PXI-4130 Internal and Auxiliary Power

The PXI-4130 can generate limited power on backplane power but requires the use of an auxiliary power supply to generate up to its full current capability.

When drawing internal power from the PXI backplane, channel 1 of the PXI-4130 can source or sink up to 2 W of output power at ≤300 mA. Figure 1 shows the maximum capabilities of channel 1 when operating under internal power.

Note Channel 0 has the same output capabilities under internal power and auxiliary power.

If your application requires additional current on this channel, up to a maximum of 2 A, you must connect an auxiliary DC power supply that meets the following requirements:

  • Auxiliary power supply voltage— 11 V to 15.5 V
  • Auxiliary power supply wattage— ≥60 W

    • NI offers the APS-4100 auxiliary power source for this instrument. The power supply is included in the instrument kit.
