Load Operating Modes
The load operating modes for Keysight EL30000 Series DC electronic load are:
– Constant current (CC) mode
– Constant voltage (CV) mode
– Constant power (CP) mode
– Constant resistance (CR) mode
When programmed to a mode, the electronic load remains in that mode until the mode is changed or until a fault
condition, such as an overpower or over-temperature occurs.
CC mode
In this mode, the load unit will sink a current in accordance with the programmed value regardless of the input
voltage.
The heavy solid vertical line illustrates the locus of possible operating points as a function of the load current. A CC
(constant current) status flag indicates that the load current is at the specified setting. A voltage limit is not
programmable in CC mode. Also, if the DUT imposes a voltage that is above 110% of the rated input voltage, the
overvoltage protection will trip and the load's input will turn off.
Current may be programmed in one of three overlapping ranges, a Low, Medium and a High current range. The low
range provides better programming and measurement resolution at low current settings.
