Overload Protection (OLP)

The PXIe-4145 is protected against overcurrent (OCP) conditions.

Note Refer to NI-DCPower Overload Protection Error (OLP) Codes for more information about these NI-DCPower errors.

Overcurrent Protection (OCP)

Overcurrent Protection (OCP) engages protection circuitry when the maximum specified current has been surpassed. This feature disables the output of the affected channel and disconnects the channel circuitry from the output connector pins. By internally disconnecting the output, it protects both the PXIe-4145 and the device under test (DUT).

To clear an OCP condition, first identify and fix the cause of the error and then reset the channel or device in MAX or use the niDCPower Reset Device VI or the niDCPower_ResetDevice function.

Do not apply voltages at the output that exceed the ratings of the PXIe-4145. Refer to the PXIe-4145 Specifications for information about voltage ratings.
