Middle Atlantic UPS-OL3000R – Online UPS 3000VA 120V Rackmount

Product Overview

The Middle Atlantic UPS-OL3000R is a 3000VA online (double-conversion) rackmount UPS providing continuous pure sine wave power conditioning and battery backup for AV racks and sensitive electronic systems. Online double-conversion topology means connected equipment runs on inverter-supplied power at all times, providing zero-transfer-time protection against all power anomalies including sags, surges, brownouts, and complete outages. It operates on 120V AC and mounts in a standard equipment rack for integration into AV and IT infrastructure.

Product Description

The UPS-OL3000R uses online double-conversion architecture, which differs fundamentally from standby and line-interactive UPS designs. In a double-conversion system, incoming AC power is first rectified to DC, then inverted back to AC, meaning the connected load always runs on clean, regulated inverter output regardless of input power quality. This eliminates the transfer switching delay present in standby UPS units and provides complete galvanic isolation between the utility input and the protected output.

At 3000VA capacity, this unit supports substantial AV rack loads including multiple amplifiers, video processors, control systems, network switches, and other power-sensitive equipment. The pure sine wave output is required for equipment with active power factor correction (PFC) power supplies, which are standard in most modern professional AV and IT hardware. Modified sine wave UPS units are not appropriate for PFC power supplies and can cause premature equipment failure or improper operation.

The UPS-OL3000R is designed by Middle Atlantic specifically for professional AV rack applications, meaning it is sized and configured to integrate physically and electrically with standard 19-inch rack enclosures. Rackmount form factor keeps the UPS in the same enclosure as the equipment it protects, reducing cabling complexity and enabling clean rack layouts. The unit provides power management features appropriate for AV integrators and systems operators managing critical uptime requirements.

Frequently Asked Questions

Q: What is the difference between online double-conversion and line-interactive UPS?

A: A line-interactive UPS switches to battery during an outage, introducing a brief transfer time (typically 4–16ms). An online double-conversion UPS continuously runs the load on inverter output, so there is zero transfer time. For sensitive AV and IT equipment, double-conversion is the more protective topology.

Q: Why does professional AV equipment require pure sine wave UPS output?

A: Most modern professional AV and IT equipment uses active power factor correction (PFC) power supplies. PFC supplies require a pure sine wave input to operate correctly. A modified sine wave UPS can cause overheating, erratic behavior, or damage in PFC-equipped equipment.

Q: How much runtime does the UPS-OL3000R provide?

A: Runtime depends on the actual load. A lighter load provides longer runtime; a load near 3000VA will reduce runtime significantly. Refer to the Middle Atlantic runtime curve for the UPS-OL3000R for specific estimates.

Q: Can the UPS-OL3000R be used with a generator?

A: Yes. The online double-conversion design isolates the output from generator-induced frequency variations and voltage irregularities, making it well-suited for generator-backed installations.

Q: What rack space does the UPS-OL3000R occupy?

A: Consult the Middle Atlantic product datasheet for exact rack unit height. Contact creationnetworks.net for current spec sheets and installation guidance.

Q: Is this available for purchase through Creation Networks?

A: Yes. Visit creationnetworks.net for pricing and availability.
