Middle Atlantic Nexsys 1000VA UPS RUN Time Unit - UPX-EXPANRUN-OL10

Middle Atlantic UPX-EXPANRUN-OL10 Nexsys 1000VA Online UPS Run Time Expansion Unit

The Middle Atlantic UPX-EXPANRUN-OL10 is a 1000VA rack-mount run time expansion unit built for the Nexsys Online UPS platform — designed to extend battery backup duration on security control rooms, AV infrastructure racks, and network equipment closets where a brief power interruption is not an option. At 2RU and 41.4 lbs, this is a dedicated battery expansion chassis, not a standalone UPS; it pairs with a compatible Nexsys online UPS base unit to add capacity without replacing your existing investment.

Overview

Online (double-conversion) topology means incoming AC is continuously converted to DC and back to clean AC — your downstream equipment never draws from raw utility power. Voltage spikes, brownouts, and frequency variations are all isolated before they reach the load. For security deployments running NVRs, access control servers, or VoIP infrastructure, this matters more than a simple standby UPS that only switches over after detecting a fault. The UPX-EXPANRUN-OL10 extends the runtime of an existing Nexsys online UPS system within a standard 19-inch rack, keeping that continuous-conversion protection in place for longer during an outage.

Key Features

• Online Double-Conversion Topology: Equipment draws from a continuously conditioned output — no switchover delay, no voltage sag during transfer. Critical for NVRs mid-write or access control panels that would fault on a momentary gap.
• 1000VA / 120VAC Input and Output: Handles 120VAC at up to 15 amps via a NEMA 5-15P plug, outputting 110–127VAC. Sized for a mid-density rack — enough capacity for core network gear, a primary NVR, and an access panel simultaneously.
• 24VDC Internal Bus: The 24VDC output connects to the Nexsys base unit's battery bus rather than directly to loads, so no additional DC cabling to end devices is required on the installer side.
• 2RU, 19-Inch Rack Form Factor: At 3.5 inches tall and 19 inches wide, it drops into any standard equipment rack. Mounting depth adjusts from 18 inches minimum to 32 inches maximum — compatible with shallow 18-inch telecom racks through deep 32-inch AV racks.
• 41.4 lb Weight — Plan Your Rail Load: This unit is heavy. At 41.4 lbs (18.8 kg), confirm your rack rail rating and shelf support before positioning. Center or lower rack placement is advisable to keep the center of gravity manageable.
• 6 ft NEMA 5-15P Cord: The 6-foot input cord reaches a standard in-rack PDU without extension. NEMA 5-15R receptacle type means standard 15A outlets — no special PDU required.
• 32°–104°F Operating Range: Rated for 0°–40°C ambient. Suitable for conditioned server rooms and typical equipment closets; not rated for unconditioned outdoor enclosures or hot attic installs where summer temps exceed 104°F.
• RoHS Compliant: Meets RoHS (Restriction of Hazardous Substances) requirements — relevant for installations in facilities with environmental compliance requirements or EU-bound deployments.
• FCC Listed: FCC compliance confirms the unit meets emissions standards, reducing interference risk with adjacent RF-sensitive equipment like wireless access points or alarm radio receivers in the same rack.
• 3-Year Battery: The included battery carries a 3-year coverage term — a useful planning benchmark for lifecycle replacement scheduling in managed facilities.

Integration and Compatibility

The Middle Atlantic Nexsys platform is a modular rack-mount UPS ecosystem; the UPX-EXPANRUN-OL10 is an expansion run time unit, not a standalone device. It requires a compatible Nexsys online UPS base unit to function. Verify compatibility with your specific base model before ordering — Middle Atlantic publishes compatibility matrices on their product pages. The 4-point rack mounting and 19-inch standard width integrate with any EIA-310-compliant rack. For deployments combining this unit with PoE network switches or NVR systems, factor the combined rail load carefully given the 41.4 lb weight. A structured power protection plan that includes surge suppression upstream of this unit will extend both the unit's and the load equipment's service life.

Frequently Asked Questions

Q: Is the UPX-EXPANRUN-OL10 a standalone UPS or does it require a base unit?

A: It is a run time expansion unit, not a standalone UPS. It must be paired with a compatible Middle Atlantic Nexsys online UPS base unit to operate. It does not provide UPS functionality on its own.

Q: What is the UPS topology on the UPX-EXPANRUN-OL10?

A: Online (double-conversion). The unit continuously converts incoming AC to DC and back to AC, so connected equipment always runs on conditioned power with zero transfer time during an outage.

Q: What rack space does the UPX-EXPANRUN-OL10 require?

A: It occupies 2 rack units (3.5 inches) in a standard 19-inch EIA rack. Mounting depth must be between 18 and 32 inches to accommodate the unit's 16-inch depth with proper support.

Q: Is the UPX-EXPANRUN-OL10 TAA compliant?

A: No. The unit is manufactured in China and is not TAA compliant. It is not eligible for federal government procurement under TAA-restricted contracts.

Q: What is the battery warranty on the UPX-EXPANRUN-OL10?

A: The battery carries a 3-year coverage term per the manufacturer's specifications for this unit.

Q: What input plug and outlet type does the UPX-EXPANRUN-OL10 use?

A: It uses a NEMA 5-15P input plug on a 6-foot cord and a NEMA 5-15R receptacle — standard 15-amp connections compatible with typical in-rack PDUs and wall outlets.

When I spec the UPX-EXPANRUN-OL10 into a security rack, the first thing I tell integrators is to verify their rack's rail load rating before anything else — 41.4 lbs in 2RU is denser than it looks, and I've seen mid-rack installs shift the balance point on lighter open-frame racks. This unit's role is extending runtime on an existing Nexsys online UPS, so get the base unit confirmed in your BOM first.

Technical Highlights:

• Online Topology: Double-conversion means zero transfer time — at 0ms, NVR write cycles and access control panels don't see the switchover at all. Standby UPS units typically switch in 4–10ms, which is enough to drop some embedded systems.
• 1000VA / 15A at 120VAC: Size this against your actual load. A typical security rack with an NVR, managed PoE switch, and access panel lands in the 400–700W range — the 1000VA capacity gives realistic headroom without over-speccing.
• 18–32 Inch Mounting Depth Range: The adjustable mounting depth (18 in minimum, 32 in maximum) covers nearly the full range of commercial rack depths. The unit itself is 16 inches deep, so verify your rack's usable interior depth against the 16-inch chassis before ordering.

Deployment Considerations:

• This is an expansion unit only — confirm the Nexsys base unit model compatibility before the order. The 24VDC output connects to the base unit's battery bus, not directly to any AC load equipment.
• Operating temperature tops out at 104°F (40°C). Equipment closets without active cooling can exceed this in summer months — if your closet runs hot, address cooling before adding battery mass that generates additional heat.

The UPX-EXPANRUN-OL10 (also searched as UPX EXPANRUN OL10) is a practical choice for physical security control rooms where online UPS protection is already deployed and the site requires extended runtime beyond what the base unit alone provides — think 24/7 monitoring stations, multi-door access control head-end racks, or any rack that cannot tolerate even a sub-cycle power interruption during a utility event.
