IviACPwrBase Behavior Model
After you call the IviACPwr Initialize, IviACPwr Initialize with Options, or IviACPwr Reset VIs, the driver must immediately disable output power and set the Output Enabled property to False for all output phases. The driver must then set all extension capability groups to the disabled state. Refer to the Disabling Unused Extensions (IviACPwr) topic for more information about disabling extensions. You must determine if the attribute values in the IviACPwrBase capability group are appropriate or safe for their load prior to setting the Output Enabled property to True.
All changes to the IviACPwrBase VIs and properties take place immediately.
