Overview of instrument
The DC Load is a two terminal device that can be connected to DC sources. Here, a DC source is a
voltage that is always positive on the DC Load's + terminal referenced to the - terminal.
DC Electronic Loads are used for design, manufacturing and evaluation of DC power supplies,
batteries, and power components. Other applications include fuel-cell and photovoltaic cell test. The
DC Load can operate under the following modes:
●
Draw a constant voltage from a DC source.
●
Draw a constant current from a DC source.
●
Draw a constant power from a DC source.
●
Present a constant resistance to the DC source (this behavior simulates a perfect resistor
