|NI-DCPower (English | Japanese)|
When drawing internal power from the PXI backplane, channel 1 of the NI PXI-4130 can source or sink up to 2 W of output power with a maximum current of 300 mA. The following figure illustrates the maximum capabilities of channel 1 when operating under internal power.
If your application requires additional current, you can connect an auxiliary DC power supply capable of providing 11 V to 15.5 V and ≥60 W to increase the output current capability of this channel to 2 A. NI offers the APS-4100, an auxiliary power source for NI DC power supplies. Visit ni.com for more information.
|Note Channel 0 has the same output capabilities under internal power and auxiliary power.|
Complete the following steps to connect and use auxiliary power:
|Tip Use the niDCPower Power Source In Use property or the NIDCPOWER_ATTR_POWER_SOURCE_IN_USE attribute to programmatically determine which power source is in use.|
In case of auxiliary power loss during operation, the isolated output (channel 1) is disabled, and the power supply is shut down to prevent damage to the NI PXI-4130 and the load. If a shutdown occurs, complete the following steps to resume operation:
Complete the following steps to change or remove auxiliary power from the NI PXI-4130:
|Tip It is often more convenient to close the existing session and open a new session to the device when managing auxiliary power state changes.|
