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

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. |
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. |
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
