Determines the voltage limit, in volts, beyond which overvoltage protection (OVP) engages. Limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously. For example, setting the OVP Limit to 65 will configure the OVP feature to trigger an OVP error if the output exceeds ±65 V.

Syntax

Namespace: NationalInstruments.ModularInstruments.NIDCPower

public double OvpLimit { get; set; }

Remarks

Valid values vary by device. Refer to the Supported Properties by Device topic in the NI DC Power Supplies and SMUs Help for the default value by instrument.

Refer to the Output Overvoltage Protection topic in the NI DC Power Supplies and SMUs Help for more information about overvoltage protection.
Note

NI-DCPower uses the terms "source" and "output". However, while sinking with electronic loads and SMUs these correspond to "sinking" and "input", respectively.

Note

This property is not supported by all instruments. Refer to the Supported Properties by Device topic in the NI DC Power Supplies and SMUs Help for information about supported instruments.
