CI, CR, CG, CV and CP modes | transient generator, variable slew rate Multiple modes of operation Constant Current Constant current mode is used for load testing of normal voltage-source power supplies and for constant current discharge testing of batteries. This mode provides rapid measurement of power source regulation (V/I characteristics). Constant Power Constant Resistance Constant resistance mode simulates a standard resistive load by providing a current drain proportional to voltage.

LD400 & LD400P - Technical Specifications (continued) DROPOUT VOLTAGE The load will cease to conduct if the applied voltage falls below the Dropout Voltage setting; active in all modes except Constant Voltage. The Dropout Voltage setting is also the threshold for the Slow Start facility and acts as an offset voltage in Constant Resistance mode. Setting Accuracy: ± 2% ± 20mV.
