|NI-DCPower (English | Japanese)|
NI PXIe-4136/4137 is protected against overcurrent and overvoltage conditions. These conditions can cause protection circuitry to engage, which 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 NI PXIe-4136/4137 and the device under test.
|Caution Do not apply voltages at the output that exceed the ratings of the NI PXIe-4136/4137. Refer to the NI PXIe-4136/4137 specifications for information about voltage ratings.|
Overvoltage Protection (OVP) protects the user's DUT from high voltage events by disabling the output when the OVP limit is exceeded.
You can set an OVP limit for the NI PXIe-4136/4137 to limit the maximum DC voltage at the output pins. The OVP limit applies to the output of the local sense pins, regardless of the selected sense mode. To set the OVP limit, use the niDCPower OVP Limit property or the NIDCPOWER_ATTR_OVP_LIMIT attribute and enable OVP using the niDCPower OVP Enabled property or the NIDCPOWER_ATTR_OVP_ENABLED attribute. For the default OVP limit, refer to Supported Properties by Device.
