4.2.3 AC+DC Mode
If the output mode select to AC+DC Mode, the instrument will simulate AC and
DC power supply, which can add DC component to AC voltage.
Set the output
voltage in the main interface, as shown in the figure below.
Under AC+DC mode, Set the output voltage and frequency of the AC power
supply in the main interface, and set the DC voltage in the configure menu.
Vac: you can set the Vac under the main interface or under the config interface.
DC: set the DC component under the config interface. The setting range is 10%
of rated voltage.
NOTE
The AC + DC mode not only expands the application range of pure AC voltage, but also
expands the application range of DC component in laboratory testing.When using AC+DC
for testing, please first understand the ripple parameters of the instrument when it is used
as a DC power supply. If there are strict noise requirements, additional DC noise filters are
needed to obtain low noise and good stable DC voltage for testing.
