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
