Middle Atlantic OL1500R-8 vs ATEN OL1500LV: Specification Comparison
Both the Middle Atlantic UPX-RLNK-OL1500R-8 (OL1500R-8) and the ATEN OL1500LV are 1.5 kVA rack-mount online (double-conversion) UPS units targeting AV, IT, and security infrastructure installations. At the same VA class and the same topology, a buyer evaluating either for a 1U/2U rack environment would reasonably cross-shop them. The comparison examines outlet management and load control, physical and power specifications, and remote monitoring and software integration—the three axes most relevant to integrators deploying UPS units in managed rack environments.

How much per-outlet control and load management does each unit provide?
The OL1500R-8 ships with individual outlet control as a named specification, with 8 NEMA 5-15R receptacles each independently switchable. This is a core differentiator for AV and security integrators who need to sequence power, remotely reboot hung devices, or shed non-critical loads without dropping the entire UPS output. The model name itself encodes this capability (RLNK = Rack Link individual control).
The OL1500LV's provided specifications do not list outlet count, individual outlet switching, or any per-outlet control capability. The package contents include an RS-232 cable and USB Type-A to B cable, which are consistent with UPS management but do not confirm per-outlet switching. Buyers requiring outlet-level control cannot confirm that capability from the published ATEN specs.
What are the key power ratings, physical dimensions, and environmental tolerances?
The OL1500R-8 is rated at 1500 VA / 1350 W, operates on 110–127 VAC output, draws up to 15 A on a NEMA 5-15P input cord, and occupies a 19 × 3.5 × 16 in (W×H×D) chassis weighing 44.7 lbs (20.3 kg). Rack depth compatibility is specified at 22–34 in minimum to maximum mounting depth. Operating temperature is confirmed at 32–104°F (0–40°C).
The OL1500LV's published specifications confirm only the 1.5 kVA class designation and a weight of 14.60 kg (32.16 lb)—roughly 32 lbs versus the OL1500R-8's 44.7 lbs. Wattage (W) output, input voltage range, input amperage, chassis dimensions, rack unit height, and operating temperature are all absent from the provided spec set. The significant weight difference (≈13 lbs lighter) may reflect a smaller battery, different inverter topology detail, or simply incomplete published specs; no conclusion about battery capacity or runtime can be drawn.
What remote monitoring, software integration, and compliance credentials does each unit carry?
The OL1500R-8 carries cTUVus safety certification and Energy Star 2.0 compliance, along with REACH declaration. No SNMP card, network management port, or software suite is listed in the provided specifications; remote monitoring capability is not confirmed from the published data.
The OL1500LV explicitly lists optional SNMP/HTTP remote monitoring via an add-on SNMP card, and ships with ViewPower software supporting Linux, macOS, and Windows, plus a ShutdownWizard for Windows. Management cabling (RS-232 and USB) is included in the box. Regulatory approvals include FCC Class A, RoHS, VCCI, and BSMI. Energy Star compliance and TAA status are not stated in the provided ATEN specs.
Which should you choose: the OL1500R-8 or the OL1500LV?
Our take: The OL1500R-8 is the stronger choice when per-outlet switching, precise wattage headroom, and North American safety certification are the primary selection criteria. It delivers a fully specified 1500 VA / 1350 W output with 8 individually controlled NEMA 5-15R outlets, a confirmed cTUVus listing, and Energy Star 2.0 compliance—details the OL1500LV spec sheet does not address. The OL1500LV, by contrast, is the stronger choice for managed-network deployments: its optional SNMP card enables HTTP/SNMP monitoring, ViewPower software supports multi-OS graceful shutdown, and its 32.16 lb weight is roughly 13 lbs lighter than the OL1500R-8's 44.7 lbs. Buyers deploying in a monitored IT rack with existing network management infrastructure and no requirement for per-outlet switching should evaluate the OL1500LV further, while AV and physical-security integrators needing individual outlet reboot control should favor the OL1500R-8.

Frequently Asked Questions
Which should you choose: the OL1500R-8 or the OL1500LV?
The OL1500R-8 is the stronger choice when per-outlet switching, precise wattage headroom, and North American safety certification are the primary selection criteria. It delivers a fully specified 1500 VA / 1350 W output with 8 individually controlled NEMA 5-15R outlets, a confirmed cTUVus listing, and Energy Star 2.0 compliance—details the OL1500LV spec sheet does not address. The OL1500LV, by contrast, is the stronger choice for managed-network deployments: its optional SNMP card enables HTTP/SNMP monitoring, ViewPower software supports multi-OS graceful shutdown, and its 32.16 lb weight is roughly 13 lbs lighter than the OL1500R-8's 44.7 lbs. Buyers deploying in a monitored IT rack with existing network management infrastructure and no requirement for per-outlet switching should evaluate the OL1500LV further, while AV and physical-security integrators needing individual outlet reboot control should favor the OL1500R-8.
Can I remotely reboot a single device without cutting power to the whole rack on either unit?
The OL1500R-8 explicitly specifies individual outlet control across all 8 NEMA 5-15R receptacles, making per-device remote reboot a confirmed capability. The OL1500LV's published specifications do not list individual outlet switching; that capability cannot be confirmed from the provided data.
Which unit is easier to integrate into a network monitoring platform via SNMP?
The OL1500LV lists optional SNMP/HTTP remote monitoring via an add-on SNMP card, and includes ViewPower software and RS-232/USB management cables in the box. The OL1500R-8's provided specifications do not mention a network management port or SNMP capability, so SNMP integration cannot be confirmed for that model from the published specs.
Which unit is lighter and easier to handle during installation in a deep equipment rack?
The OL1500LV weighs 14.60 kg (32.16 lb) versus the OL1500R-8 at 20.3 kg (44.7 lb)—a difference of approximately 12.5 lb. The OL1500R-8 also specifies a mounting depth range of 22–34 inches; no equivalent mounting depth spec is published for the OL1500LV.
