This voltage applies to all of the load input terminals of the AEL-5000 Series when the impedance of the EUT is relatively small. The voltage generated by the load wire inductance (L) and the current variation (I) is expressed using the following equation.
Page 132 In such event, the electronic load (AEL-5008- 350-75) may generate unstable oscillation. In such condition, the input voltage may exceed the maximum input voltage and Cause damage to the AEL-5000 series.

Page 191: Constant Power Mode Application
(Fig b). Operating the AEL-5000 Series electronic load in CP mode is ideal for testing the characteristics of a battery. This is because as the battery voltage drops the load current will automatically increase in order to keep the CP setting.
Page 192 AEL-5000 User Manual functions allow the ramp, fall and plateau times to be adjusted between 2 levels of power. This capability means that ‘real world’ loads can be more accurately simulated. For example the dynamic mode could be used to test the performance of a battery that is required to provide power pulses to transmit data from a radio frequency terminal.
