Middle Atlantic UPX-OL1000R-2 Nexsys 1KVA Online Double-Conversion Rack UPS

Overview

The Middle Atlantic UPX-OL1000R-2 is a 1000VA/1000W true online double-conversion UPS designed for AV and security rack systems where a split-second transfer gap is unacceptable. Unlike standby or line-interactive designs that switch to battery only after detecting a fault, a true online topology continuously powers connected loads through the inverter — meaning zero transfer time and continuous voltage regulation regardless of what the utility line throws at it. For network video recorders, managed switches, and access control servers running 24/7, that distinction matters.

Key Features

• True Online (Double-Conversion) Topology: Utility power is continuously rectified to DC and re-inverted to clean AC — the load never touches raw mains. Voltage spikes, brownouts, and frequency deviations are absorbed without any transfer switching. If your NVR or VMS server has experienced unexplained reboots or corrupted recordings during utility events, this is the topology that eliminates the root cause.
• 1000VA / 1000W at Unity Power Factor: VA and watt ratings are identical here, which means no derating calculation required when sizing for resistive and mixed loads. Eight NEMA 5-15R receptacles can collectively draw up to 15A — plan your connected load budget at no more than 80% (12A) for thermal headroom and NEC compliance on continuous loads.
• 8-Outlet Bank Control: The outlet control type is bank-based, allowing groups of outlets to be sequenced on or off independently. This is practical for rack builds where you want NVRs and switches to power up before cameras, or where you need to cycle a locked-up encoder without cutting the entire rack. Check outlet grouping layout against your specific load-sequencing requirements before specifying.
• Network-Enabled Management (No Card Included): The UPX-OL1000R-2 is network-enabled but ships without a network card. If remote monitoring, SNMP integration with a DCIM or BMS platform, or scheduled outlet actions are on the requirements list, budget for the separately purchased network management card. Without it, you get local LCD and USB management only.
• 2U Rack Form Factor, 19-Inch Width: At 19 in wide × 3.5 in tall (2U) × 16 in deep, this unit mounts in any standard EIA-310 rack. The mounting depth requirement is 22–34 in — verify your rack's usable depth before ordering. At 33.1 lbs, factor in rack weight budgets, particularly in wall-mount or shallow-depth enclosures.
• NEMA 5-15 Input and Output: Input is a standard NEMA 5-15P plug on a 6 ft cord — connects directly to a 15A wall circuit or PDU without adapters. Output receptacles are eight NEMA 5-15R, which matches most 1U servers, NVRs, and network appliances without adapter pigtails. If your load devices use NEMA 5-20R or IEC C13, plan for outlet adapters accordingly.
• Energy Star 2.0 / cTUVus Listed: Energy Star 2.0 certification reflects efficiency performance that reduces operating costs on always-on deployments. The cTUVus listing (CSA) covers both US and Canadian safety requirements — relevant for multi-country deployments or facilities with strict procurement standards. REACH compliance is noted; this unit is not TAA compliant, which disqualifies it from federal procurement or TAA-restricted contracts.
• Operating Range 32°–104°F (0°–40°C): Standard commercial temperature range. Rack enclosures with poor airflow can push ambient temps above 40°C — verify rack thermal management if this UPS is installed in a sealed or outdoor-rated enclosure. Battery performance degrades near the high end of the operating range; high-temperature environments shorten battery service life.

Integration and Compatibility

The UPX-OL1000R-2 fits within a rack UPS strategy alongside Middle Atlantic rack enclosures that accept standard EIA-310 components. The 22–34 in mounting depth range covers most 2-post and 4-post open-frame racks as well as mid-depth enclosed racks. For PoE switch and NVR combinations that draw 400–800W continuously, this 1000W unit provides roughly 10–20 minutes of runtime at full load depending on battery condition — size runtime expectations accordingly or pair with an extended battery module if runtime beyond that is required. The bank control outlet grouping supports power sequencing logic that integrates with supported network management cards for automated load shedding. If your AV or security rack uses a Legrand/Middle Atlantic rack enclosure, this UPS mounts natively with four mounting points and no additional adapter rails. Consult a rack and enclosure guide to confirm depth compatibility before finalizing your rack layout.

Frequently Asked Questions

Q: What is the difference between the online topology in the UPX-OL1000R-2 and a line-interactive UPS?

A: A line-interactive UPS switches to battery only when it detects an out-of-range utility condition, introducing a brief transfer time (typically 2–10 ms). The UPX-OL1000R-2 uses a true online double-conversion design where the load runs continuously from the inverter — transfer time is zero because there is no switching event. This also means the output voltage is continuously regulated and isolated from utility noise, which benefits sensitive electronics.

Q: Is the UPX-OL1000R-2 TAA compliant for federal or government procurement?

A: No. The UPX-OL1000R-2 is explicitly listed as TAA Non-Compliant and cannot be used on federal contracts or procurements requiring TAA compliance. Verify contract requirements before specifying this model on government projects.

Q: Does the UPX-OL1000R-2 include a network management card?

A: No. The unit is network-enabled but ships without a network card installed. Remote SNMP monitoring, network-based outlet control, and integration with building management or DCIM systems require a separately purchased network management card compatible with the Nexsys UPS platform.

Q: What rack depth is required to install the UPX-OL1000R-2?

A: The mounting depth range is 22 in minimum to 34 in maximum. The unit body is 16 in deep. Confirm your rack's usable rail-to-rail depth falls within this range before ordering. Racks shallower than 22 in or deeper than 34 in will require alternative mounting solutions.

Q: What certifications does the UPX-OL1000R-2 carry?

A: The UPX-OL1000R-2 is cTUVus listed (covering both US and Canadian safety requirements), Energy Star 2.0 certified, and REACH compliant. It is not TAA compliant.

Q: Can the UPX-OL1000R-2 power devices with NEMA 5-20 or IEC C13 plugs?

A: The eight output receptacles are NEMA 5-15R. Devices requiring NEMA 5-20R or IEC C13 connections will need compatible outlet adapters. NEMA 5-15P plugs (most 1U servers, switches, and NVRs) connect directly without adapters.

The spec I always point integrators to first on the UPX-OL1000R-2 is the topology — true online double-conversion at 1000W means your NVR or access control server is never touching raw utility power. The inverter is the power source, full stop. That distinction eliminates the transfer-time conversation entirely and delivers clean, regulated 110–127 VAC output continuously, not just during an event.

Technical Highlights:

• Unity Power Factor (1000VA = 1000W): No derating math — what you see is what you get. Size your connected loads to 80% (800W / 12A) for NEC compliance on continuous loads and you have clean headroom.
• Bank-Controlled 8 Outlets: Group-level switching lets you sequence NVRs and switches on before cameras, or cycle a locked encoder without dropping the entire rack. This is the outlet control feature that matters most in a security rack with mixed load priorities.
• Energy Star 2.0 + cTUVus: Efficiency certification reduces operating costs on a device that runs 24/7/365. cTUVus covers US and Canadian safety requirements in a single listing — one SKU serves both markets without re-certification headaches.

Deployment Considerations:

• Mounting depth range is 22–34 in — measure your rack's usable depth before specifying. The unit body is 16 in, but the rails need to land within that 22–34 in window. Wall-mount shallow racks under 22 in are a hard no.
• No network card is included. If your customer expects SNMP integration or automated load shedding via software, that card needs to be on the BOM separately. Missing it at install is a common field surprise on this platform.

This unit earns its place in a commercial security rack — specifically a mid-size NVR-plus-switch stack where clean power, zero transfer time, and outlet-level sequencing are requirements, not nice-to-haves. It is not the right call for federal procurement (TAA non-compliant) or any rack that runs persistently above 40°C ambient without active cooling.
