PXI-4110 programmable DC power supply

Engineers now can source voltage or current with high accuracy from a single PXI slot with the National Instruments PXI-4110 programmable DC power supply.

The power supply exceeds the accuracy of other PXI power supplies with high-resolution setpoints and read-back measurement capability while reducing test times with programming speeds less than 1 ms.

It is suitable for applications such as I-V curve tracing, device characterisation or device power sourcing in a variety of industries.

The NI PXI-4110 is a programmable, triple-output precision DC power supply in a single slot, 3U PXI module. It has two isolated channels, one from 0 to +20 V and the other from 0 to -20 V, and a single non-isolated 0 to 6 V supply - all capable of outputting up to 1 A per channel.

Engineers can use the module's 16 bit resolution setpoints, selectable 20 mA current range and read-back measurements to program 0.12 mV changes in voltage and 0.4 mA changes in current to meet test specification requirements.

With less than 1 ms programming speed, engineers can perform fast voltage/current sweeps across a device, reducing total test time compared to traditional GPIB or serial controlled power supplies by more than 10 times.

The module offers 9 W of output power when operating from the PXI backplane supply and up to 46 W of power (maximum of 20 W per channel) when connected to an auxiliary power supply through the module's front panel.
