Middle Atlantic Select Series UPS Backup Power 2RU 1500VA - UPS-S1500R

Middle Atlantic UPS-S1500R Select Series 1500VA Rack-Mount UPS Backup Power

Overview

The Middle Atlantic UPS-S1500R is a 2RU, 1500VA rack-mount uninterruptible power supply built for AV and security system racks where a power interruption means lost recording time, dropped access control events, or a reboot cycle on critical edge hardware. At 1500VA with eight protected outlets and a 10 ft (3.1 m) power cord, the UPS-S1500R gives you enough capacity to cover a mid-density surveillance rack — NVR, PoE switch, and associated gear — through brief outages and safely shepherd devices through a controlled shutdown on longer ones. Its 2RU footprint fits cleanly into standard 19-inch rack infrastructure without consuming excessive rack real estate.

Middle Atlantic's full line of rack power and UPS systems is designed with AV and security integrators in mind, and the UPS-S1500R reflects that: adjustable mounting depth from 19 to 32 inches accommodates shallow wall enclosures as well as deep floor racks, and the two mounting points provide a secure, rattle-free installation. If you're speccing out a complete rack UPS solution for a surveillance or access control installation, this is the model to evaluate at the 1500VA tier.

Key Features

• 1500VA Capacity: Enough runtime headroom to keep a mid-density security rack — NVR, managed PoE switch, and edge appliances — online through transient outages and provide graceful shutdown time on extended failures. Size the connected load to roughly 60–70% of VA rating for meaningful runtime. See the PoE switch category for compatible switch options to pair with this UPS.
• Eight Protected Outlets: Eight outlets on a single 2RU unit means you can protect every device in a typical small-to-mid surveillance rack without daisy-chaining power strips. Consolidated outlet count reduces cable management complexity and single-point failure risk from unprotected strips.
• 2RU Rack Form Factor (19 in wide, 3.46 in tall): Standard 19-inch wide, 3.46-inch tall chassis drops into any EIA-310 compatible rack bay. Two rack units consumed per UPS — predictable when planning rack real estate for a multi-UPS deployment across multiple cabinets.
• Adjustable Mounting Depth — 19 to 32 in (48.3 to 81.3 cm): This is the spec that matters most for retrofit installs. Whether you're dropping into a shallow 2-post wall-mount rack or a full-depth 4-post floor cabinet, the UPS-S1500R's adjustable rail ears accommodate both without adapter kits. That 19-inch minimum depth makes it viable in compact enclosures where many UPS units won't fit.
• 10 ft (3.1 m) Corded Power Cord: A longer-than-standard 10 ft cord gives you flexibility to route to a dedicated 20A circuit without relying on an extension cord — critical for UPS installations where extension cords are a code and warranty concern.
• UL Listed: UL listing means the unit has been independently evaluated to recognized safety standards — a requirement for many commercial installations and a checkpoint some AHJs will ask about at commissioning. This is a verifiable certification, not a marketing claim.
• Basic Surge Protection: Built-in surge protection handles transient voltage spikes on the incoming line. Appropriate for typical commercial power environments; if the installation site is subject to frequent lightning or severe line disturbances, evaluate whether additional surge suppression upstream is warranted.
• 54 lb Shipping Weight: Plan rack loading and rack floor rating accordingly. At 54 lbs shipped, the installed unit will run approximately 45–50 lbs depending on battery configuration. Verify rack weight capacity before stacking multiple UPS units — this matters in wall-mount or ceiling-drop rack scenarios.

Integration and Compatibility

The UPS-S1500R integrates into standard 19-inch rack infrastructure and is well-suited for protecting network video recorders, managed switches, access control panels, and associated rack gear in commercial security deployments. The unit is TAA non-compliant, which matters if your project is subject to federal procurement rules — confirm requirements with the project owner before speccing this unit on government bids. The 8-outlet layout supports distributed load balancing across device types: assign battery-backed outlets to critical recording and network gear, and use any surge-only outlets (confirm with full product documentation) for less critical peripherals.

Frequently Asked Questions

Q: Is the Middle Atlantic UPS-S1500R TAA compliant?

A: No. The UPS-S1500R is explicitly TAA non-compliant per manufacturer documentation. If your project falls under federal procurement rules or GSA schedules requiring TAA compliance, this unit does not qualify — select a TAA-compliant alternative.

Q: What rack depths is the UPS-S1500R compatible with?

A: The UPS-S1500R supports adjustable mounting depth from 19 inches (minimum) up to 32 inches (maximum), covering the range from shallow 2-post wall racks to standard deep 4-post floor cabinets. No adapter kits are needed within that range.

Q: How many outlets does the UPS-S1500R provide?

A: Eight outlets total. This covers a typical mid-density security rack including an NVR, PoE switch, and associated edge devices from a single 2RU unit.

Q: What is the VA rating of the UPS-S1500R and how should I size my load?

A: The UPS-S1500R is rated at 1500VA. As a general sizing guideline, keep connected load at 60–70% of the VA rating (roughly 900–1050VA) to achieve meaningful runtime and avoid stressing the battery under sustained load.

Q: Is the UPS-S1500R UL listed?

A: Yes. The UPS-S1500R carries a UL listing, satisfying the independent safety evaluation requirement common in commercial AV and security installations.

Q: What is the power cord length on the UPS-S1500R?

A: The power cord is 10 feet (3.1 meters), which provides enough reach to connect to a dedicated circuit without requiring an extension cord in most rack closet and IT room configurations.

Ted Perry

The detail I flag first on the UPS-S1500R is the 19-to-32-inch adjustable mounting depth — that's genuinely useful in retrofit security installs where you're dropping into whatever rack the customer already has on-site. I've seen UPS units rejected at commissioning simply because the fixed rails didn't fit a shallow wall enclosure; this one handles both ends of that range without adapter hardware.

Technical Highlights:

• 1500VA / 8 Outlets: Right-sized for a single-rack NVR + PoE switch combination. Keep your connected load at 900–1050VA (60–70% of rating) and you'll have meaningful runtime rather than a hard cutoff at the first blink.
• 2RU at 3.46 in height: Exactly two rack units consumed — predictable in rack elevation drawings. At 19 inches wide it's a standard EIA-310 fit with no modification.
• 10 ft Power Cord: Long enough to reach a dedicated 20A wall circuit from a floor-standing rack without extension cords, which matters both for code compliance and for UPS warranty terms that typically void on extension cord use.

Deployment Considerations:

• Shipping weight is 54 lbs — before committing to a wall-mount rack, verify the enclosure and wall anchor system are rated for that load plus the rest of the rack contents. A 54 lb UPS plus a loaded NVR and switch in a 6U wall box adds up fast.
• TAA non-compliance is a hard stop for federal and many state/local government projects. Confirm procurement rules with the project owner before the equipment list is finalized — swapping UPS models late in a bid is a real scheduling problem.

The UPS-S1500R is the right call for a commercial integrator standing up a mid-density physical security rack in a retail, corporate, or light industrial environment where power quality is reasonable and the goal is ride-through on short outages plus controlled shutdown on longer ones — not a generator-backed mission-critical data center scenario.
