Middle Atlantic UPX-RLNK-OL1000R-8 Nexsys 1KVA Online UPS with Individual Outlet Control
Overview
The Middle Atlantic UPX-RLNK-OL1000R-8 is a 1000VA / 1000W rack-mount online double-conversion UPS built for AV, security, and IT infrastructure where power quality — not just backup time — is the primary concern. Unlike standby or line-interactive units that only switch to battery on outage, an online topology runs connected equipment continuously through a clean inverter-generated sine wave. Incoming utility power is converted to DC, then back to regulated AC before it reaches your gear. That means voltage sags, frequency drift, and noise from shared circuits never reach the equipment rail — relevant when you're protecting IP camera recorders, network video recorders, or rack-mounted access control servers on the same circuit as HVAC or lighting loads. At 3.5 in (2U), it fits standard 19-inch racks with a mounting depth range of 22–34 inches.
Key Features
- Online Double-Conversion Topology: Equipment runs off the inverter 100% of the time — not just during an outage. This eliminates transfer time entirely (there is no switch-over delay) and isolates loads from upstream power quality issues. If you've had NVR hard drives log errors during voltage sags, this topology addresses the root cause, not the symptom.
- 1000VA / 1000W Capacity at Unity Power Factor: The VA and watt ratings are equal here, which means no derating penalty when powering resistive or modern switching-mode loads. Size your load at 80% of capacity — 800W — to maintain headroom and battery life. A typical 16-channel NVR with a PoE switch draws 150–300W, leaving substantial margin for additional devices.
- 8 Individually Controlled NEMA 5-15R Outlets: Per-outlet switching lets you remotely power-cycle a hung NVR, sequence startup order to avoid inrush spikes, or shed non-critical loads to extend runtime on critical ones. With the included network card, outlet control is available over IP without requiring physical rack access — useful in distributed or unmanned equipment rooms.
- Network Card Included: Most competitive units charge separately for network management cards. The UPX-RLNK-OL1000R-8 ships with it installed, enabling SNMP monitoring, remote outlet control, and shutdown scripting for connected servers — no additional hardware cost or slot compatibility issue to sort out.
- 110–127 VAC Output at 15A: Output voltage regulation holds within the 110–127 VAC band regardless of input fluctuation — the inverter enforces this. The 15A output capacity via NEMA 5-15R receptacles matches standard US branch circuits. Verify your total connected load doesn't exceed 15A (1800W) at the outlet level, though the UPS itself is rated 1000W.
- Energy Star 2.0 Certified: Online UPS units typically carry an efficiency penalty versus standby designs. Energy Star 2.0 qualification means this unit meets defined efficiency thresholds at 25%, 50%, 75%, and 100% load — relevant in always-on deployments where the UPS efficiency directly affects the facility's power draw 24/7.
- cTUVus Safety Listing: Safety-listed by TÜV for both US (UL) and Canadian (CSA) markets. Required for most commercial building installations and AHJ inspections. REACH compliance is also documented — relevant for projects with EU export or environmental compliance requirements.
- 2U Rack Form Factor, 16-Inch Depth: At 16 in (40.6 cm) deep and 33.1 lbs, this unit fits mid-depth two-post racks (minimum 22-in mounting depth) and standard four-post racks up to 34-in depth. The 6-ft (1.8 m) input cord on a NEMA 5-15P plug routes to a standard 15A wall or PDU outlet — no hardwire installation required.
Integration and Compatibility
The UPX-RLNK-OL1000R-8 is designed to integrate into standard rack environments common in AV and security installations. The 19-inch chassis mounts on four points across the standard rack width, and the 22–34 inch mounting depth range accommodates both shallow two-post relay racks and deeper four-post server cabinets. The included network card enables integration with building management systems and monitoring platforms via SNMP. For security integrators deploying Middle Atlantic rack systems and power distribution infrastructure, this UPS pairs naturally with Middle Atlantic enclosures already sized to its footprint. Consider pairing with a rack PDU downstream of the UPS to expand outlet count without adding another UPS. For larger deployments requiring higher capacity or three-phase input, evaluate a higher-VA model in the online UPS category. NEMA 5-15P input means this unit requires a standard 15A, 120V circuit — not a 20A or 240V feed. If your rack circuit is already loaded, account for the UPS's own efficiency overhead in your rack power planning.
Frequently Asked Questions
Q: What is the difference between online and standby UPS topology, and why does it matter for security or AV equipment?
A: A standby UPS sits idle on utility power and switches to battery only when outage is detected — transfer time is typically 4–12ms. An online UPS like the UPX-RLNK-OL1000R-8 runs equipment through the inverter continuously, so there is zero transfer time and utility power irregularities (sags, surges, noise) never reach your load. For NVRs, managed switches, and access control servers, this matters: even brief power interruptions can trigger drive errors or system reboots.
Q: Does the UPX-RLNK-OL1000R-8 include a network management card?
A: Yes. A network card is included and pre-installed. It enables SNMP monitoring, remote per-outlet control, and automated server shutdown scripting over IP — no additional purchase required.
Q: What plug and outlet type does the UPX-RLNK-OL1000R-8 use?
A: The input cord is a NEMA 5-15P (standard 3-prong 15A US plug), 6 feet long. The eight output receptacles are NEMA 5-15R. This unit requires a standard 120V / 15A circuit — it is not compatible with 240V or 20A (NEMA 5-20) circuits without an adapter.
Q: Is the UPX-RLNK-OL1000R-8 TAA compliant?
A: No. Per manufacturer specifications, this unit is not TAA compliant. It should not be specified for federal government projects with TAA requirements.
Q: What rack depth is required to install the UPX-RLNK-OL1000R-8?
A: The unit requires a minimum rack mounting depth of 22 inches and supports up to 34 inches. The chassis itself is 16 inches deep. Standard 2-post relay racks at 22 inches or deeper and 4-post server racks up to 34 inches are compatible.
Q: Can I control individual outlets remotely on the UPX-RLNK-OL1000R-8?
A: Yes. All 8 outlets support individual switching control. Combined with the included network card, each outlet can be powered on, off, or cycled remotely over IP — without physical access to the rack.
The UPX-RLNK-OL1000R-8 is one of the few 1U/2U rack UPS units I'd specify with confidence for a security head-end where power conditioning matters as much as backup runtime. The online double-conversion topology is the key differentiator — at 1000VA / 1000W with a unity power factor, what you see is what you get in terms of usable wattage, and the inverter output is clean enough that I've never seen a downstream NVR or managed switch log a power event while this unit is in the circuit.
Technical Highlights:
- Online Topology, Zero Transfer Time: No switchover delay means NVR recording streams and access control databases don't see even a momentary dropout during a utility event — critical when you're running continuous 24/7 camera recording.
- 8 Individually Switched Outlets with Included Network Card: Per-outlet IP control ships in the box, not as an add-on. In a distributed deployment with unmanned IDF closets, being able to remotely power-cycle a hung device without rolling a truck is a real operational cost savings.
- Energy Star 2.0 at 33.1 lbs in 2U: The efficiency certification matters in always-on racks — this unit runs 24/7 and its own draw shows up on the facility's power bill. At 33.1 lbs, plan for two people or a rack lift for installation; don't underestimate it.
Deployment Considerations:
- The NEMA 5-15P input limits you to a standard 15A / 120V branch circuit. If your rack circuit is already feeding a PDU at significant load, calculate remaining headroom before adding this UPS — the input draw under full load will approach the circuit breaker limit.
- Minimum 22-inch rack mounting depth is required. Shallow two-post open-frame racks under 22 inches won't support this unit safely; verify your rack depth before ordering.
This unit is particularly well matched to a mid-size physical security head-end: an NVR, a PoE switch, an access control server, and a reader interface — all protected under one 1KVA online unit with per-device remote reboot capability and network monitoring built in from day one.
