4-1-6. External Resistance Control
– Operation
Description External resistance control can be used to control the current,
voltage, resistance and power for CC, CR, CV and CP modes.
Configuration for each the operating mode is the same.
CC Mode Proportional Control:
Input current = rated current × (external resistance/10).
Inverse Control:
Input current = rated current ×
(1 - external resistance/10).

CR Mode Proportional Control:
Input conductance = rated conductance ×
(external resistance/10).
