PXI-4110 Overview

The PXI-4110 is a triple-output, single-quadrant, programmable power supply in a single-slot, 3U PXI module. It is designed for engineers performing design validation and manufacturing test applications. Use the PXI-4110 for constant voltage (CV) applications or PXI-4110 constant current (CC) operation with programmable setpoint levels and limits. Voltage and current applications support measurement readback.

Device Capabilities

The PXI-4110 has the following channel capabilities.

  • Channel 0: 0 V to 6 V, 1 A, 6 W power supply.
  • Channel 1: 0 V to 20 V, 1 A, 20 W (with auxiliary supply) or 2 W (internally powered), bank-isolated[1]1 In bank isolation, or channel-to-bus isolation, several physical lines are built into groups called banks. The ground loop protection is high between banks because isolation barriers exist between channels in different banks. However, it is still possible for signals on channels within a bank to affect each other. power supply.
  • Channel 2: -20 V to 0 V, 1 A, 20 W (with auxiliary supply) or 2 W (internally powered), bank-isolated power supply.
Note When internally powered, the combined outputs of Channels 1 and 2 must not exceed 3 W.
