The load unit regulates the input power by measuring the input voltage and current and adjusting the input power
based on data streamed from the measurement ADCs.
Power may be programmed in one of three overlapping ranges, a Low, Medium and a High power range. The low
range provides better programming and measurement resolution at low power settings. The load unit have a built-
in over-power protection function that will not let you exceed 110% of the power rating of the load module (the Max
Power Contour).
CR mode
In this mode, the load unit will sink current proportional to the input voltage in accordance with the programmed
resistance.
The heavy solid line illustrates the locus of possible operating points as a function of the resistance. Resistance may
be programmed in one of three overlapping ranges - a Low, Medium, and a High resistance range. The lower ranges
provide better programming and measurement resolution at lower resistance settings. The load unit automatically
selects the resistance range that best corresponds to the resistance value that you program. If the resistance value
falls in a region where ranges overlap, the load selects the range with the highest resolution for the resistance value.
