4.7.1 DIN40839
This series power supply has built-in 12V or 24V DIN40839 waveform. This test
verifies the behavior of a DUT during and after cranking. This waveform can
reproduce the voltage curve for automotive power network confirms to
DIN40839 standard, thus facilitating quick call by customers.
For automotive startup voltage waveform, the startup voltage can also be set
based on customers' requirements. In this way, the user can create waveform
between 8V to 32V.
