Middle Atlantic Select Series UPS Backup Power 1RU 1000VA - UPS-S1000R

Middle Atlantic UPS-S1000R Select Series 1000VA 1RU Rack UPS

Overview

The Middle Atlantic UPS-S1000R is a 1000VA rack-mount battery backup unit built specifically for AV and physical security infrastructure — the kind of load profile you see in surveillance head-end racks, access control panels, and network closets running cameras, switches, and NVRs around the clock. At just 1RU tall, it slides into a standard 19-inch rack without consuming the vertical space that larger UPS units typically demand, keeping your rack layout tight. If you've built out a security rack and lost two or three rack units to a bulky UPS, the single-rackunit footprint of the UPS-S1000R is worth noting upfront.

Middle Atlantic has a long history designing power and rack infrastructure for integrators, and this unit fits cleanly into the Middle Atlantic power and rack lineup. It carries a UL Listing, which matters for installations where local inspection requires it.

Key Features

• 1000VA Capacity: 1000VA gives you enough headroom for a small-to-mid surveillance head end — think a 16-channel NVR, a PoE switch, and a couple of ancillary devices. Run your load calculation before assuming it covers everything; 1000VA is not a whole-closet solution, but it's the right size for a focused security rack.
• 1RU Form Factor (1.73 in tall, 19 in wide): A single rack unit at standard 19-inch width means it installs in virtually any EIA-310 rack. At 1.73 inches, it won't throw off your cable management or push equipment past the rail. This matters in shallow wall-mount enclosures where every inch counts.
• 15.31-Inch Chassis Depth: The unit itself is 15.31 inches deep. Combined with the rack depth range of 19 to 32 inches, it installs in most standard two-post and four-post racks without rear-clearance issues. Confirm your shallowest rack rail depth before ordering — 19-inch minimum mounting depth is the floor.
• 6 Outlets: Six outlets let you distribute backup power across multiple devices in the rack without a secondary PDU in most single-rack deployments. Separate your critical loads (NVR, core switch) from non-critical ones (monitors, peripherals) if your topology allows it.
• 10 ft Corded Input: The 10-foot (3.1m) power cord gives you genuine flexibility in where the rack sits relative to the wall circuit. In server rooms and IT closets where PDUs and floor outlets are common, extra cord length eliminates the need for extension cords or repositioning the rack.
• 2 Mounting Points: Two front-mounting points are standard for 1RU rack equipment. Use cage nuts appropriate for your rack's rail type — Middle Atlantic racks use their own rail system, but the UPS-S1000R is sized for standard EIA rails as well.
• UL Listed: UL Listing is a hard requirement in many commercial and government installations. The UPS-S1000R meets that bar, which simplifies the AHJ (authority having jurisdiction) inspection process on projects where the electrical inspector will be checking the rack.
• Basic Surge Protection: Surge protection is included. This is characterized as basic-level surge suppression — adequate for line conditioning on a clean commercial circuit, but not a substitute for whole-panel surge protection on sites with known power quality issues.

Integration & Compatibility

The UPS-S1000R integrates into any rack UPS and power management strategy where 1RU space and 1000VA capacity align with the load. It is not TAA compliant, which means it is not the right choice for federal government projects subject to Trade Agreements Act procurement requirements — confirm TAA status with your contracting officer before specifying on government work.

For surveillance-specific deployments, pair this unit with an NVR and managed PoE network switches — two device classes that benefit most from protected, conditioned power. Unplanned power loss during active recording can corrupt NVR databases; even a few minutes of UPS runtime gives the NVR time to complete a clean shutdown or finish writing buffered footage. Review the power protection planning guide for help sizing UPS capacity against your actual camera and switch draw.

The UPS-S1000R (often searched as UPS S1000R) ships at 36 lbs — plan for two people during rack installation. At that weight, securing it properly with both mounting points before releasing is not optional.

Frequently Asked Questions

Q: Is the UPS-S1000R TAA compliant for federal government projects?

A: No. The UPS-S1000R is not TAA compliant. If your project requires Trade Agreements Act compliance, you will need to specify a different unit. Confirm procurement requirements with your contracting officer before specifying on any government project.

Q: What is the minimum rack depth required to install the UPS-S1000R?

A: The minimum mounting depth is 19 inches, with a maximum of 32 inches. The unit's chassis depth is 15.31 inches (38.9 cm). Confirm your rack's usable rail-to-rail depth before ordering.

Q: How many outlets does the UPS-S1000R provide?

A: Six outlets total. All are on-battery outlets with basic surge protection. There is no evidence of separate always-on or surge-only outlet banks in the available specifications.

Q: How much does the UPS-S1000R weigh, and do I need two people to install it?

A: Shipping weight is 36 lbs (16.3 kg). At that weight, two-person installation in a rack is strongly recommended — attempting solo rack insertion at that mass increases risk of rail damage and injury.

Q: What is the UPS-S1000R's VA rating, and is it sufficient for a 16-channel NVR and PoE switch?

A: The unit is rated at 1000VA. Whether that covers your specific NVR and switch depends on the actual watt draw of those devices. Calculate your total connected load in watts before assuming the 1000VA rating is sufficient — VA and watts are not the same figure, and actual watt capacity will be lower than the VA number.

Q: Is the UPS-S1000R UL Listed?

A: Yes, the UPS-S1000R is UL Listed, which satisfies the electrical inspection requirement on most commercial installations in the United States.

Ted Perry

The UPS-S1000R is one of those rack components that gets specified without much drama when the numbers line up — 1000VA in 1RU at a 15.31-inch chassis depth. What I tell integrators is: the depth spec is where projects go sideways. If you're dropping this into a 19-inch shallow wall enclosure, you're at the minimum mounting depth of 19 inches. That works, but there's zero margin — verify the actual interior depth of your enclosure with a tape measure before the unit ships.

Technical Highlights:

• 1RU / 1.73 in tall: In a typical 12U or 16U security rack, losing one unit to the UPS versus two or three to a larger unit makes a real difference when you're also racking an NVR, patch panel, and managed switch.
• 6 Outlets: Six protected outlets cover the typical head-end load — NVR, core PoE switch, maybe a fiber converter or access control panel — without needing a secondary PDU in most single-rack builds.
• UL Listed: On commercial retrofit jobs where the electrical inspector pulls the panel and checks the rack, having the UL mark on the UPS avoids the conversation about whether the unit is approved for permanent installation.

Deployment Considerations:

• At 36 lbs shipping weight, the actual unit is heavy for 1RU. Plan the install sequence so the UPS goes in after the rack is anchored and before the gear above it is populated — sliding 30-plus pounds into a loaded rack at chest height is awkward at best.
• The TAA non-compliance is a hard stop on E-rate and GSA schedule projects. Don't get this spec'd into a government bid without confirming the procurement vehicle allows non-TAA items — pulling a UPS from a nearly complete rack install is an expensive correction.

The UPS-S1000R fits cleanly in commercial surveillance head-end racks at retail, hospitality, and mid-size enterprise sites where the load is a 16-channel NVR plus a PoE switch and the project budget doesn't support a larger managed UPS — it does the job in the space without overcomplicating the installation.
