NI PXI-4110

The NI PXI-4110 has three single-quadrant DC power supply channels. The following table lists the DC voltage ranges supported by each channel.

Channel	Range
	Output	Measurement
0	+6 V	+6 V
1	+20 V	+20 V
2	-20 V	-20 V
These channels support 5% overranging when overranging is enabled.

The following table lists DC current ranges supported by the NI PXI-4110.

Channel	Range
	Output	Measurement
0	1 A	1 A
1 and 2	20 mA	20 mA
	1 A*	1 A*
*Without auxiliary power, the maximum current in the 1A range is 100 mA.
These channels support 5% overranging when this overranging is enabled.

The following diagrams illustrate the output voltage and current capabilities of each channel on the NI PXI-4110:

       

Note  Channel 2 on the NI PXI-4110 is a single-quadrant power supply and always operates within Quadrant III. However, the polarity of the measured voltage is negative (measured using the niDCPower Measure VI or the niDCPower Measure Multiple VI) and the polarity of the measured current is positive. The difference in polarities is due to the positive current direction on channel 2 being defined as current flowing into the common floating GND.
