DC Current Load

The DC Current Load subcircuit models a constant current load. Unlike the Resistive Load, the DC Current Load uses a pure current source.

Parameters

The following table explains the relevant parameters.

Parameter Name	Default	Data Type	Range	Units	Parameter Description
LOAD_NAME	LOAD	String	n/a	n/a	Name of the DVM load. This name cannot contain spaces.
DC_CURRENT	500m	Real	Min: 0	A	Sets the load current of the load.

DVM Testplan Entry

To set any managed DVM load to a DC Load subcircuit, place a Dc() testplan entry in the Load column.

The Dc() testplan entry has the following syntax with the arguments explained in the table below.

Dc(REF, DC_CURRENT)

Argument	Range	Description
REF	n/a	The actual reference designator of the DVM load or the more generic syntax of OUTPUT:`n` where `n` is an integer indicating a position in the list of DVM loads.
DC_CURRENT	min: 0	The DC current for the load.

Converting between DVM and Power Supply Loads

To change a Power Supply load to a DVM load, right click the symbol to bring up the context menu, and select the menu option: Upgrade to DVM Source/Load

To change a DVM load to a Power Supply load, right click the symbol to bring up the context menu, and select the menu option: Downgrade to SIMetrix/SIMPLIS Source/Load
