all power runs through an AC-DC-AC inverter continuously, so transfer time on outage is zero milliseconds. Load equipment is always running from the inverter, fully isolated from utility line noise and sags.

Q: Is the UPX-RLNK-OL2000R-8 TAA compliant for federal or government projects?

A: No. The UPX-RLNK-OL2000R-8 is not TAA compliant. Federal procurement projects subject to the Trade Agreements Act requirements should consult the Middle Atlantic product line for a TAA-compliant alternative.

Q: Does the UPX-RLNK-OL2000R-8 include a network management card, or is that an add-on?

A: The network card is included — it ships installed in the unit. This enables SNMP-based monitoring, remote outlet control, and automated graceful server shutdown without an additional card purchase.

Q: What plug and circuit type does the UPX-RLNK-OL2000R-8 require?

A: It uses a NEMA 5-20P plug and requires a dedicated 20-amp circuit. Standard 15-amp circuits are not compatible. Verify your rack's electrical circuit capacity before installation.

Q: How many rack units does the UPX-RLNK-OL2000R-8 occupy, and what rack depth is required?

A: The unit is 3.5 inches tall (2U) and 16 inches deep. It supports rack mounting depths from 22 to 34 inches, covering most standard two-post and four-post rack enclosures.

Q: Can individual outlets on the UPX-RLNK-OL2000R-8 be controlled independently?

A: Yes. All 8 NEMA 5-20R outlets support individual switching and control via the included network card. This allows per-device power sequencing on startup, remote reboot of locked equipment, and selective load shedding during battery operation to extend runtime for priority devices.

The UPX-RLNK-OL2000R-8 is one of the few 2U rack UPS options that ships with the network card already installed and gives you per-outlet switching on all 8 NEMA 5-20R receptacles — that combination matters when you're managing a security rack remotely. At 2000VA/1800W with a genuine 0.9 power factor, the published wattage is the real wattage, which is not always the case in this product category.

Technical Highlights:

• Online Double-Conversion: Zero-millisecond transfer time — NVRs and servers never see a power interruption. Line-interactive alternatives introduce a 4–12ms gap that can trigger unexpected reboots on sensitive equipment.
• 1800W Real Power at 2000VA: The 0.9 power factor means no hidden derating. Plan loads to 80% (1440W) for battery longevity and thermal headroom in a sealed rack enclosure.
• 8 Individually Controlled Outlets: Remote power cycling via the included network card — sequence boot order to avoid inrush stacking, reboot a locked NVR without a truck roll, and shed non-essential loads to extend runtime for your highest-priority devices during an outage.

Deployment Considerations:

• The 45.2 lb unit weight requires a two-person lift and dedicated rack rail support — do not attempt to shelf-mount this unit without verifying shelf weight rating. Plan the physical install during rack staging, not after the rack is in the wall.
• The NEMA 5-20P plug requires a dedicated 20A circuit at the panel. If your rack position only has a 15A circuit today, that's an electrical rough-in change — verify before ordering. Also confirm your NMS supports the SNMP agent on this unit's network card before relying on automated graceful shutdown.

This unit is the right call for a mid-density physical security rack — 16-channel NVR, managed PoE switch, access control server — in a commercial facility where a site visit to reboot equipment costs real money and any outage creates a compliance gap. It is not the right pick for federal procurement due to the lack of TAA compliance.
