Electrical

The following section provides information about the PXIe-1084 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[1]

90 to 264 VAC

Nominal input frequency

50 Hz/60 Hz/400 Hz[2]

Operating frequency range[1]

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. With the Timing and Synchronization upgrade, you can use the rear-panel 15-pin connector and inhibit mode switch to control the internal chassis power supply.

Caution Disconnect power cord to completely remove power.
