The NI PXI-4110 has two isolated channels, one from 0 to +20 V and the other from 0 to -20 V, and a single nonisolated 0 to 6 V supply, all capable of sourcing up to 1 A per channel. The PXI-4110 has 16-bit resolution for programming the voltage setpoint and current limit and for using the voltage and current readback measurement functionality. The versatile supply rails and high accuracy make the PXI-4110 an excellent general-purpose, single-quadrant power supply for design validation and manufacturing test applications. You can power the PXI-4110 either internally from the PXI backplane or externally through the NI APS-4100, a front-panel-connected auxiliary DC supply. Using internal power reduces the number of connections required on the front panel but also limits the available output power because of per-slot PXI power restrictions. When internally powered, the nonisolated, 0 to 6 V channel can be operated at its full 1 A current range, but the isolated channels are limited to 100 mA. When externally powered, all channels can be operated at full power of 1 A per channel for a total maximum output power of 46 W. Power Supply with Precision Source Capability The PXI-4110 has the ability to source both voltage and current from each of its three outputs. As a voltage source, it can be programmed in 120 µV steps on the +6 V channel and 400 µV steps on each of the 20 V channels. As a current source, it can be programmed in 20 µA steps on each channel in the 1 A current range. Additionally, you can set each of the 20 V channels to a 20 mA current range for 400 nA programming resolution. You can use this impressive level of current resolution in traditional power supply applications or in many applications that typically require a separate precision source measure unit. Linear Supply with Switching Preregulation The PXI-4110 uses a combination of switching and linear regulation to provide excellent output power and accuracy in the 3U PXI module. On each channel, input power (coming from either the PXI backplane or the APS-4100) is regulated to within a certain percentage of the desired output power. This preregulation stage is governed by an intelligent PID algorithm implemented on board the module, ensuring the amount of power passed to the second (linear) stage is at the most efficient level, given the desired output. After additional filtering, you can use traditional linear regulation techniques and amplification to further regulate the signal and source the final voltage or current. Because the output is linearly regulated, it has very quick load response and high precision – even at levels as low as 0 V. Also, because the linear regulation occurs on the preregulated signal, the power dissipation is relatively small and easily cooled in a PXI slot. Triple-Output Programmable DC Power Supply Preregulation Control Transformer Rectifier and Filter Power Amplifier Current Sense (20 mA/1 A) Load Linear Regulation (Isolated Channels Only) Current Feedback Voltage Feedback Internal Power Auxiliary Power (Isolated Channels Only) + Power Switch – Architecture of Single Isolated Channel on the PXI-4110 Extensive Protection Features The PXI-4110 operates with only nominal temperature increases internally due to the intelligent PID control of the output devices. If an overtemperature condition occurs in the PXI chassis due to fan failure or intake blockage, the output channels are shut down and a warning is issued. This type of condition requires user software intervention to reset, thus preventing the module from damage at excessive temperatures. Software NI-DCPower, an IVI-compliant instrument driver, offers complete programmatic control of the PXI-4110. You can use an available test panel to quickly troubleshoot or debug power supply operation and take advantage of the DCPower Express VI for an intuitive, configurationbased method of programming in the National Instruments LabVIEW graphical development environment. In addition to the standard voltage and current limiting functionality of the PXI-4110, several other features are included to protect the supply and the load. Each output is protected against a reverse-polarity voltage application as well as excessive voltages – up to 15 V above the maximum channel voltage. Output fuses provide additional protection to prevent catastrophic failure as a last line of defense. The operating voltage range for the auxiliary power input is 11 to 15.5 V. If voltages outside these limits are detected, the module shuts down until an input voltage within range is applied. If an input in excess of 20 V is applied, the input crowbar protection turns on, protecting the input solid-state switching devices (and preregulator power supply) from overvoltage damage.
