Definitions

Warranted Specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical—describes the performance met by a majority of models.
  • Nominal—describes an attribute that is based on design, conformance testing, or supplemental testing.

    • Values are Typical unless otherwise noted.

    Conditions

    Specifications are valid under the following conditions unless otherwise noted.

    • Indoor use only
    • The product is operated within the Environmental limits described in this document, including:
      • Altitude and pollution degree as specified in Environmental Characteristics
      • Ambient temperature and relative humidity as specified in Operating Environment (per-slot power profiles apply)

    Electrical

    The following section provides information about the PXIe-1081 AC input and DC output.

    AC Input

    Input rating 100 to 240 VAC, 50/60 Hz, 10 to 5 A, 100 to 120 VAC, 400 Hz, 10 A
    Operating voltage range 90 to 264 VAC
    Nominal input frequency 50 Hz/60 Hz/400 Hz
    Operating frequency range 47 to 440 Hz
    Efficiency 85%, typical
    Over-current protection Internal fuse in line
    Main power disconnect The AC power cable provides main power disconnect. Do not position the equipment so that it is difficult to disconnect the power cord. The front-panel power switch causes the internal chassis power supply to provide DC power to the PXI Express backplane.
    Caution Disconnect power cord to completely remove power.
    Note The operating range is guaranteed by design, with the exception that 400 Hz operation is only supported from 100 to 120 VAC.
